LIVING THINGS

There are many things around us; different types of plants, table,chair,soil,rock clothes,different animals,insects,birds. We can categorize them in various groups.Members of a common group share some common characteristics.We categorized materials as solids, liquids and gases.Another type of category is that of Living things and Non Living things.

  • The things around us that possess the characteristics listed above are known as living things. Those which do not possess these characteristics are known as non-living things.
  • You know that plants are also living beings like us. Plants grow like we do but do they move like us?
  • Is it essential for a living thing to have all of these properties or could a thing be considered living if it has some of these properties? Let's take a closer look at the characteristics of living things.
Movement in living beings:
  • How do the following living beings go from one place to another?
  • We see that plants don't move like us. Should we consider them as living beings.
  • There are some movements in plants for example,closing and opening of flowers.
  • We say that plants don't move but we find plants of the same types in different locations.How is this possible
  • Other than plantation by human beings there are many natural ways of seed dispersion. The seeds grow into plants and we feel that plants have moved from one place to another.
Food and living beings:
  • We have seen in the chapters on food that we as well as all other animals need food for smooth functioning of different activities.
  • Do plants also need food?
  • In the chapter "plants parts and functions", we have seen that some parts of plants like root, stem and fruits store food.
  • What are the sources of their food?
  • Most of the plants absorb water and minerals from the soil and prepare their food in the presence of sunlight. The leaf is the place where the food is prepared.
Note:
  • We also prepare food. Is our process of preparing food the same as that of the plants? By using carbon dioxide, green colour substance in the leaves and sunlight plants prepare their own food.This is called Photosynthesis.
Growth in living beings:

You notice that kittens, pups and chicks grow into adults. You become taller every year. Similarly, a seed germinates into a plant. Some plants grow day by day into trees. A human child grows into man/woman.Plants also produce branches that show their growth.They grow throughout their life but we don't grow like that. We will grow up to certain age and height. But some parts of the body grow throughout our life.Think what those parts are?

 Growth in Living Beings
Do all Living things Breath:
  • Human beings, plants and animals are called Living things.
  • Living things can do many things on their own.
  • living

    PLANTS LIVING THINGS
    • Plants are also living things.
    • A small plant is born from a seed and grows up to become a big plant.
    • living
    • Plants also need food and air to grow.
    • Plants do not move from one place to another. But they move their parts. Like, the sunflower turns it's face towards the Sun. The leaves of the touch-me-not plant close down when touched.

    Do all living things breath:

    Observe the abdomen of a cow when it is in rest position. How is it? It moves slowly. This shows that the cow is breathing. If you keep a finger in front of your nose, you feel air coming out of your nostrils. When we breathe in or inhale, air moves from outside to inside our body. When we breathe out or exhale the air inside comes out.

  • Do all birds have noses? How do they breathe?
  • Fish can't remain alive in air.How might they breathe while remaining in water?
  • Do all living things breathe? Do plants breathe like us? We know that they don't have a nose. How would they breathe? Let us try to understand.

     Fish In Water
    Activity-1:Plants has Nose:-
    • Take any fleshy leaf like, alovera.Peel from it and put it on a slide. Observe this under a microscope. You will see the structures as shown in picture.They are called stomata. These are useful for exchange of gases.
    •  Stomata
    Do all living things get rid of their waste?:

    We know that all living things take in food.After digestion, wastes have to be removed from the body.Our body produces different types of waste materials during different life processes.When we work hard our body becomes wet with sweat. This is a waste material. The process of getting rid of wastes is called Excretion.

    In what forms do animals excrete?
    • Animals excrete wastes in different forms - dung, urine, sweat etc.
    • Plants also excrete their wastes but this is not in the same way as animals.
    • Have you ever observed sticky substance on the stems of trees?Actually this gummy substance are the excretions.
    • Generally we feel that excretions are useless and foul smelling material.But excretory products of animals are used as manure.
    • Secretions of plants like,gums and resins, are also useful for us.
     Gummy Substance
    Living things give birth to young ones:

    Birds and animals that lay eggs for giving birth to young one are known as Oviparous. Those which give birth to young ones without laying eggs are known as Viviparous.

    Can plants be classified as Oviparous or Viviparous?
    • We know that seed germinates into plants.This means that plants also produce their young ones. Seed germination is one of the ways of doing this.
    Response to Stimulus:
    • All living beings possess the characteristic feature of response to stimulus.
    • How does this plant respond when you touch it? How much time does it take to return to its previous position?
    Atti-Patti:
    • It is very interesting to observe a touch me not (Atti-patti or Mimosa)plant.
     Touch Me Not
    • This observation explains that plants also respond to stimulus.Some plants bloom in the morning and some at night. These respond to sunlight.When winter comes many trees shed their leaves.They respond to change in temperature.
    Seeds-Living or not:

    Seeds are produced from plants.We know that plant is a living being. Can we say that seeds are also living?Let us discuss what characteristics of living beings seeds have?

    • Does a seed take in food? From where?
    • Will it die if stored for a long time?
    • What happens when a seed is sown in soil?
     Seeds
    • Seeds germinate and turn into a whole plant.So we can say that seed is a living thing. Can you think of any way of deciding whether dry seeds are living?
    • We can noticed that growth,breathing, excretion, taking food, giving birth to young ones, response to stimulus, movement are some of the characteristics of living beings. He also observed that these are not common among all living organisms.
    • But, non-living things do not possess these characters.He observed that people depend upon both living and non-living things.Generally we are told that the plant is dead when it has dry leaves and stem. If an animal doesn't show living characteristics, we can say that the animal is dead.Is a dead plant or a dead animal non-living?
    • Dead plants,animals or any other living beings decompose to form non-living constituents.So we can't say dead things are non-living things.They are intermediate things between living and non-living things.
    Microscope
    What is a microscope?:

    Microscope is an instrument with the help of which we are able to see minute things that we cannot see with our eyes.It works like a hand or magnifying lens but it is much more powerful.

     Microscope
    • Basically, there are two components in a microscope-The Structural Component and The Visual Components
    • Structural components are the head/body, base and arm.Visual components are eyepiece, objective, nose piece,coarse and fine adjustment knobs,stage,aperture etc.
    • In the shown figure a labelled diagram of a compound microscope.Taking its help identify different parts of microscope
    Bread Mould:

    What happens when you pack bread or vegetable and keep for a couple of days?You observe that they become rotten and there is a foul smell. We can see thin,thread like grey colour substance.After some days this grey colour substance turns black.If you touch this material black colour substance sticks to your fingers.

    Collect this rotten material and observe it under a microscope.Note your observation and discuss with your friends.Draw the structures seen by you under the microscope

     Microscope
    Bread Mould
    • These tiny thread like structure are commonly called mould. Can we say that mould is also living?
    • The mould that develops on spoiled material is able to produce new mould.It grows.So we can say the mould is also living.
    Let us see microscopic organisms:
    • The micro-organisms that you see under the microscope are called Bacteria.Bacteria are in different shapes.The bacterium that you see in curd is helpful.This bacteria helps to convert milk into curd.
    Living things under a microscope:
    • The letters in a book are quiet small.What do old people do to read books? Children frequently play with magnifying lens. When we see objects through magnifying lens they seem to be bigger than their actual size.
    Are bacteria harmful?:
    • Some bacteria cause diseases in human beings as well as animals and birds.These bacteria spread from one person to the other and cause various types of diseases.They spread all over the world.There is no place in the world without bacteria.
     Microscope
    Bacteria
    Micro organisms in water:
    • When you suffer from a disease,the doctor advises you to take boiled water.Are there micro-organisms in water?Is the water that you drink regularly,pure?
    • Collect water samples from a pond, well,bore well. Keep them separately.Put a drop of water on a slide.Keep another slide on it. Observe under microscope.What type of micro-organisms do you see in water samples?Do all water samples have the same type of micro-organisms?Is there any water without micro-organisms?Which water contains larger number of micro-organisms?Draw what you have observed.Describe the shapes of the micro-organisms.
    • Which water contains larger number of micro-organisms?Why?
    • What difference do you find in the appearance of micro-organisms in pond water and bore well water?
     Microscope
    • Thus we see that micro-organisms are present everywhere, although they are not visible to naked eyes.From our activities, we could see only a few of them.But there is a vast world of micro-organisms and they are all part of the living world.
    What we have learnt:
    • There are living and non-living things around us.
    • When living things lose their life they become dead.
    • Dead is an intermediate stage between living and non-living things.
    • Dead material decomposes to form non-living things.
    • Living things possess characteristics like growth,breathing, excretion, movement, response to stimulus and giving birth to young ones.
    • Among living things, plants and trees can't move like animals.
    • Seed is also a living thing but it doesn't have all characteristics of the living world
    • We can see minute things under a microscope.

    NON-LIVING THINGS

    • Non-living things cannot eat, breathe or feel. They cannot move or grow. They also cannot have babies.
    • Non-living things are divided into two groups - Natural things and Man-made things.
    • Natural things are found in nature. These are not made by man.
