(a) Name the characteristics of living things.
(b) Explain the difference between the growth of plants and animals.
(c) How does excretion take place in plants?
(d) State the differences between living and non-living things.
(a) The characteristics of living things are as follows:
(i) Cellular structure: The body of all the living things is made up of cells.
(ii) Movement: All the living things show movement.
(iii) Responsiveness to stimuli: All the living things respond to the stimuli received from the surroundings. This characteristic of living things is known as responsiveness to stimuli.
(iv) Growth: All the living things such as plants and animals grow. However, animals grow for a definite period of time while plants continue to grow as long as they live.
(v) Respiration: Respiration is a continuous process in all the living things.
(vi) Reproduction: A living organism produces another living organism of its own kind by the process of reproduction.
(vii) Excretion: The process of passing out waste substances from the body is called excretion. All living things exhibit the process of excretion.
(viii) Death: Every living thing has a definite life-span after which death occurs in all the living things.
(b) The difference between the growth of plants and animals are as follows:
Growth of animals
Growth of plants
1.
Growth of animals takes place for a limited period of time.
There is no time-limit for the growth of plants.
2.
Growth takes place in all the body parts.
Growth takes place in specific parts.
(c) Plants excrete waste materials in the form of water vapours. There are some plants such as babhul, neem or drumstick whose stem secrete gum that is also a waste material.
(d) The difference between living and non−living thing are as follows:
Living things
Non−living things
1.
Living things show movement of their own accord.
Non−living things do not show movement of their own accord.
2.
All living things show response to stimuli.
Non−living things lack the ability to respond to stimuli.
3.
All living things show growth.
There is no growth in non−living things.
4.
Respiration occurs in living things for oxidizing food and for releasing energy.
Respiration does not occur in non−living things.
5.
Reproduction occurs in living things to continue their generation.
Non−living things do not reproduce.
6.
Living things remove waste material from their body through excretion.
Non−living things do not exhibit the process of excretion.
7.
All living things die after a particular life−span.
Non−living things do not die.
