6. • Living organisms is made up of the
building blocks called cells.
A cell is the smallest living unit of an
organism.
It is the structural and functional
unit of all living organisms. It is so
small that it can only be seen
under a microscope.
11. Make a port folio of your pictures at
different ages.

13. Growth is the gradual increase in size
of an organism as it matures.
As a plant or animal develops, it
becomes heavier and larger. It is due
to increase in number of cells within
the body of an organism.
14. Growth of plants is different from animals. A
tree grows through out its life, but animals
stop growing when they reach a certain age.
Non living things do not grow. But some
increase in size , not due to cell division.

16. Why do animals move?
1. In search of food and shelter.
2. To escape from enemies
This movement from one place to other is called locomotion.
17.
18. Movement in plants is not as obvious in
animals. Different parts of plants grow
towards light, soil or water.
Non living things cannot move by
themselves. They need an external force to
make it move.
19.
20. An organism needs food in order to
get energy to move and grow.
Plants prepare food by the process of
photosynthesis. Animals directly or
indirectly depend on plants for food.
21. Green plants are known as autotrophs,
since they prepare their food
Animals and fungi are known as
heterotrophs since they do not
prepare their own food.
30. METABOLISM
The breaking down of substances
in the body for the release of
energy or for the growth of the
body is called metabolism.
31. The process by which waste material is
removed from the body is called excretion.
Undigested food and some products of
metabolism are excreted as faeces.
