DIFFERENCE BETWEEN NON-LIVING AND DEAD
We can call only those things as dead, which once lived and followed the life cycle. For
example, we can call wood and leather dead because they come from organisms who
once lived. But a chair made of wood or a shoe made of leather are non-living. Stone,
water and car are non-living because they never showed any of the characteris cs of
living things.

Cell : The smallest structured unit of living beings

Molecule : The structural unit of non-living beings
Unicellular : Organisms made up of a single cell
Multicellular : Organisms made up many cells

Geotropism : The movement of plants towards the gravity
Photogropism : The movement of plants towards the light
Seedling : A new born plant

Mammals : Animals that feed their milk to their babies
Stimulus : The change around us that makes us react
Response : The action taken by us according to the stimulus

i Everything that surrounds us is either living or non-living and the only characteristic that
bifurcates these two is life.
i All the living and non-living beings are made up of matter.
i Non-living things do not have cells and don’t grow or show locomotion/movement.

i Living beings grow, respire, feed, excrete, reproduce, move, feel and die.
i Plants prepare their food on their own through the process of photosynthesis.
i Rat, dog, man, cow, etc. are multicellular organisms.

i Except mammals, all the other animals lay eggs.
i Different kinds of plants live for different time periods.
i Plants and animals are both living beings, but there are many differences in their structure,
shape, size and the ways they carry out different life processes.

i Multicellular organisms made up of many cells and also differ in shapes and sizes.
