Q1.
Now that you know how to identify a living being, fill up the remaining two columns (IV and V) of Table 10.1 and complete the activity.
Answer
Now use the eight characteristics as a checklist. Here is the completed Table 10.1.
| (I) Name | (II) My guess | (III) Reason / Remarks | (IV) Correct answer | (V) Reason / Remarks for the correct answer |
|---|---|---|---|---|
| Pencil | Non-living | Does not move or grow by itself | Non-living | Shows none of the eight characteristics — no nutrition, growth, respiration, excretion, response or reproduction |
| Book | Non-living | It just lies where it is kept | Non-living | Made from paper, which came from a tree — but the paper itself no longer grows, respires or responds |
| Pigeon | Living | It flies away when disturbed | Living | Moves, eats grain, grows from a chick, respires, excretes, responds, lays eggs and finally dies |
| Car | Non-living | It moves, but only with a driver | Non-living | Movement alone is not life. It takes fuel, not food; never grows; never reproduces |
| Plant | Living | It becomes taller | Living | Grows, makes its own food, respires through stomata, excretes droplets, bends towards light, produces seeds, and dies |
| House lizard | Living | It runs across the wall | Living | Catches insects, grows, respires, responds instantly to light and sound, lays eggs |
| Seed (the tricky one) | Non-living (a common first guess) | It lies still and does nothing | Living | It holds a tiny living embryo. Given water and air it germinates, grows and becomes a whole plant |
Why columns II and IV may differ: that difference is the whole point of the activity. A first guess is based on how a thing looks; the correct answer is based on testing it against the characteristics of life. The seed usually changes sides between column II and column IV.
