Q1.
During the visit to the nature trail, students collected leaves from different plants. Help them identify the plants based on the pictures of the leaves given below.The seven leaves the students collected, labelled (a) to (g).
Answer
Name a leaf by looking at three things: its shape, its edge, and its veins.
Leaf
What the picture shows
The plant
(a)
Heart-shaped, with a long thin tail drawn out at the tip
Peepal
(b)
One stalk carrying many narrow, curved leaflets with toothed edges
Neem
(c)
Broad and oval, with a pointed tip and thick side veins
Banyan
(d)
Very large, broad and rounded, with a thick midrib
Teak (sagaun)
(e)
Long and narrow, dark green, with a smooth edge and a pointed tip
Mango
(f)
Long oval, light green, with side veins that are easy to see
Guava
(g)
Small, with a saw-toothed edge all round
Rose
Why the shape is enough: Every kind of plant makes leaves of its own shape, and it makes them the same way every time. So the shape of one leaf is enough to name the plant it came from.
Tip: Leaves differ a little from place to place, and the book gives no answer key. Hold a real leaf from your school ground beside each picture. Your teacher may name a different plant of your area for (c), (d), (f) and (g) — write down that name, because it is the plant you can actually go and see.

What the table shows: No two kinds of leaves are exactly alike. Colour, shape, feel, smell and the lines on the leaf taken together tell us which plant it belongs to.
Tip: Pick up leaves that have already fallen. Do not pluck fresh leaves from a plant — the plant needs them.
