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.
(a)(b)(c)(d)(e)(f)(g)
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.

LeafWhat the picture showsThe plant
(a)Heart-shaped, with a long thin tail drawn out at the tipPeepal
(b)One stalk carrying many narrow, curved leaflets with toothed edgesNeem
(c)Broad and oval, with a pointed tip and thick side veinsBanyan
(d)Very large, broad and rounded, with a thick midribTeak (sagaun)
(e)Long and narrow, dark green, with a smooth edge and a pointed tipMango
(f)Long oval, light green, with side veins that are easy to seeGuava
(g)Small, with a saw-toothed edge all roundRose
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.

The table as it is printed in the book, with the lemon row filled as an example.
Answer

Do it like this: pick up four or five fallen leaves near your home. Look at each one in the light, rub it between your fingers, and smell it. Then fill one row for each leaf.

Sample answer — a completed table.

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.
