A neem branch carries leaves. Each leaf is pinnately compound, with pairs of leaflets and one leaflet at the tip.
- How many leaflets are on one leaf?
- How many leaflets are on the whole branch?
- How many axillary buds are in the axils of the leaves and the leaflets together?
Need a reminder? The key ideaShow
A leaf has a leaf base, a petiole and a lamina with a midrib and veins. Venation is reticulate (dicots) or parallel (monocots). A simple leaf is cut, if at all, short of the midrib. A compound leaf is cut to the midrib into leaflets, pinnate on a rachis (neem) or palmate from the tip of the petiole (silk cotton). Phyllotaxy is alternate, opposite or whorled. Leaves change for climbing (pea), defence (cactus), storage (onion) and trapping insects (pitcher plant).
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. One leaf. leaflets.
Step 2. The branch. leaflets.
Step 3. Buds. A leaflet has no bud in its axil. Each of the leaves has one. So there are axillary buds.
Answer: leaflets; leaflets; buds.
