Which of the following is the green expanded part of leaf with vein and veinlets?
1 Petiole
2 Node
3 Stipule
4 Lamina
Explanation:
(d) Lamina on the leaf blade is usually flattened green photosynthetic part consisting leaf veins and veinlets. Its upper surface is called adaxial while the lower surface is called abaxial. The shape margin, apex, surface and extent of incision of lamina vary in different leaves.

Leaves of dicotyledonous plants possess venation, while venation is the characteristic of most monocotyledons.
1 reticulate and parallel
2 parallel and reticulate
3 reticulate and perpendicular
4 obliquely and parallel
Explanation:
(a) Leaves of dicotyledonous plants possess reticulate venation while parallel venation is the characteristics of most monocotyledonous. In reticulate venation, the main veins of leaf form numerous irregular branches and as a result a net like arrangements is formed. Reticulated venation is the most common vein formation in leaves. It can be found in the leaves of maple trees, oak trees and rose bushes.
In parallel venation veins are arranged parallel to each other.

The main purpose of phyllotaxy for the leaves is to provide sufficient______
1 soil
2 air
3 water
4 light
Explanation:
(d) The arrangement of mature leaves on the stem or its branches is called phyllotaxy. These are meant for getting maximum amount of light for photosynthesis.

Alternate type of phyllotaxy is found in
1 china rose
2 mustard
3 sunflower
4 all of these
Explanation:
(d) In alternate (or spiral) type of phyllotaxy, only one leaf is borne at each node and leaves are arranged
alternatively giving a spiral form. Example chinarose, mustard and sunflower.
