(a) Stipules are the leaf like structure that grows on the leaf base

(b) The margin of the lamina can be entire, wavy or notched and the tip of the lamina can be round, acute or obtuse

(c) The arrangement of veins and veinlets in the leaf is called venation and veins are the vascular tissues of leaves

(d) In pinnate reticulate, there are many strong ribs and these ribs can be either convergent or divergent

This question was addressed to me in unit test.

This is a very interesting question from Flowering Plants Morphology in portion Morphology of Flowering Plants of Biology – Class 11

Answer 1

The correct option is (d) In pinnate reticulate, there are many strong ribs and these ribs can be either convergent or divergent

For explanation: Stipules are the leaf like structure that grows on the leaf base. The margin of the lamina can be entire, wavy or notched and the tip of the lamina can be round, acute or obtuse. The arrangement of veins and veinlets in the leaf is called venation and veins are the vascular tissues of leaves. In pinnate reticulate, only one strong mid-rib is present.
