Verified answer

Answer:

1.

The main difference between reticulate and parallel venation is that the reticular venation is the presence of a net- or web-like vein patterns on the leaf blade whereas the parallel venation is the presence of parallel patterns of veins on the leaf blade.

2.

Leaves can be modified in the form of spines that reduce water loss and also act as a defence. Some are modified into tendrils to provide support to the plant. Some leaves are thick that help in water storage. Some are modified to catch and digest insects.

3.

Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.

4.

This is a form of asexual reproduction in which new plants grow from the buds growing on the margin of the leaves. These buds are reproductive in nature and when they fall on the ground they germinate and form a new plant. Begonia and Bryophyllum are examples of vegetative propagation by leaves.

5.

They are known to be modified portions of leaf, stem or petiole. Their main function is to provide support to the plant as it climbs up a structure. By doing so they allow a plant to find a more suitable area to grow due to more light. When stems are modified into tendril they help plants to climb.
