5. In which plant does the stem perform the
main function of a leaf?​

Answer 1

Answer:

In some xerophytes the stems perform the functions of leaf.In the genus Euphorbia,leaves are caducous i.e they fall immediately after their formation or if they persist on the plant they are reduced.These features help these xerophytes to cut down the transpiration rate.These stems are called as phylloclades.

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
