Question

Write a note on phylloclade.

Answer

Plants growing in deserts try to store water. If the surface area is large, more water is lost by evaporation.
In plants like cactus, the stem is thick and becomes flat like leaves to do photosynthesis.
The leaves are reduced to small spines with less surface area. This kind of modification is called phylloclade. e.g. cactus.
