Question

Phylloclade is the modification of _______ for photosynthesis.

• A. Root
• B. Stem
• C. Leaf
• D. Flower

Answer 1

The correct option is B Stem

The phylloclade is the special modified photosynthetic stem in xerophytes. It is a green flattened or cylindrical structure that has distinct nodes and internodes. To check the rate of transpiration stems get modified and become flattened to carry out photosynthesis as leaves convert into spines thorns, a lesser number of stomata, etc. Phylloclades retain water in the form of mucilage. Examples: -Opuntia, Ruscus, etc.

So the correct option is Stem'.
