Question

The type of phyllotaxy found in Calotropis is.

• A. Alternate
• B. Opposite decussate
• C. Opposite superposed
• D. Ternate

Answer 1

The correct option is B Opposite decussate

• Phyllotaxis is the phenomenon of the mode of arrangement of leaves on the stem. It is of the three types, which are alternate, opposite and worked.
• In the alternate phyllotaxy, a single leaf will arise from the node.
• In opposite phyllotaxy, two leaves arise from the node but in opposite directions. It is happening in guava and Calotropis.
• In whorled phyllotaxy, more than two leaves arise from the node as in Alstonia. Thus, the correct answer is "Opposite decussate"
• Option B is correct here.
