Solution
The correct option is B Opposite
Phyllotaxy
The arrangement of leaves on the stem of a plant is called phyllotaxy.
Opposite
The phyllotaxy in which two leaves arise from each node and are opposite to one another is called the opposite phyllotaxy.
It may be of two types:-
- Opposite decussate- where the leaves of two adjacent nodes are 90 degrees to each other. For example, in Guava opposite decussate phyllotaxy is seen.
- Opposite superimposed- where the leaves of two adjacent nodes lie on the same plane. For example, in Syzygium opposite superposed phyllotaxy is seen.
