How many plants among China rose, Ocimum, sunflower, mustard, Alstonia, guava, Calotropis and Nerium (oleander) have opposite phyllotaxy?

Question

What are some archaeological sites where Neanderthal remains and artifacts have been discovered?

Answer 1

The question tests your knowledge of plant phyllotaxy, which refers to the arrangement of leaves on the plant stem.

Phyllotaxy can be categorized into three main types:

Alternate Phyllotaxy: A single leaf arises at each node in an alternate manner, e.g., sunflower, mustard.
Opposite Phyllotaxy: A pair of leaves arises at each node, directly opposite to each other, e.g., Ocimum, Calotropis, guava.
Whorled Phyllotaxy: More than two leaves arise at each node and form a whorl, e.g., Alstonia, Nerium.

Let's analyze the given plants:

Based on the above analysis, the plants with opposite phyllotaxy are:

Thus, the correct answer to the question is Three.
