Answers

Answer 1
Answer: Homologous structures

Homologous structures refer to structures that have similar characteristics in terms of morphology, anatomy, genetics, and embryology yet still different when their functions are concerned. On the other hand, analogous structures are those organisms that have similar lifestyle because they live in the same habitat yet they belong in different groups.

The major light absorbing pigment in green plant photosynthesis isA)
rhodophyll.
B)
chlorophyll.
C)
cytochrome a.
D)
cytochrome c.

Answers

Chlorophyll is the major light absorbing pigment in green plant photosynthesis. the correct option in regards to the given question is option "B". For the process of photosynthesis it is important for a plant to absorb heat from sunlight to make glucose and water. The absorption of heat from sunlight is done by the chlorophyll present in the leaves. Without the presence of this green pigment in the leaves, the plants would never be able to absorb sunlight and this will ultimately lead to the death of the plant.
I think the answer would be, B. Chlorophyll
