Which of the following plant groups have similar pigment composition :...
similarities between Cyanobacteria and Rhodophyta are as follows:
Both groups have Chlorophyll 'a' and similar accessory pigments such as β- carotenes, and phycobiliproteins.
Both groups show thylakoids which occur singly as opposed to the stacked arrangement seen in other algal groups.
Major food reserve of Cyanobacteria and Rhodophycean starch are quite similar to each other.
Both groups have no flagellate forms.

Which of the following plant groups have similar pigment composition :...
Rhodophyta and cyanophyta have similar pigment composition.
Explanation:
- Pigments are light-absorbing molecules that are responsible for the color of plants and algae.
- Different groups of algae have different types and combinations of pigments.
- Rhodophyta (red algae) and cyanophyta (blue-green algae) are two groups of algae that have similar pigment composition.
- Both these groups have chlorophyll a as their primary photosynthetic pigment.
- In addition to chlorophyll a, they also have phycobiliproteins, which are accessory pigments that appear red or blue-green in color.
- The phycobiliproteins help these algae to absorb light more efficiently in deeper waters, where other wavelengths of light are absorbed by water.
- Rhodophyta also have phycoerythrin, which gives them a red color, while cyanophyta have phycocyanin, which gives them a blue-green color.
- Therefore, the correct answer is option C, Rhodophyta and cyanophyta.
