What is the foundation for algae classification?
Answer (1)
According to the NCERT Class 11 Biology Chapter 3 Plant Kingdom Notes,
The presence or lack of pigments is the primary foundation for classifying algae. The categorisation is as follows:
- Chlorophyceae : Green algae are members of the Chlorophyceae family. Because chlorophyll a and b pigments predominate, they are usually grass green.
- Phaeophyceae : Brown algae, also known as Phaeophyceae, are mostly found in marine environments. Chlorophyll a, c, carotenoids, and xanthophylls are all present in them.
- Rhodophyceae : Rhodophyceae members are usually referred to as red algae due to the preponderance of the red pigment r-phycoerythrin in their bodies.
