Question

What is the basis of classification of Algae?​

Answer 1

Answer:

Algae are classified depending on their characteristics and structure; including photosynthetic pigmentation, storage products, flagella, the structures of the cell wall, nucleus, chloroplast, pyrenoid (part of the chloroplast used in producing starch) and the eyespot (organelle composed of tightly packed lipids). Algae can be either prokaryotic (lacking a cellular membrane; classified in the monera kingdom) or eukaryotic (the cellular organelles are bound by a nuclear membrane; classified in the protista or plantae kingdoms). There are about sixteen different types of alga known or defined and are grouped depending on their structure and location of growth......

Answer 2

The presence or absence of pigments is the main basis of classification of algae:-

1. Chlorophyceae:- In this type of algae Chlorophyll a and b are present and impart green colour pigment. These are also called as ‘blue-green algae’.

2. Phaeophyceae:- This type of algae Chlorophyll a and c along with fucoxanthin are present. Fucoxanthin imparts brown colour to the algae . And are also known as ‘brown algae’.

3. Rhodophyceae:- -These algae has chlorophyll a and d and phycoerythrin are present. It imparts red colour. And are also called ‘red algae’.
