Question

classify the algae on the basis of photosynthetic pigment and food​

Answer 1

Answer:

Chlorophyceae, Phaeophyceae, and Rhodophyceae are the three primary classes of algae. These divisions are made on the basis of the following criteria:

• The presence of major photosynthetic pigments  
• The type of stored food
• The composition of the cell wall
• The number of flagella and their insertion place

Explanation:

Algae are classified into three groups. The presence or lack of pigments is the primary criterion for categorizing algae. Three types of algae are listed below: -

• Chlorophyceae: They contain chlorophyll a and b, which give them a green tint. Green algae are also known as Chlorophyceae.
• Phaeophyceae:  Chlorophyll a and c, as well as fucoxanthin, are found in the Phaeophyceae family. Brown colour comes from fucoxanthin. Brown algae are also known as Phaeophyceae.
• Rhodophyceae:  Chlorophyll a and d, as well as phycoerythrin, are found in Rhodophyceae. Phycoerythrin is a red pigment. The Rhodophyceae family is commonly known as "red algae."
