The upcoming discussion will update you about the differences among Red, Brown and Green Algae.
Difference # Red Algae:
1. Mostly marine.
2. Unicellular species fewer.
3. Thylakoids are un-stacked.
4. Chlorophyll— a and d type.
5. Fucoxanthin may be present.
6. Phycobilins present.
7. Reserve food is floridean starch.
8. Motile stages are absent.
9. Cell wall contains cellulose and sulphated phycocolloids.
Difference # Brown Algae:
1. Mostly marine.
2. Unicellular species absent.
3. Thylakoids occur in groups of threes.
4. Chlorophyll- a and c type.
5. Fucoxanthin is abundant.
6. Phycobilins absent.
7. Reserve food is laminarin.
8. Present; flagella 2, lateral and unequal.
9. Cell wall contains cellulose and non-sulphated phycocolloids.
Difference # Green Algae:
1. Mostly fresh water and sub-aerial.
2. Unicellular species abundant.
3. Thylakoids are stacked in groups of 2-20.
4. Chlorophyll— a and b type.
5. Fucoxanthin is absent.
6. Phycobilins absent.
7. Reserve food is starch.
8. Present; flagella 2 to 8 apical and equal.
9. Cell wall is of cellulose.
