Identify the correct answer. i. The most common spores in algae ii. They are flagellated (motile) and on germination gives rise to new plants.
1 Aplanspores
2 Zoospores
3 Hypnospores
4 Phytospores
Explanation:
Algae produce different types of spores, the most common being the zoospores. These are motile, flagellated and give rise to new plants on germination.

Hydrocolloids are secreted by
1 All of the algae
2 Only brown algae
3 Both red and brown algae
4 Only green algae
Explanation:
Certain marine brown and red algae produce large amounts of hydrocolloids (water holding substances), e.g., algin (brown algae) and carrageen (red algae) which are used commercially.

The members of chlorophyceae usually have a rigid cell wall made up of
1 Cellulose (outer layer) and algin (inner layer)
2 Pectose (inner layer) and peptidoglycan (outer layer)
3 Cellulose (inner layer) and pectose (outer layer)
4 Cellulose (inner layer) and pectin (outer layer
Explanation:
Green algae usually have a rigid cell wall made of an inner layer of cellulose and an outer layer of pectose.
