How do the three classes of algae differ from each other in terms of flagellar number
and position?
Answers
Answer:
Explanation:
The three most prominent groups of algae are the brown algae, the red algae, and the green algae, amongst which some of the most complex forms belong to green algae.
Answer:
1. Red alage -Red algae do not have flagella and centrioles during their entire life cycle.Red algae are found around the world, from polar waters to the tropics, and are commonly found in tide pools and in coral reefs.
2. Brown algae-Brown algae are members of the Stramenopiles and their gametes generally have two heterogeneous flagella: a long anterior flagellum (AF) with mastigonemes and a short posterior flagellum (PF).Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat.
3. Green alage-The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds.Most green algae occur in fresh water, usually attached to submerged rocks and wood or as scum on stagnant water; there are also terrestrial and marine species. Free-floating microscopic species serve as food and oxygen sources for aquatic organisms.
