What is the difference between colonial and filamentous forms of organisms ? (like algae).
PLEASE ANSWER FAST .........
- Green alagae or Cyanobacteria may be single-celled or colonial. Individual cyanobacteria are very small and usually just single cells, either round, ovoid, or string like in shape. Some types grow in colonies that can be large. Colonies may form filaments.
- In Colonial algae, groups of cells working together and show division of labor.
- Filamentous algae have slender, rod-shaped thallus arranged in rows joined end-to-end. They have a specialized structure called as holdfasts that attaches the algae. So, it can grow toward sunlight at the surface.
