Answer:
Explanation:
DIFFERENCES BETWEEN HARD BODY PARTS.
•Cyanobacteria have calcified sheaths.
• Diatoms have hard but porous cell wall.
• Coccolithophores have hard body parts.
• Silicoflagellates skeleton is composed of opaline silica.
• Dinoflagellates do not have hard body parts
• Green algae - no hard body parts.
• Brown algae - no hard body parts.
DIFFERENCES BETWEEN DISTRIBUTION
• Cyanobacteria are found almost in every terrestrial habitat on planet.
• Diatoms are found in oceans, freshwater, soil and damp.
• Coccolithophores are exclusively marine.
• Silicoflagellates are found in marine environment.
• Dinoflagellates are both freshwater and marine.
• Green algae grow on objects that do not move such as substrate, rock.
• Brown algae - wide distribution from tropical to polar zones.
DIFFERENCES BETWEEN REPRODUCTION.
• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.
• Diatom - asexually by cell division through mitosis.
• Coccolithophores - asexually by binary fission.
• Silicoflagellates - asexually
• Dinoflagellates - asexually
• Green algae - sexually or asexually by cell division, fragmentation, spore formation.
• Brown algae - sexually and asexually.
