In which domains are algae, protozoa, and cyanobacteria classified?
Algae and protozoa are eukaryotes. Cyanobacteria is a prokaryote.
Name one similarity and one difference between algae and plants.
Name one similarity and one difference between algae and plants.
Similarity: Both have chloroplasts and chlorophyll. Difference: Plants have connective tissues to transport nutrients and water, while algae absorb water individually through each cell.

Study Notes
Classification of Organisms
- Algae and protozoa are classified as eukaryotes.
- Cyanobacteria is classified as prokaryotes due to its bacterial nature.
Similarities and Differences between Algae and Plants
- Both algae and plants contain chloroplasts and chlorophyll, enabling photosynthesis.
- Plants have connective tissues for nutrient and water transport; algae rely on individual cells to absorb water.
Mechanisms of Motility in Protozoa
- Flagella and cilia are used for propulsion in protozoa.
- Pseudopodia are cytoplasmic extensions that aid in movement.
Cyanobacteria vs. Algae
- Cyanobacteria, formerly known as blue-green algae, are not true algae.
- Cyanobacteria have no organized nucleus or chloroplasts and possess peptidoglycan in their cell walls, categorizing them as prokaryotes. Algae are eukaryotic.
Red Tides
- Red tides are caused by increased nutrient levels that lead to the proliferation of red marine dinoflagellates.
Causative Agent of Malaria
- Malaria is caused by the genus Plasmodium, belonging to the phylum Apicomplexa.
