Questions and Answers
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.
Similarity: Both have chloroplasts and chlorophyll. Difference: Plants have connective tissues to transport nutrients and water, while algae absorb water individually through each cell.
Compare and contrast three mechanisms of motility displayed by protozoa.
Protozoa can move using flagella, cilia, and pseudopodia.

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.
