Exploring Different Types of Algae

What type of algae live in highly saline water?

• Terrestrial algae

• Halophilic algae

• Freshwater algae

• Marine algae

Name an example of cryophilic algae.

• Chlamydomonas nivalis

• Spirulina platensis

• Dunaliella salina

• Chlamydomonas reinhardtii

Which algae are known to thrive in hot springs?

• Cyanobacteria and green algae (e.g., Synechococcus, Thermosynechococcus, Chlamydomonas)

• Diatoms (e.g., Thalassiosira)

• Red algae (e.g., Porphyra)

• Brown algae (e.g., Laminaria)

What is the habitat of edaphic algae?

• Soil environments, particularly moist or wet soils.

• Aquatic environments, such as oceans and lakes.

• Desert regions with minimal moisture.

• High-altitude rocky surfaces.

Give an example of lithophytic algae.

• Spirulina

• Euglena

• Cladophora

• Chlorella

What are planktonic algae?

• Planktonic algae are microscopic, free-floating plants found in aquatic environments.

• Planktonic algae are animals that live in freshwater.

• Planktonic algae are terrestrial plants found in soil.

• Planktonic algae are large, visible seaweeds.

Which algae can be found in snow and ice?

• Chlamydomonas nivalis

• Spirulina maxima

• Phaeocystis antarctica

• Dunaliella salina

Name a thermophilic algae species.

• Spirulina platensis

• Cyanidium caldarium

• Chlorella vulgaris

• Euglena gracilis

What type of algae grows on moist rocks or stones?

• Moss

• Fungi

• Lichens

• Liverworts

How do halophytic algae adapt to their environment?

• By producing more chlorophyll for photosynthesis

• By growing in freshwater environments

• By absorbing excess water to dilute salt

• Halophytic algae adapt by accumulating osmoprotectants, managing salt concentrations, and developing protective pigments.
