Anabaena wetmount, bacteria, bacteria, unicellular

what are long filaments of single cells called?

filamentous colonies

does anabaena have chlorophyll and chloroplast?

Yes, no (it is prokaryotic)

What are vegetative cells?

regular cells that do photosynthesis

What are heterocysts?

fix nitrogen so anabaena can use it

What are algal blooms caused by?

cyanobacteria

Why are cyanobacteria more advantages in comparison to algae in terms of growth?

Because they have heterocysts that give them advantage in nutrient-poor environments

Describe what a red tide is and why it can be harmful to vertebrates.

harmful algal bloom, caused by dinoflagellates, release toxins that kill fish and harm animals
