Spirulina vs Chlorella: Two Very Different Microalgae
Spirulina and Chlorella look similar in a jar but differ in biology, culture needs and uses. A direct comparison to help you…
-
Cyanobacteria vs Algae: Why Spirulina Isn’t an Alga
Spirulina is a cyanobacterium, not an alga. What that means in biology, how the two groups differ and why the difference matters…

How Chlorella Reproduces
Chlorella reproduces by autospores, not by splitting in two. One mother cell makes 2, 4, 8 or 16 daughters, which is why…
