These sand grains rupture diatoms and other algal cells during digestion.

They can also indirectly cause oxygen depletion at greater depths, through microbial breakdown of dead algal cells.

DOC may also be released into the environment by algal cells.

They make small groups of algal cells surrounded by fungal filaments.

When good conditions resume, the zygospore will germinate, undergo meiosis, and produce new haploid algal cells.

To assume that all the chlorophyll is contained in diatoms and other algal cells of similar size may, however, be misleading.

The algal cells are moved to its tentacles, where they continue to live.

In this partnership the algal cells live inside the fungus tissue.

This system utilizes low energy lights in a helical pattern, enabling each algal cell to obtain the required amount of light.

Sunlight can only penetrate a few inches through algal cells, making light a limiting reagent in open-pond algae farms.
