Chlorophyta-5  

Chlorococcales  

These are nonmotile & nonfilamentous organisms. Reproductive cells may be motile. The latter look like Chlamydomonas.

These range from single cells to complex organisms but they do not reach the level of Parenchyma tissue.

Chlorella and Chlorococcum are the most simple forms.

Colonial forms are displayed below.

These are ubiquitous in standing fresh water and are important components of freshwater ecosystems.

They have important symbiotic relationships with fungi to form Lichens.
