Life cycle of Chlamydomonas, Volvox, Ulva and Spirogyra
Characteristic for Green algae are the chloroplasts that are green due to the dominating presence of Chlorophyl a and b (besides other pigments). Green algae can be found in sea water, fresh water and in humid terrestial environments. In the phylogenetic hypothesis shown in the study book (see life cycles
) the group of the Green algae consists of the Chlorophyta together with the Charophytae. Common representants of the Chlorophytae are Chlamydomonas, Volvox and Ulva. Well-known representants of the Charophytae are Spirogyra, Zygnema and Desmides. Characteristics of these Green algae are further described here below.
