Chlamydomonas is multicellular
WebOct 12, 2024 · Chlamydomonas is a small (<10 um) unicellular , mobile organism. It is roughly spherical in shape with two anterior flagellae that it uses to 'swim' in a breast-stroke-like manner. Unlike many green algae, the cell wall is not made of cellulose (as it is in land plants) but instead of a glycoprotein. Reproduction WebThis chapter details what is known about these multicellular relatives of Chlamydomonas, including their phylogeny, ecology, morphologies, life histories, genetics, genomes, and evolution. It highlights the most compelling questions that remain unanswered about their biology and origins, and it describes the available tools that should make it ...
