Chlamydomonas is a genus of green algae consisting of nutrition in algae pdf flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as “snow algae”. Chlamydomonas is used as a model organism for molecular biology, especially studies of flagellar motility and chloroplast dynamics, biogeneses, and genetics.

Some regulatory systems of Chlamydomonas are more complex than their homologs in Gymnosperms, with evolutionarily related regulatory proteins being larger and containing additional domains. Chlamydomonas” lineages are to be reclassificated. Drawings of Chlamydomonas caudata Wille. It is generally found in habitat rich in ammonium salt.

Chlamydomonas possesses red eye spots for photosensitivity and reproduces by both asexual and sexual means. Most species are obligate phototrophs but C. Cell wall is made up of glycoprotein and non cellulosic polysaccharides instead of cellulose.

Two anteriorly inserted whiplash flagella. Flagella originates from a basal granule located in the anterior papillate or non-papillate region of the cytoplasm. 2 arrangement of the component fibrils. Contractile vacuoles found at near the bases of flagella.

Prominent cup or bowl shaped chloroplast is present. The chloroplast contains bands composed of a variable number of the photosynthetic thylakoids which are not organised into grana-like structures. The nucleus is enclosed in a cup-shaped chloroplast, which has a single large pyrenoid where starch is formed from photosynthetic products. Pyrenoid with starch sheath is present in the posterior end of the chloroplast.
