WebChlamydomonas 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. WebThe cell wall at the anterior end is extended to make apical papilla. In some species the outer pectose layer dissolves in water medium to make gelatinous layer outer to cell …
