Description

Eudorina is a spherical colonial alga with 16, 32 or 48 Chlamydomonas-type cells grouped together in a gelatinous matrix. Each cell is spherical, with a large cup-shaped chloroplast, a pair of flagella and a prominent eyespot near the base of the flagella. The pair of flagella points towards the surface of the colony and the combined beating of the flagella of all the cells propel the colony forward.

General Biology

This is a freshwater alga found in puddles, ponds, ditches as well as planktons of softwater lakes.

Life Cycle

Reproduction by asexual means involves all the cells divide together to form colonies that are then liverated by the rupture of the colonial envelope. Sexual reproduction involves the cells of the colony developing into smaller male gametes and larger female gametes. After the fusion of these two types of gametes, a smooth-walled zygote forms, to eventually germinate into a colony of Eudorina.
