WebA typical eyespot is an orange-colored, membranous structure packed with pigmented granules. In algae, the eyespot membrane bears a specialized type of photoreceptors, which shows similarity with animal rhodopsin photoreceptors. This light-sensing receptor is responsible for the photo-mobility response known as phototaxis. WebEach daughter cell develops cell wall, flagella and transforms into zoospore (Fig. 6). The zoospores are liberated from the parent cell or zoosporangium by gelatinization or rupture of the cell wall. The zoospores are identical to the parent cell in structure but smaller in size. The zoospores simply enlarge to become mature Chlamydomonas.
