Do algae eat plants?
As “plants” the algae produce their own food and as “animals” they can eat other plants or even their own grazers. These organisms are called mixotrophs and their nutritional strategy is thus known as mixotrophy, in other words: “mixed nutrition”.
How do Chlamydomonas live?
Chlamydomonas is a genus of green algae consisting of about 150 species all unicellular flagellates, found in stagnant water and on damp soil, in freshwater, seawater, and even in snow as “snow algae”….

How is Chlamydomonas Isogamous?
Most of the Chlamydomonas species are isogamous in nature. In isogamous reproduction the fusion of gametes, which are similar in size, shape and structure, take place. These gametes are morphologically similar but physiologically dissimilar. The thalli shed their walls and function as gametes.
Which algae produces Isogametes?
Ulothrix and Spirogyra produce isogametes.
How Zoospores are formed in Chlamydomonas?
The parent cell loses flagella or in some species of Chlamydomonas flagella are absorbed. Each 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.
Is Chlamydomonas a green algae?
Chlamydomonas reinhardtii is a single-celled green alga found in temperate soil habitats (Figure 1). It has proven to be such a powerful model for dissecting fundamental processes in biology that investigators have dubbed it the ‘green yeast’ (Goodenough, 1992; Rochaix, 1995).
What kind of water does Chlamydomonas live in?
Chlamydomonas is simple, unicellular, motile fresh water algae. It is mainly found in fresh water rich in nitrogen salts and organic matter. It is also found in stagnant water of ponds, pools, ditches, water tanks, sewage tanks and in slow running water. Chlamydomonas is planktonic algae and makes surface of water appear green.
How does reproduction take place in a Chlamydomonas?
The reproduction in Chlamydomonas is both asexual and sexual. (A) By zoospores- The zoospore formation takes place during favourable conditions. The zoospore formation takes place as follows: The protoplast contracts and gets separated from the cell wall. The parent cell loses flagella or in some species of Chlamydomonas flagella are absorbed.
How can we take advantage of the power of Chlamydomonas?
To take advantage of the power of Chlamydomonas genetics, a number of techniques have recently been developed to clone the genes in which mutations produce interesting phenotypes.
What kind of cell structure does Chlamydomonas nivalis have?
Red snow caused by Chlamydomonas nivalis. The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores.
