Chlamydomonas
Chlamydomonas is a motile, unicellular alga found in soil, lakes, and ditches. It probably has the most primitive structure and type of
reproduction among green algae. The egg-shaped cells of Chlamydomonas contain a large chloroplast and a pyrenoid involved in the production and storage of starch. Typically their single-cell body is approximately spherical, about 0.02 mm across, with a cell wall
surrounding the cytoplasm and a central nucleus.
Two filaments of cytoplasm, flagella, extend from one end, and their whip-like lashings pull the chlamydomonas through the water and rotate it at the same time. A single, cup-shaped chloroplast occupies the greater part of the cell. In this chloroplast is a protein region called a pyrenoid, which is involved in starch production and may be surrounded by starch granules.

Syngamy is the pairing and fusion of haploid gametes to form diploid cells. The zygote surrounds itself with a resistant surface and is called a zygospore. Under favourable conditions the zygote undergoes meiosis to produce haploid individuals called spores.
Spores are reproductive cells capable of developing into an adult without fusing with another cell.
