Lobomonas

Lobomonas is a genus of green algae belonging to the family Chlamydomonadaceae. These single-celled organisms are found in freshwater environments and are characterized by their distinct cell shape and flagellar arrangement.

Lobomonas cells are typically oval or elliptical, often possessing a pronounced anterior papilla (a nipple-like projection). They possess two flagella, which are used for motility. A single, cup-shaped chloroplast occupies a significant portion of the cell volume, and this chloroplast contains a pyrenoid, a structure associated with carbon fixation. The cells also contain an eyespot (stigma), a light-sensitive organelle that aids in phototaxis, allowing them to move towards or away from light.

Lobomonas reproduce asexually via cell division. Sexual reproduction has also been observed in some species, typically involving the formation of zygospores which can withstand unfavorable conditions.

The classification and taxonomy within the Lobomonas genus are subject to ongoing research and revision.
