Ankistrodesmus falcatus is a green algae species characterized by its elongated and curved cells, resembling a sickle or falcate shape. Typically measuring between 20-50 micrometers in length and 5-10 micrometers in width, these cells can form loose colonies or exist individually. Each cell features a thin, smooth cell wall and contains one or more chloroplasts aligned along its length. Reproduction primarily occurs through binary fission, though sexual reproduction is less common. Ankistrodesmus falcatus thrives in freshwater habitats such as ponds, lakes, and slow-moving streams, where it contributes to ecosystem dynamics through photosynthesis and serves as a vital component of the aquatic food chain.
