There are two copies of each autosome (chromosomes 1-22) in both females and males. The sex chromosomes are different: There are two copies of the X-chromosome in females, but males have a single X-chromosome and a Y-chromosome.
Euglena move by a flagellum (plural â flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the front end, and twirls in such a way as to pull the cell through the water. Color the reservoir grey and the flagellum black. Chloroplasts within the Euglena trap sunlight that is used for photosynthesis, and can be seen as several rod-like structures throughout the cell.
Chloroplasts are organelles located in a plant which help plants absorb sunlight and complete the process of photosynthesis. Chloroplasts structures include: membrane envelope, thylakoid membrane, grana, stroma, and chlorophyll.hloroplasts are the site where the photosynthesis function is performed. In short Photosynthesis occurs in eukaryotic cell structures called chloroplasts. A chloroplast is a type of plant cell organelle known as a plastid.
