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 unique structures found in plant cells that specialize in converting sunlight into energy that plants can use. This process is called photosynthesis. Organelle. Chloroplasts are considered organelles in plant cells. Organelles are special structures in cells that perform specific functions. The main function of the chloroplast is photosynthesis. Most chloroplasts are oval-shaped blobs, but they can come in all sorts of shapes such as stars, cups, and ribbons.
