A plant cell. (which usually has more than one chloroplast) (and also, plants are eukaryotes)
bacteria
A plant cell.
Animal Cells
Mitochondria and Chloroplasts, this is to do with the endosymbiotic theory.
Muscle cells are very active relatively to the skin cell. So it has more mitochondria
The muscle cell
Muscle Cells
"muscle"
Muscle cells have more mitochondria because they require more energy to contract than skin cells.
It is believed that cyanobacteria, also known as blue-green algae, evolved into the eukaryote chloroplast through a process called endosymbiosis. This process involved a cyanobacterium being engulfed by a eukaryotic cell and forming a symbiotic relationship, eventually leading to the development of the chloroplast organelle found in plant and algal cells.
