See the below image for the Organelles of a cell diagram. An organelle is a tiny cellular structure that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells . In the more complex eukaryotic cells , organelles are often enclosed by their own membrane .
Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins. An organelle is a specific structure within a cell, and there are many different types of organelles. Organelles are also called vesicles within a cell.
Eukaryotic Organelles. Chloroplasts absorb the sun’s light energy for photosynthesis . Cell Wall – this rigid outer wall is positioned next to the cell membrane in most plant cells. Not found in animal cells, the cell wall helps to provide support and protection for the cell.
