cell membrane

the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.

1 of 13

cytoplasm

the jellylike material outside the cell nucleus in which the organelles are located.

Golgi body

(also called the Golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins a

3 of 13

lysosome

(also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.

4 of 13

mitochondrion

spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the

5 of 13

ribosome

small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.

6 of 13

rough endoplasmic reticulum

Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transports materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane).

7 of 13

smooth endoplasmic reticulum

Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body, lysosomes, and membranes

8 of 13

vacuole

fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell

9 of 13

nucleus

spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.

10 of 13

nuclear membrane

the membrane that surrounds the nucleus.

11 of 13

nucleolus

an organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.
