Cell Membrane

Maintains integrity of cell and controls passage of materials into and out of cell

A double layer or bi-layer of phospholipid molecules

Cytoplasm

Where the cell activities occur and where nutrients are received, processed, and used

Contains organelles suspended in the clear liquid cytosol

Ribosomes

Golgi Apparatus

Refines, packages, and delivers protein synthesized ribosome associated with the endoplasmic reticulum

Looks like a group of flattened sacs

Mitochondria

The major site of chemical reactions that transform released energy from certain nutrient molecules into adenosine triphosphate

Rough E.R.

Provides a vast tubular network that transports molecules from one cell part to another

Composed of membrane-bounded flattened sacs

Smooth E.R.

Has enzymes important in lipid synthesis, absorption of fat from the digestive tract, & the metabolism of drugs

Also membrane bounded flattened sacs but doesn’t have ribosomes

Nucleus

The nucleus directs overall cell activities by housing the genetic material

Nucleolus

Produces ribosome for protein synthesis

Contains RNA for protein synthesis

Stem Cells

Stem cells can develop to many different cell types in the body. It serves of a repair system for the body.
