Cytoplasm
|
The fluid between the nucleus and surface membrane
|
Plasma Membrane
|
Made of protein and lipids; regulates what goes in and out of the cell.
|
Organelles
|
Membrane bound particles in the cell.
|
Cytoskeleton
|
Supportive framework of the cell.
|
Cytosol
|
A clear gel that the cytoskeleton and organelles are embedded into.
|
Transmembrane Proteins
|
Proteins that pass through the membrane of the cell.
|
Glycocalyx
|
External to the plasma membrane; a fuzzy coat acts as an identification tag that distinguishes what particles are part of the body and which are foreign contaminents.
|
Microvilli
|
Extensions of the plasma membrane that increase a cell's surface area.
|
Cilia
|
Hairlike processes; serve as the cell's antenna for monitoring the outside environment.
|
Flagellum
|
Much longer than a cilium, only found on the sperm in humans.
|
Nucleus
|
Houses the genetic material of the cell.
|
Nuclear Envelope
|
Two unit membranes surrounding the nucelus; regulate what goes in and out of the nucleus.
|
Rough Endoplasmic Reticulum (Rough ER)
|
Produces the phospholipids and proteins of the plasma membrane.
|
Smooth Endoplasmic Reticulum (Smooth ER)
|
Synthesizes lipids.
|
Ribosomes
|
Read coded genetic messages (mRNA) and assemble amino acids into proteins specified by the code.
