|
Prokaryote
|
A cell with no nucleus in which to store genentic material (e.g. Blood cells and Bacteria)
|
|
|
Eukaryote
|
A cell with an enclosed nucleus in which ir stores genentic material
|
|
|
Cell Membrane
|
The external structure that contains the cells contents, Regulates what travels in and out of the cell; Phsopholipid bilayer
|
|
|
Nucleus
|
The Largest of the organelles, it contains:
*Deoxyribonucleic Acid- DNA *Chromosomes- Thread-like stuctures made of DNA; humans 23 pairs of Chromosomes. *Genes- segmnets of chromsomes that carry genetic code for a certain protein *Ribonucleic- a single-stranded molecule that transports DNA info to the nucleus to the cytoplasm of the cell. |
|
|
Ribosomes
|
Organelles That use the info in RNA to create Proteins
|
|
|
Endoplasmic Reticulum (ER)
|
a network tubules in the cytoplasm that packages and ships the protein created by Ribosomes to different areas of the cell.
*Rough ER-ER that has Ribosomes bound to it surface, produce the proteins that are secreted by the cell *Smooth ER-ER that lacks Ribosomes bound to it surface,many enzymes that synthesize important lipids and steroids are contained here |
|
|
Mitochondria
|
Organelles that tranform fats into energy by synthesize it into adenosine triphosphate (ATP) This molecule is then broken down(burnt) by the cell as energy; Powerhouse of the cell
|
|
|
Lysosome
|
A packet of digestive enzymes that digest cells and organelles that are foregin or damaged
|
|
|
Centrioles
|
small, spindle like organelles that supervise cell divison
|
|
|
Cilia
|
hair-like protrusion from the cell membrane used for moving substance
|
|
|
Flagellum
|
a tail-like projection on the cell membrane used for motility
|
|
|
Mitosis
|
the process by which one cell divides into two identical cells
|
|
|
Tonicity
|
a measure of strength of a concentration of a solution
|
|
|
Hypertonic
|
a solution with higher cocentration of solute
|
|
|
Isotonic
|
a solution with same cocentration of solute
|
|
|
Hypotonic
|
a solution with higher cocentration of solute
|
