|
Nucleus |
Contains DNA of cell |
|
|
Chromosomes |
Organized masses of DNA in the nucleus. Contain all the material for regeneration of the cell, instructions of cell function as well. |
|
|
Ribosomes |
Read RNA that is made in the nucleus and translates the genetic instructions to produce proteins.
2 types: Bound ribosomes: bound to the endoplasmic reticulum Free ribosomes: free in the cytoplasm
Two types interchangeable |
|
|
Endoplasmic reticulum |
Membranous organelle attached to nuclear membrane.
Rough ER: covered with ribosomes. Responsible for protein synthesis and membrane productions.
Smooth ER: lacks ribosomes; detoxification and metabolism of multiple molecules
|
|
|
Golgi apparatus |
UPS: packaging, processing, shipping organelle. Transports materials from the ER throughout cell. |
|
|
Lysosomes |
Intercellular digestion takes place here. Packed with hydrolytic enzymes. They can hydrolyze proteins, fats, sugars, and nucleus acids. |
|
|
Vacuoles |
Membrane enclosed structure w/ various functions. Many cells through phagocytosis uptake food through the cell membrane creating food vacuole. |
|
|
Mitochondria and chloroplasts |
Produce energy. Mitochondria eukaryotes = aerobic respiration; chloroplasts plants= photosynthesis. |
|
|
Cell membrane |
Most important. Protects, communication, passage of substances into and out of cell. Consists of phospholipid bilayer with proteins, cholesterol, and glycoproteins throughout. Membrane has selective permeability. Many proteins act as transport channels. |
|
|
Centrioles |
Help with cell division ( mitosis & meiosis) |
