20 Cards in this Set
- Front
- Back
|
Cytoplasm
|
has cytosol - organelles - inclusions - nutrients
|
|
|
Mitochondria
|
has DNA - RNA - produce ATP
|
|
|
Rough Endoplasmic Reticulum
|
covered with ribosomes - membranous tubules - preps protein for transport
|
|
|
Smooth Endoplasmic Reticulum
|
no ribosomes - lipid/steroid synthesis - lipid metabolism - drug detox.
|
|
|
Ribosomes
|
made of protein + rRNA - synthesize protein - in cytosol - some on rER
|
|
|
Golgi Apparatus
|
stacked membranous sacs - modified & pack proteins - packed products leave secretory vesicles
|
|
|
Vacuoles
|
liquid filled cavity - enclosed in single membrane - help digestion, storage, waste
|
|
|
Lysosomes
|
has digestive enzymes - intracellular digestion - dark staining
|
|
|
Peroxisomes
|
look like lysosome (dark staining) - has enzymes to detox toxic substance
|
|
|
Cytoskeleton
|
3 rods for cell support - microtubules, microfilaments, intermediate
|
|
|
Microtubules
|
cylindrical protein tubules - cell support - intracellular movement - cell movement
|
|
|
Microfilaments
|
thin stands of protein - is actin - strengthens cell surface - cell mobility - change cell shape
|
|
|
Centrioles
|
assembles microtubules - separate to form spindles - forms bases for cilia & flagella
|
|
|
Cilia
|
cell extension moves substance on cell surface - composed of microtubules
|
|
|
Flagella
|
long extension used to propel cell itself (sperm)
|
|
|
Nucleus
|
control cellular activity - has nucleoli & chromatin
|
|
|
Nuclear Envelope
|
double membrane surrounds nucleus - outer membrane continuous with - nuclear pores allow permability
|
|
|
Nucleolus
|
dark bodies in nucleus - combin rRNA + proteins forms ribosomes
|
|
|
Chromatin
|
strands of DNA bound to proteins - condense to form chromosomes for cell division
|
|
|
Plasma Membrane
|
semipermeable - controls passages of substances in/out of cell
|
