________- breakdown dead cells; digests new materials brought in.
New cards
2
Endoplasmic reticulum
________- makes ribosomes ↳ Smooth>- no ribosomes.
New cards
3
Endocytosis
________- The taking in of things into all pinocytosis- taking in of water phagocytosis- taking in of larger molecules receptor- mediated water going in solid particles already deposit formed, closes to form vesicle exocytosis- letting things out.
New cards
4
Cytoskeleton
________- holds everything together.
New cards
5
Membrane Proteins
________ contain primarily our lipids ↳ especially chlorestorol It helps keep shape.
New cards
6
Vacuole
________- storage area for materials /water.
New cards
7
Hypotonic
________- lots of solvent- cell swells- water moves into cell.
New cards
8
Homeostasis
________- the body's ideal equalness.
New cards
9
Chloroplast
________- make sunlight into energy during photosynthesis; contains chlorophyll, giving green color.
New cards
10
Centrioles
________- help divide cell during cellular division
New cards
11
Diffusion
________- the movement of molecules across the membrane in a high>- low concentration gradient; happens easily w small molecules.
New cards
12
Passive Transport
________ does not require ATP energy examples include:- diffusion; facilitated diffusion; osmosis moves from high- low concentration.
New cards
13
Cell membrane
________- forms a barrier between the cytoplasm and the cell's environment semipermeability- allows some things out; not all.
New cards
14
Peripheal Membrane Proteins
________- temporarily on one side; can be easily removed can attach to imp or can stick into small portion- of lipid bilayer; most are hydrophilic.
New cards
15
Phospholipid bilayer
________- the two layers the phospholipids hydrophilic- likes water hydrophobic- hates water.
New cards
16
tail
attracts hydrophobic stuff
New cards
17
cell membrane
controls what goes in/out, support; outside of cell
New cards
18
Prokaroytic
Older No membrane bound organelles Contain only cell wall, cell membrane, and cytoplasm DNA is free floating Ex bacteria and archaea bacteria
New cards
19
Eukaryotic
younger membrane bound organelles DNA Ex plant and animal cells
New cards
20
Active Transport
Requires ATP energy -examples include Endocytosis and exocytosis
New cards
21
diffusion
the movement of molecules across the membrane in a high-> low concentration gradient; happens easily w small molecules
New cards
22
Hypertonic
lots of solute cell shrives-water moves out of cell
New cards
23
isotonic
equal cell remains the same
New cards
24
Negative Feedback
Tying to break what is stoping homeostasis sweating when hot; shivering When cold
New cards
25
Positive feedback
Amplifying whatever is breaking homeostasis ex contractions; ripening in fruit
