organelle functions PART 2
cell environment
Definitions
100
Has NO nucleus
Prokaryotic
100
Store & protects DNA; manages or controls all the cell functions in a eukaryotic cell
nucleus
100
Contains chlorophyll, a green pigment that traps energy
chloroplast
100
solution that has same amount of solute as in cell
Isotonic
100
Movement of materials down the concentration gradient
Passive Transport
200
bacteria are an example
prokaryotic
200
Composed of a phospholipid bilayer, membrane surrounding cell
cell membrane
200
Surrounds the cell membrane, protects and supports the cell (plant cells)
Cell wall
200
solution that has less solute than in cell; cell gets bigger
hypotonic
200
Movement of materials against the concentration gradient (requires energy)
Active Transport
300
fungi are an example
Eukaryotic
300
Produces a usable form of energy for the cell
mitochondria
300
Packages proteins for transport out of the cell
Golgi apparatus (body or complex)
300
solution with more solute than in cell; cell shrinks
hypertonic
300
the process by which molecules spread from areas of high concentration, to areas of low concentration (no energy)
diffusion
400
have organelles
Eukaryotic
400
Transports proteins and other material within the cell
Endoplasmic Reticulum
400
The sites of protein synthesis
ribosome
400
where does the water go? solution: 65% water & 35% salt cell: 75% water & 25% salt
OUT of the cell
400
The diffusion of water
osmosis
500
has cell membrane
Tricky! BOTH have cell membranes!
500
Site where ribosomes are made; inside nucleus
nucleolus
500
Digests excess or worn-out cell parts, food particles
lysosomes
500
where does the water go? solution: 38% salt cell: 42% salt
INTO the cell
500
Allows some, but not all materials to cross the membrane
selective permeability (semipermeable)
