Organelles 1
Rigid, outer layer that protects outside of plant cells.
Cell Wall
Tiny structures inside a cell which carry out specific functions.
Organelle
Contain a nucleus.
Eukaryotic Cells
These types of transport do not require energy.
Passive transport
Solution where water moves into and out of cell at even rates. Why?
isotonic solution - even amount of solute
Protects inside of cell and regulates what enters and leaves the cell.
Cell Membrane
Captures sunlight and converts it into energy in green plants.
Chloroplast
Do not contain a nucleus
Prokaryotic Cells
These types of transport do require energy.
Active transport.
Solution where water is moving to the outside of the cell. Why?
hypertonic - more solutes outside
Stores water - in plant cells.
Vacuole
Site of protein assembly
ribosome
Two differences between plant and animal cells
Cell wall, large central vacuole, lysosomes, etc.
During passive transport, molecules move from a ___ concentration to a _____ concentration.
High to Low
Solution where water is moving into the cell. Why?
Hypotonic - more solutes inside
Organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use
Mitochondria
Breaks down cell parts for digestion.
Lysosome
During active transport, molecules move from a ___ concentration to a _____ concentration.
low to high
Diffusion of water.
Osmosis
This is what happens to an animal cell in each environment...
Hyper: shrivels
Hypo: fills up and lyses
Iso: at equilibrium (happy)
Functions of smooth and rough ER
The smooth ER is involved in lipid synthesis, while the rough ER is involved in protein synthesis.
Collects, modifies, and packages proteins for different jobs then sends them out.
Golgi Apparatus
During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will…
move in opposite directions at the same rate (inside and outside of cell)
Difference between facilitated diffusion and normal diffusion
proteins in facilitated
This is what happens to a plant cell in each environment...
Hyper: shriveled up cell membrane
Hypo: most preferred, cell membrane turgid
Iso: flaccid, a little shriveled
