Diffusion
|
Movement of a substance from an area of hight concentration to an area of low concentration.
|
Osmosis
|
Diffusion of water or other solvent through a cell membrane
|
Isotonic
|
Water concentration inside the cell is the same outside of the cell.
|
Mitochondria
|
Powerhouse...breaks down food for energy.
|
Active transport
|
Larger molecules require energy to pass through a membrane.
|
Passive transport
|
The movement of a chemical substance across a cell membrane without energy by the cell, as in diffusion.
|
Hypertonic
|
Water concentration inside the cell is MORE than water concentration outside the cell. Cell will burst, (lyse)
|
Hypotonic
|
Water concentration inside the cell is less than concentration outside the cell.
|
Endocytosis
|
When materials enter the cell.
|
Exocytosis
|
More large molecules out of cell (waste)
|
Phagocytosis
|
Cell eating (takes in food)
|
Pincocytosis
|
Cell drinks
|
Selectively permeable
|
Allows some materials to pass but not others.
|
Photosynthesis
|
Means to make with light.
photosynthesis occurs in chloroplasts (leaves)
Chloroplasts contain chlorophyll.
chlorophyll traps sun light energy and combines CO2 w/ H20 to make 602+C6H12O6
|
Respiration
|
Occurs in mitochondria
mitochondria uses O2to break down C6H12O6 to make energy. CO2 and H2O as a waste product.
