Diffusion |
The movement of particles from regions of higher density to regions of lower density. |
|
Osmosis |
The diffusion of water through a semipermeable membrane |
|
Passive Transport |
the movement of substances across a cell membrane without the use of energy by the cell |
|
Active Transport |
the movement of substances across the cell membrane that requires the cell to use energy |
|
Endocytosis |
The process by which a cell membrane the surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell |
|
Exocytosis |
The process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane |
|
Photosynthesis |
The process by which plants ,algae , and some bacteria use sunlight , carbon dioxide , and water to make food |
|
Cellular respiration |
The process by which cells use oxygen to produce energy from food |
|
Fermentation |
The breakdown of food without the use of oxygen |
|
Diffusion is the movement of particles from an area of high concentration to an area of low concentration |
4.1 summary |
|
Osmosis is the diffusion of water through a semipermeable membrane |
4.1 summary |
|
Cells move small particles by diffusion , which is an example of passive transport, and by active transport |
4.1 summary |
|
Large particles enter the cell by enocytosis and exit the cell by exocytosis |
4.1 summary |
|
Most of the energy that fuels life processes comes from the sun |
4.2 summary |
|
The sun's energy is converted into food by the process of photosynthesis |
4.2 summary |
|
Cellular respiration breaks down glucose into water, carbon dioxide , and energy |
4.2 summary |
|
Fermentation is a way that cells get energy from their food without using oxygen |
