|
Active Transport |
Energy Required reprocess by which substances move across the plasma membrane against a concentration gradient. |
|
|
Cell Membrane |
(plasma membrane) Flexible, selectively permeable boundary that helps control what enters and leaves the cell. |
|
|
Cell Wall |
In plants, the rigid barrier that surrounds the outside of the plasma membrane, is made of cellulose, and provides support and protection to the cell. |
|
|
Centriole |
Organelle that plays a role in cell division and is made of microtubules. |
|
|
Chloroplast |
Double membrane organelle that captures light energy and converts it to chemical energy through photosynthesis. |
|
|
Diffusion |
Net movement of particles from an area of higher concentration to an area of lower concentration. |
|
|
Endosymbiosis |
A type of symbiosis in which one organism lives inside the other, the two typically behaving as a single organism. It is believed to be the means by which such organelles as mitochondria and chloroplasts arose within eukaryotic cells. |
|
|
Equilibrium |
A state of rest or balance due to the equal action of opposing forces. |
|
|
Nucleus |
In eukaryotic cells, the central membrane bound organelle that manages cellular functions and contains DNA. |
|
|
Osmosis |
Diffusion of water across a selectively permeable membrane. |
|
|
Passive Transport |
The movement of materials into or out of a cell without the expense of energy. |
|
|
Ribosome |
Simple cell organelle that helps manufacture proteins. |
|
|
Semi-Permeable |
(Selectively permeable)- condition or quality of allowing some, but not all, materials to cords a barrier or membrane. |
|
|
Mitochondria |
Membrane bound organelle that converts fuel into energy that is available to the rest of the cell. |
