Organelles
Produces energy for the cell.
Mitochondria
What is the plasma membrane composed of?
A Phospholipid bilayer
What is the diffusion of water called?
Osmosis
What are pumps?
They are carrier proteins that aid in active transport
Studded with Ribosomes and synthesizes proteins.
Rough ER
Structure in the cell membrane that contributes to the fluidity of the cell.
cholesterol
What is the movement of molecules from high concentration to low concentration called?
What is diffusion?
Found in all Eukaryotes and stores Chromatin.
Nucleus
What is the key property of the cell membrane?
Selective permeability
What is the condition where there is continuous movement but no overall change?
Dynamic Equilibrium
A semifluid material that is found within the plasma membrane.
Cytoplasm
These act as channels to allow molecules to move in and out of the cell.
What are transport proteins?
The two organelles that are found in plant cells, but not in an animals cell?
cell wall and chloroplast.
What is the orientation of the phospholipid bilayer?
Polar heads face outward and nonpolar heads face inward.
What types of molecules move easily through a cell membrane?
Small nonpolar molecules.
During active transport molecules move in this direction across the cell membrane.
What is from low concentration to high concentration?
