Transcript of Cell Transport Concept Map

Cell Transport Concept Map
Diffusion
The movement from high concentration to low concentration.
Osmosis
Diffusion between water through a selective material of the membrane until equilibrium occurs.
Active & Passive Transport
Movement of material against a concentration gradient, which goes low to high. This process requires energy (ATP) as it uses transport proteins. An example is the sodium-potassium pump. While passive does not require energy.
Concentration Gradient
The concentration decrease over a period of time.
Cell Transport
The movement of materials throughout the cell. There are several forms of transportation.
Simple Diffusion
The movement of the particles of materials from high concentration to low concentration, until equilibrium occurs.
Facilitated Diffusion
Selective molecules cross the membrane required to join with a carrier protein.
Solute
Material in a lower concentration.
Solvent
Material in higher concentration.
Isotonic Solution
concentration of solutes is equal in and outside of the cell. Since there is not net movement of water, the cell maintains it's shape.
Hypotonic Solution
Concentration of solutes is lower outside the cell.
This is where water enter water cells. With animal cells the cell swells, as where plant cells the cell wall prevents breaking. (T.P.) Protists contractile vacuoles.
Hypertonic Solution
Concentration of solutes is higher outside the cell. This is where water exits the cell and pasmolysis the Cytoplasm shrinks.

Bulk Transport
Movement of particles into or out of a cell without passing through the cell membrane, which requires energy.

Endocytosis
Bulk transport of material into a cell, which is food and water. Food and water are necessities, so obviously these would move in the cell.
Exocytosis
Bulk transport of materials out of a cell, such as waste and hormones. For example, the materials move out rather than in when it gets crowded.

Phagocytosis
Moves solids or large particles in.

Pinocytosis
Moves in liquids or very small particles.

Concentration Gradient
Concentration Gradient, which is the decrease of concentration over a period of time gradually.
Active Transport
Move against the concentration gradient, which is low to high. This uses transport proteins to join with.
Facilitated Diffusion
Moves with the concentration gradient, which is high to low. This doesn't require energy.
