Cell Transport

The movement of substances across cell membranes is crucial for maintaining cellular function and homeostasis. There are two main types of cell transport: passive and active. Passive transport does not require energy and includes processes like osmosis, diffusion, and facilitated diffusion.

Cell
 Transport

Cell Transport

Concentration

Hypotonic
Lower concentration than the area compared
Inside of Chloroplast
Hypertonic
Higher concentration than the area compared
Outside of Chloroplast

Active Transport

Needs protien to transfer molecules
Exocytosis

A process that occurs when a cell moves large materials from inside the cell to the outside of the cell using small spheres of membrane called vesicles

Endocytosis

The process by which cells take in substances from outside of the cell by engulfing them in a vesicle

Pump

Protein= ADT ( Adenosine Tri Phosphate)

Contractile Vacuole

Na+/K+ Pump

Travels from low concentration to low concentration.
Requires Energy

Homeostasis

Equalibriam
Isotonic

Denoting or relating to a solution having the same osmotic pressure as some other solution, especially one in a cell or a body fluid

Same concentration

Passive Trasport

Facilitated Diffusion

Glucose

Requires a channel protien

Glucose carrier protein

High concentration to Low concentration
