Cell Transports

Diffusion

the movement of molecules from an area of high concentration to an area of low concentration

Osmosis

the diffusion of water across a membrane

Selectively Permeable

some stuff can pass through it but not others

Equilibrium

when molecules are evenly spread through a space

Passive Transport

Requires no energy. Diffusion, Osmosis, and facilitated diffusion

Facilitated Diffusion

passive transport when molecules move across the cell membrane with the help of specialized membrane protiens

Hypertonic Solution

water moves out of the cell

Hypotonic Solution

water moves into the cell

Isotonic Solution

water goes in both directions

Active Transport

requires the cell to use energy(ATP). Protiens or pumps found in the membrane move materials across

Endocytosis

taking in large molecule

Exocytosis

removing large partials(waste) from the cell, stuff exits the cell

What is phagocystosis

cellular process where cells take large particles from bacteria, like dead cells or debris and brings them inside to digest them to defend cells

What is pinocytosis

type of endocytosis allowing the cell to take in water, nutrients. This is a crucial process for fluid uptake and how cells get nutrients

What is concentration gradient

the difference in the amount of a substance, like molecules or ions between two areas. for example, food dye in water

What is Brownian moiton

the movement of tiny particles in a fluid caused by a collision with smaller, faster moving atoms
