Chapter 8 Biology Flashcards
Brownies motion
The random constant movement of particle in liquid or air
Passive transport
The movement of substances across the cell membrane along their concentration gradient doesn’t require an input of energy
Diffusion
The net movement of particles from an area of high to low concentration
Osmosis
The movement of water molecules across a membrane from an area of higher concentration of water to an area of lower concentration of water
Isotonic
Having the same concentration of solutes
Equilibrium
A state in an isolated chemical system in which there are no measurable changes over time
Endocytosis
In / pinches into vesicle
Exocytosis
Out/ surrounds vacuole or vesicle
Liposomes
Artificial vesicles that have been developed to deposit medications inside cells
Macrophage
A large cell that defends the body against invading diseases
