Bio 105 Lab Lecture 5 Flashcards
Liquid in which a substance is being dissolved inside of
Solvent
Substance that is being dissolved inside another substance
Solute
The final product of both a solute and a solvent
Solution
The movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is achieved
Diffusion
Factors that can effect the rate of change pertaining to Diffusion (Hint: C - T - T - S)
Concentration
Temperature
Time
Size
A layer that only certain molecules can pass through
Semi-Permeable Membrane
Simple diffusion of water
Osmosis
The relative concentration of solutes between solutions
Tonicity
Relative to a cell membrane, when a solution has a higher concentration of solute outside of the cell vs inside the cell
Hypertonic
Relative to a cell membrane, when a solution has a higher concentration of solute inside of the cell vs outside the cell
Hypotonic
Relative to a cell membrane, when a solution has an equal concentration of solute both inside and outside of a cell
Isotonic
When an animal cell bursts from absorbing too much water in a hypotonic solution
Lysis
When a plant cell is in a hypotonic solution (Its preferred state)
Turgid
An animal cell bursts in a hypotonic solution while a plant cell does not. What prevents the plant cell from bursting?
The Cell Wall
What is the preferred solution for an animal cell to exist in?
Isotonic Solution
