Phospholipid |
-Make up bi-layer of phospholipids in cell membrane -Two parts: •Hydrophilic/polar head (attracted to water and charged) •Hydrophobic/nonpolar tail (afraid of water and not charged) |
|
|
Bilayer |
Phospholipids arranged into two layers (in a cell membrane) |
|
|
Osmosis |
Diffusion of water through selectively permeable membrane |
|
|
Diffusion |
Transport of substances |
|
|
Concentration |
Mass of solute in a given volume of solution (mass/volume) |
|
|
Permeability |
Ability (or lack thereof) for molecules to cross membrane |
|
|
Hypotonic |
The solution with higher concentration of water (out of two) |
|
|
Hypertonic |
The solution with the lesser concentration of water (out of two) |
|
|
Isotonic |
Concentration of two solutions is the same |
|
|
Prokaryotes |
Cell without nucleus or membrane-bound organelles; classified into bacteria and archaebacteria |
|
|
Eukaryote |
Cells with a nucleus and membrane-bound organelles; classified as animals, plants, fungi, and protists |
|
|
Virus |
Nonliving molecule because they are not made up of cells, cannot live independently (live off of human cells), cannot reproduce independently, do not require energy or food, and do not grow, develop, or move
Consist of nucleus acid and a protein coat (capsid) |
|
|
Organelle |
Structure found inside a cell that performs a certain function |
|
|
Equilibrium |
When concentration of a solute is the same throughout a solution |
|
|
Endosymbiotic |
Situation in which one of the symbiotic organisms lives inside the other |
|
|
Stem cells |
Cells that can differentiate and become specialized for a specific structure/function during multicellular development from cell differentiation (aka cell specialization)
Have the abilities to: -Divide and renew themselves for long periods of time -Remain undifferentiated in form -Develop (or differentiate) into another type of cell |
|
|
Homeostasis |
Maintenance of internal environment in spite of changes in external environment |
|
|
Capsid |
Protein coat of a virus |
|
|
Differentiation |
Process in which cell becomes specialized for specific structure of function during multicellular development |
