Chapter 3 Flashcards
1
Q
3 main regions of a cell
A
- Cell Membrane
- Nucleus
- Cytoplasm
2
Q
Osmosis
A
- Net movement of water through a permeable membrane
- From high to low
- Diffusion of water
3
Q
Tonicity
A
-Conditions that cause water to move across the membrane
4
Q
Isotonic Solution
A
- Both solutions have the same solute and water concentration
- Equal
- No gain or loss
5
Q
Hypertonic Solution
A
- higher solute concentration
- Net loss of water
- Water leaves cell
6
Q
Hypotonic
A
- Lower solute concentration
- Net gain of water
- Water enters cell
7
Q
Active Transport
A
- Requires a carrier
- Requires energy (ATP)
8
Q
Endocytosis
A
-Bringing materials into a cell
9
Q
Exocytosis
A
-Movement of materials out of a cell
10
Q
Phagocytosis
A
-Process where large particles are engulfed by the cell
11
Q
Pinocytosis
A
- “cell drinking”
- Process where droplets of liquids are engulfed by cell
12
Q
Diffusion
A
-Movement of particles from high concentration to low
13
Q
Facilitated Diffusion
A
- Integral Proteins are used to transport large molecules across membrane
- High to Low
14
Q
Cancer
A
-A group of diseases in which there is uncontrolled mitosis (apoptosis)
15
Q
Apoptosis
A
Programmed Cell Death
