2.D) Movement of substances into and out of
cells
- 3. Active Transport
- goes against concentration gradient
- protien carriers in cell membrane
- protien carriers in cell membrane
- goes against concentration gradient
- Higher/lower concentration gradient
- 1. Diffusion
- cell membrane permeable to a substance
- example oxygen and carbon dioxide
- experiment: ink moving throughout water
- experiment: ink moving throughout water
- example oxygen and carbon dioxide
- cell membrane permeable to a substance
- 2. Osmosis
- diffusion with water molecules
- diluted molecules have more kinetic energy to move
- experiment: pure water against salty water carrots
- experiment: pure water against salty water carrots
- diluted molecules have more kinetic energy to move
- diffusion with water molecules
- 1. Diffusion
- turgid
cells
- cells full of
water
- supports plants
- supports plants
- cells full of
water
- Factors affecting
movment
- 1. surface area : volume
- flatter means more transport
- flatter means more transport
- 2. temperature
- changes rate of movement
- changes rate of movement
- 3. concentration gradient
- higer to lower
- higer to lower
- 1. surface area : volume
