Which process requires energy from respiration?

Diffusion

Osmosis

Active transport

Evaporation

Osmosis is the movement of:

Water through a partially permeable membrane from dilute to concentrated solution

Solute from high to low concentration

Water from concentrated to dilute solution

Any molecule through a fully permeable membrane

Which cube has the largest surface area to volume ratio?

4 cm cube

3 cm cube

2 cm cube

1 cm cube

A plant cell placed in concentrated salt solution will become:

Turgid

Plasmolysed

Burst

Unchanged

Which change would decrease the rate of diffusion?

Raising the temperature

Making the membrane thicker

Increasing the surface area

Increasing the concentration gradient

Root hair cells absorb nitrate ions from soil where nitrate concentration is lower than in the cell. This is:

Diffusion

Osmosis

Transpiration

Active transport

Which statement best describes Turgid?

The surface area of an object divided by its volume; smaller objects have a larger ratio.

When a plant cell loses so much water by osmosis that the cytoplasm and membrane pull away from the cell wall.

The net movement of water molecules from a dilute solution (high water potential) to a more concentrated solution (low water potential) through a partially permeable membrane.

Describes a plant cell swollen with water, with its cytoplasm pushing against the cell wall.

Which statement best describes Partially permeable membrane?

The net movement of particles from a region of higher concentration to a region of lower concentration, down a concentration gradient, as a result of random movement.

The difference in concentration of a substance between two regions.

When a plant cell loses so much water by osmosis that the cytoplasm and membrane pull away from the cell wall.

A membrane that lets small molecules such as water pass through but stops larger molecules such as sucrose.

Which statement best describes Surface area to volume ratio?

The net movement of water molecules from a dilute solution (high water potential) to a more concentrated solution (low water potential) through a partially permeable membrane.

Describes a plant cell swollen with water, with its cytoplasm pushing against the cell wall.

A protein in the cell membrane that binds a specific substance and moves it across the membrane.

The surface area of an object divided by its volume; smaller objects have a larger ratio.

Which statement best describes Osmosis?

The net movement of water molecules from a dilute solution (high water potential) to a more concentrated solution (low water potential) through a partially permeable membrane.

The net movement of particles from a region of higher concentration to a region of lower concentration, down a concentration gradient, as a result of random movement.

The movement of substances against a concentration gradient using energy from respiration and carrier proteins in the membrane.

A membrane that lets small molecules such as water pass through but stops larger molecules such as sucrose.
