Active Transport and Root Hair Cells Quiz

What is the main difference between diffusion and active transport?

• Diffusion is a passive process, while active transport requires energy.

• Diffusion occurs only in plant cells, while active transport occurs in animal cells.

• Diffusion moves substances against their concentration gradient, while active transport moves them down the gradient.

• Diffusion requires energy, while active transport does not.

Which of the following is necessary for active transport to occur?

• A large surface area

• Special proteins in the cell membrane

• Chlorophyll

• A concentration gradient

Where does the energy for active transport primarily come from?

• Photosynthesis

• Cellular respiration

• Diffusion

• Osmosis

What adaptation helps root hair cells absorb more mineral ions?

• Having a thick cell wall

• Being located deep in the soil

• Having a large surface area

• Producing chlorophyll

Why can't root hair cells absorb minerals by diffusion?

• The minerals are at a higher concentration inside the cell than in the soil.

• The minerals are too large to pass through the cell membrane.

• The soil is too dry for diffusion to occur.

• The minerals are not soluble in water.
