Active Transport and Root Hair Cells Quiz

What is diffusion?

• The process by which substances move down their concentration gradient

• The movement of molecules against their concentration gradient

• The process that requires energy from cellular respiration

• The movement of molecules across a cell membrane

What is the main difference between diffusion and active transport?

• Diffusion always takes place across a membrane, while active transport does not

• Diffusion moves molecules from a region of lower concentration to a region of higher concentration, while active transport moves molecules from a region of higher concentration to a region of lower concentration

• Diffusion is an active process, while active transport is a passive process

• Diffusion requires energy from the cell, while active transport is a passive process

Where does the energy for active transport come from?

• Root hair cells

• Nitrates

• Mitochondria

• Chlorophyll

What is the role of root hair cells in plants?

• To break down glucose

• To absorb water and mineral ions

• To produce proteins

• To store energy in ATP

What adaptation do root hair cells have to help with absorption?

• Long hair-like protrusions

• Large surface area and lots of mitochondria

• Special proteins in the membrane

• Energy from cellular respiration

What is the function of mitochondria in active transport?

• To release energy from glucose

• To produce chlorophyll

• To absorb mineral ions

• To store energy in ATP

What do root hair cells use to absorb mineral ions?

• Osmosis

• Passive transport

• Diffusion

• Active transport

What is the energy storage molecule in cellular respiration?

• Glucose

• Nitrates

• Chlorophyll

• ATP

What is the process responsible for all of the energy that the cell uses?

• Cellular respiration

• Osmosis

• Active transport

• Diffusion

What is the source of energy for active transport in root hair cells?

• Fermentation

• Photosynthesis

• Solar respiration

• Glycolysis
