Cell transport

What is the movement of substances from a region of higher concentration to a region of lower concentration called?

• Filtration

• Diffusion

• Active transport

• Osmosis

Which of the following is NOT required for diffusion to occur?

• Energy from ATP

• A concentration gradient

• A partially permeable membrane

• A gas or dissolved substance

What role do carrier proteins play in cell transport?

• They facilitate diffusion of specific substances

• They produce energy for transport processes

• They assist in osmosis by moving water molecules

• They help in the active transport of substances

What can cause animal cells to burst?

• Active transport

• Too much water entering the cell

• Lack of water

• Facilitated diffusion

Which process is used by the roots of plants to absorb water?

• Active transport

• Endocytosis

• Diffusion

• Osmosis
