Biology Passive and Active Transport

Which describes an isotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

The movement of materials from an area of low concentration to an area of high concentration would require...

• glucose

• energy (ATP)

• fish

• chips

Which process involves the movement of molecules from high concentration to low concentration?

• Endocytosis

• Active transport

• osmosis

• phagocytosis

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport

• concentration

• diffusion

• equilibrium

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis

• respiration

• diffusion

• osmosis

The movement of molecules from an area of high concentration to an area of low concentration.

• Osmosis

• Respiration

• Diffusion

• Active Transport

Cells use energy to move materials across a membrane (low to high concentration).

• Active transport

• Passive transport

• Diffusion

• Osmosis

A cell membrane has pores that allow certain materials to pass through. This is a type of cell membrane.

• Permeable

• In high concentration

• At equilibrium

• In low concentration

Which describes a hypotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell
