Cellular Transport

Passive transport requires no

• concentration gradients

• osmosis

• motion

• energy

This example of passive transport is the diffusion of water.

• osmosis
• concentration gradient
• isotonic
• facilitated diffusion

This solution has the equal concentrations of water molecules and particles.

• hypertonic
• hypotonic
• isotonic

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole
• nucleus
• cell membrane
• cell wall

Controlling what goes into or out of the cell with the help of energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

This releases substances outside a cell

• endocytosis
• exocytosis
• both

The movement of molecules against a concentration gradient

• simple diffusion
• facilitated diffusion
• active transport
• osmosis

This takes substances into a cell

• endocytosis
• exocytosis
• both

In which solution will water move out of the cell resulting in the cell shriveling up?

• Hypertonic
• Isotonic
• Hypotonic

In which solution will water move into the cell resulting in the cell bursting?

• Hypertonic
• Isotonic
• Hypotonic
