Cell Energy

What will happen to an animal cell placed in a salt water solution?

• the cell will shrink

• the cell will burst

• the cell will expand

Why does misting fruits and vegetables with water help them look fresh?

• Vacuoles fill with water due to osmosis.

• Plant cells in a hypotonic solution lose water.

• Plants do not have a rigid cell wall.

What’s the difference between active transport and diffusion?

• active transport helps maintain homeostasis

• active transport requires energy input

• diffusion requires energy input

passive transport; particles move from HIGH to LOW concentration

• diffusion

• active transport

• endocytosis

the amount of a substance in a particular area; amount of solute in a solvent

• concentration

• buoyancy

• viscosity

• pressure

Diffusion of water across a selectively permeable membrane; type of passive transport

• osmosis

• pinocytosis

• endocytosis

• facilitated diffusion

solute dissolved in a solvent

• solution

• colloid

• suspension

• compound

cell takes in large particles by engulfing them; type of active transport

• endocytosis

• osmosis

• diffusion

• pinocytosis

Movement of substances across a plasma membrane against a concentration gradient; requires ATP (energy)

• active transport

• passive transport

• osmosis

• diffusion

What do cells store and release as the main source of chemical energy?

• ATP

• ADP

• MSP

• MVP
