Obtaining and Removing Materials

This organelle is selectively permeable, meaning it can allow certain substances to pass through.

• Chloroplast

• Cell Membrane

• Mitochondria

• Nucleus

_________ is a type of passive transport where materials move across a membrane without the use of ATP energy.

• Diffusion

• Osmosis

• Active Transport

• Protein doorways

___________ is a type of passive transport where water passes across the cell membrane.

• Diffusion

• Active Transport

• Facilitated diffusion

• Osmosis

Which of the following is NOT a way cellular materials move?

• Passive transport

• Active transport

• Endo/Exocytosis

• Oxygen transport

T/F: In passive transport, particles always move from areas of high concentration to areas of low concentration.

• True

• False

T/F: Equilibrium is met when the concentration is even on both sides of the membrane.

• True

• False

T/F: Passive transport requires the use of ATP energy to move particles.

• True

• False

T/F: Active transport moves against the concentration gradient.

• True

• Fasle

T/F: Diffusion will continue until concentrations are unevenly distributed.

• True

• False

How can temperature affect the rate of diffusion?

• Higher temperature = speeds up, colder temperature = slows down

• Colder temperature = speeds up, higher temperature = slows down
