Cell Transport

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

• Active Transport

• Diffusion

• Facilitated Diffusion

• Exocytosis

This picture represents what type of cell transport?

• Passive Transport

• Exocytosis

• Osmosis

• Endocytosis

Which is true about active transport?

• It requires energy

• It moves substances down the concentration gradient

• It does not require energy

• It moves substances from high to low concentration

A cell in an isotonic solution will:

• Swell

• Shrink

• Stay the same size

• Shrink and then swell

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

• Endocytosis

• Osmosis

• Exocytosis

• Active Transport

Identify the specific type of transport illustrated in the picture.

• Diffusion

• Osmosis

• Active Transport

• Facilitated Diffusion

What does a cell need to transport particles by active transport?

• Protein Channels

• Energy

• Vacuoles

• A cell wall

The cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration is called:

• Diffusion

• Osmosis

• Active Transport

• Passive Transport

What type of solution causes the blood cells to swell and burst? Net movement of water molecules into the cell.

• Isotonic

• Hypertonic

• Hypotonic

• Homeostasis

Large particles, cell products, or waste are released to the outside of the cell through:

• Endocytosis

• Osmosis

• Diffusion

• Exocytosis
