Cell Transport Concept

What type of transport is pictured here?

• exocytosis

• endocytosis

• facilitated diffusion

• diffusion

What type of transport is pictured here?

• endocytosis

• exocytosis

• facilitated diffusion

• osmosis

What type of transport is pictured here?

• endocytosis

• exocytosis

• diffusion

• osmosis

What type of transport is this? Be specific:

When an amoeba captures bacteria.

• phagocytosis

• exocytosis

• pinocytosis

• facilitated diffusion

What type of transport is this? Be specific:

When oxygen passes straight through a cell membrane moving from high concentration to low.

• facilitated diffusion

• active transport

• osmosis

• diffusion

Solutes (dissolved particles) are at equilibrium (the concentration is the same) inside and outside the cell.

• solution must be hypertonic

• solution must be hypotonic

• solution must be isotonic

When there is a low concentration of solutes outside the cell. The solution is:

• hypertonic

• isotonic

• hypotonic

A test tube of water containing 0.8 mg of salts, holding a cell whose cytoplasm has a concentration of 0.02 mg salts. The solution is:

• hypertonic

• hypotonic

• isotonic

Why is the cell membrane selectively permeable?

• large, polar molecules that are soluble in water can pass easily

• small, nonpolar molecules that are soluble in lipids pass easily

• there is a doorman that lets molecules cross

• only water can cross the cell membrane

If a cell expends energy (ATP) to bring materials from the outside to the inside, what is the process called?

• exocytosis

• facilitated diffusion

• endocytosis

• osmosis
