One possible conclusion that can be drawn about the activity of this cell is that

• more active transport occurs

• no active transport occurs

• the cell uses some of the extra mitochondria to make food

• the cell is a plant cell since it has a cell wall

Which description best identifies this type of cellular transport?

• Active transport, because energy is being used to move molecules against the concentration gradient

• Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

• Osmosis, because energy is not being used to move molecules with the concentration gradient

• Endocytosis, because energy is not being used to move molecules against the concentration gradient

Match the following vocabulary terms and definitions.

• Isotonic

• Same concentration; the solution and cell have equal concentration of solutes (particles), so water moves equally between the cell and solution.

• Hypertonic

• Low concentration; the solution has less solutes than the cell, causing water to move into the cell and out of the solution.

• Hypotonic

• High concentration; the solution has more solutes than the cell, causing water to move out of the cell and into the solution.

​ (a)   brings glucose into cells.

• Insulin

• Glucagon

• Glycogen

Which of the following statements best describes the general direction of diffusion across the membrane?

• sugar would diffuse into the cell

• water would diffuse into the cell

• there would be no movement of water

• the sugar molecule would not move

Active transport is defined as the movement of

• material from high to low concentration using energy

• material from low to high without the use of energy

• water from high to low concentration

• material from low to high with the use of energy
