Which of the following is an example of passive transport?

• Endocytosis

• Exocytosis

• Diffusion

• Active transport

Diffusion is the movement of molecules:

• from an area of low concentration to an area of high concentration

• against the concentration gradient

• from an area of high concentration to an area of low concentration

• with the help of transport proteins

Osmosis is the diffusion of:

• water molecules

• oxygen molecules

• glucose molecules

• carbon dioxide molecules

Which term refers to a solution with a higher solute concentration compared to another solution?

• Hypotonic

• Hypertonic

• Isotonic

• Concentrated

Active transport requires:

• energy

• transport proteins

• a concentration gradient

• a semipermeable membrane

Which of the following processes requires energy?

• Diffusion

• Osmosis

• Exocytosis

• Facilitated diffusion

Transport proteins in the cell membrane:

• help maintain cell shape

• facilitate the movement of substances across the membrane

• produce energy for the cell

• store genetic information

Which process involves the cell engulfing substances by surrounding them with the cell membrane?

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

Which of the following is an example of exocytosis?

• A cell taking in nutrients
