Cell Transportation

The process by which molecules move from an area of higher concentration to an area of lower concentration.

• Diffusion

• Osmosis

• Selective Permeable

The diffusion of water molecules across a selective permeable membrane.

• Diffusion

• Osmosis

• Selective Permeable

A property of cell membranes that allows some substances to pass across it, while others cannot.

• Cell transportation

• Selective permeable       

• Passive transport

The movement of dissolved material across a selective permeable membrane without using cellular energy.

• Active Transport

• Cell transportation    

• Passive transport

Match the following

• the movement of water across a cell membrane

• active transport

• requires energy, moves from low to high concentration

• osmosis

• uses a channel protein to move large molecules across a membrane

• Passive transport

• does not require energy, moves from high to low concentration

• facilitated diffusion

Diffusion is the net​ (a)   of ​ (b)   ​ from a region of ​ (c)   concentration to a region of ​ (d)   concentration.

• movement

• particles

• higher

• lower

• water

​ ​ (a)   does NOT require energy.

• passive transport

• active transport

• endocystosis

• exocytocisi

Diffusion is the movement of molecules from a ​ (a)   concentration to a ​ (b)   concentration until both sides are ​ (c)   .

• higher

• lower

• equal

Examples of this would be diffusion, (41)​ (a)   (the diffusion of water), and facilitated diffusion. Active transport requires

the use of energy because it is the movement of molecules from a (42)​ (b)   to

(43)​ (c)   concentration (or (44)​ (d)   the concentration gradient).

• Osmosis

• Active Transport

• endocytosis

• exocytosis

• low

• high

• against

Answer explanation

Osmosis is the correct choice as it refers to the diffusion of water. 'Low' and 'high' are accurate for the blanks 39 and 40 respectively, indicating movement against the concentration gradient.

Which of the following are types of passive transport? (Select all that apply.)

• Diffusion

• Osmosis

• facilitated diffusion

• active transport
