Carrier proteins and ion channel proteins are found in the cell membrane and assist particles in moving in and out of the cell without the use of energy. What type of cell transport is this?

• facilitated diffusion

• passive transport

• pumps

• osmosis

A blood cell is placed in a solution. The image shows the results. What type of solution was the cell placed in?

• hypertonic

• hypotonic

• isotonic

• exotonic

The image represents a cell bringing material into the cytoplasm of the cell. This is an example of...

• passive transport

• active transport

• endocytosis

• exocytosis

Match the following

• requires energy, moves from low to high concentration

• osmosis

• the movement of water across a cell membrane

• active transport

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

• facilitated diffusion

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

• Passive transport

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.

A student measures the mass of each of six potato cores and places one core in each of the unknown solutions. After a period of time, the student removes the potato cores and measures the mass of each one. The results are shown in the table. Which statement best describes a conclusion the student can make about the results?

• Solution 1 is hypertonic because water flowed out the cells of the potato.

• Solution 6 is hypertonic because water flowed out of the cells of the potato.

• Solutions 2 and 5 are hypotonic because water entered the cells of the potato.

• Solutions 3 and 4 are isotonic because water flowed equally in and out of the cells of the potato.
