Unit 2: Cell Process (based on study guide)

Question 1

Does diffusion require added energy?

Answer 1

Yes, because it moves from a high concentration to a low one requiring energy

Question 2

Describe the likely movement of the oxygen molecules. Would they move into or out of the cell membrane?

Answer 2

Depends where there is more oxygen. Molecules like oxygen move naturally from areas of higher concentration to areas of low concentration. It will move into the cell through the membrane to support Cellar Respiration

Question 3

What is Cellular Respiration?

Answer 3

The process by which organisms use oxygen to break down food molecules to get ATP (energy)

Question 4

What is photosynthesis?

Answer 4

The process in which plants make their food

Question 5

What is Cell division?

Answer 5

Division of cell into two daughter cells with the same genetic material.

Question 6

What correctly shows the gases that enter and exit plants during photosynthesis

Answer 6

Enter: Carbon Dioxide
Exit: Oxygen

Question 7

What is the purpose of Cellar Respiration….

Answer 7

Make more ATP

Question 8

What is DIFFUSION?

Answer 8

HIGH—–LOW

Question 9

What is the correct equation for photosynthesis?

Answer 9

CO2+ light+ H20—–O2+Sugar

Question 10

The waste gas given off by cellular respiration is?

Answer 10

Carbon Dioxide

Question 11

What is a recant of cellular respiration?

Answer 11

glucose

Question 12

What is Active tansport?

Answer 12

the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient.

Question 13

What is passive transport?

Answer 13

the fundamental movement of ions and other molecular substances within the cells along the concentration gradient, without any external energy.
