Question 2

Because plants contain both mitochondria and chloroplasts what can they perform?

Answer 2

Photosynthesis and aerobic respiration

Question 3

What is produced during respiration?

Answer 3

carbon dioxide

Question 4

What is consumed during photosynthesis?

Answer 4

carbon dioxide

Question 5

CO2 and water combine to form what?

Answer 5

carbonic acid

Question 6

The more CO2 in the water, what is also produced more?

Answer 6

acid

Question 7

What pH sensitive chemical will we use to indirectly monitor CO2 production/consumption?

Answer 7

Phenol red

Question 8

If CO2 concentration increases the solution will become ..

Answer 8

More acidic, phenol red is yellow in color

Question 9

If CO2 concentration decreases the solution will become…

Answer 9

More basic, phenol red is pink in color

Question 10

Answer 10

red-orange

Question 11

Where does glycolysis occur?

Answer 11

cytoplasm

Question 12

Where does aerobic respiration occur?

Answer 12

mitochondria

Question 13

Where does photosynthesis occur?

Answer 13

Chloroplast

Question 14

placebo

Answer 14

something which has a positive mental effect, but no physical effect. Resembles actual treatment but does not have a physiological effect

Question 15

Define diffusion

Answer 15

movement of molecules from an area of high concentration to an area of low concentration

Question 16

Define semi-permeable membrane

Answer 16

Membrane that allows some things to pass while others cannot

Question 17

Define concentration gradient

Answer 17

difference in the concentration of a substance from one location to another

Question 18

Define osmolarity

Answer 18

the concentration of a solution expressed as the total number of solute particles per liter.

Question 19

Define osmosis

Answer 19

diffusion of water across a selectively permeable membrane

Question 20

Hyper-osmotic/hypertonic

Answer 20

the side of the semi-permeable membrane having higher solute concentration. Water moves toward, solutes move away, from the hyperosmotic side.

Question 21

hypo-osmotic/hypotonic

Answer 21

the side of the semi-permeable membrane having lower solute concentration. Water moves away from, solutes move toward the hyperosmotic side.

Question 22

Iso-osmotic/isotonic

Answer 22

solute concentrations equal on both sides of a semi-permeable membrane.

Question 23

Plasmolysis

Answer 23

The process of water flowing out of cells, causing them to shrink
