Which plant LACKS CO2 storage method and can't prevent damage from photorespiration?

• C3

• C4

• CAM

Plants that temporarily separate the light and dark reactions by using daytime and nighttime are:

• C3 plants

• C4 plants

• CAM plants

What does a C4 plant do to minimize photorespiration?

• Physically separates the light and dark reactions

• Doesn't perform the dark reactions

• Never opens its stomata

• Uses oxygen to create carbon dioxide

Why does photorespiration occur?

• stomata are closed and CO2 levels are too low.

• stomata are closed and O2 levels are too low.

• stomata are open and too much water is leaving the plant

• stomata are open and the plant receives too much CO2

Transpiration is

• the movement of water through a plant from the roots up the stem
• the loss of water from the leaves of a plant by the process of evaporation
• the flow of water into plant roots by osmosis from the soil
• the process of minerals and sugars moving through plant veins

The theory of Endosymbiosis explains...

• The origin of eukaryotes

• How species develop

• How bacteria evolved

• Why cells rely on one another

Endosymbiotic theory states that chloroplasts and mitochondria were once what?

• Bacteria engulfed by larger cells

• Amino acids

• Large eukaryotes

• Algae

Plants can close their stomata when the temperature is hot

• To prevent water loss

• To prevent loss of oxygen

• To prevent loss of carbon dioxide

• To bring in more carbon dioxide

Which of the following is a way to increase the rate of photosynthesis?

• Increase oxygen levels

• Decrease CO2 levels

• Increase light intensity

• Decrease water level

Which of the following is true of the Calvin Cycle?

• carbon dioxide and energy (ATP and NADPH) are used to make organic compounds

• energy is absorbed from sunlight and converted to chemical energy stored in ATP and NADPH

• Occurs in the thylakoid

• Occurs in the cytoplasm
