Photosynthesis

1.

What are the reactants of cellular respiration in plants?

• carbon dioxide and water

• glucose and carbon dioxide

• the reactants of the electron transport chain

• oxygen and glucose

which of the following is a reactant to photosynthesis?

• Oxygen

• Carbohydrates

• Glucose

• Water

Select all that are raw materials for Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

Select all that are products of Photosynthesis.

• Water

• Carbon Dioxide

• Oxygen

• Sunlight (Light Energy)

• Glucose (Sugar/food)

How does most of the water needed by the plant get into its leaves?

• It enters through the stomata

• The roots absorb it and then it travels up the stem

• It's made during a chemical reaction in the leaf

• The flowers capture water and deliver it to the leaves

Why do plants conduct photosynthesis?

• To make light
• To make mitochondria
• To make glucose
• To release carbon dioxide

Which of these conditions would decrease the rate of photosynthesis in a plant?

• Above average precipitation
• Changing the daylight hours from 14 hrs to 10 hrs
• Changing the CO₂ concentration from 380 ppm to 410 ppm
• All of these choices

Which choice correctly shows the gases that enter and exit plants during photosynthesis?

• Enter: Oxygen
  Exit: Carbon dioxide
• Enter: Water vapor
  Exit: Glucose
• Enter: Carbon dioxide
  Exit: Oxygen
• Enter: Light
  Exit: Water vapor

Which of the following is the correct equation for PHOTOSYNTHESIS?

• light + carbon dioxide + water --> glucose + oxygen

• carbon dioxide + sugar + water --> oxygen + light

• oxygen + light + water --> carbon dioxide + sugar

• carbon dioxide + oxygen + water --> Light+ Sugar

Which organisms perform Photosynthesis?

• Only Autotrophs
• Only Heterotrophs
• Autotrophs and Heterotrophs
