Photosynthesis

Which organelle is responsible making food (glucose) using sunlight?

• cell membrane

• nucleus

• chloroplast

• mitochondria

Select all that are products of photosynthesis.

• water

• carbon dioxide

• oxygen

• sunlight (light energy)

• glucose (sugar/food)

Which organelle stores water for use in photosynthesis?

• chloroplast

• cell membrane

• vacuole

• nucleus

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

How does carbon dioxide get into the leaves of a plant?

• it's absorbed by the roots

• it's made in a chemical reaction in the stem

• it enters through the stomata

• it goes through the flowers

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 of the following is the correct equation for photosynthesis?

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

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

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

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

Which organisms perform photosynthesis?

• autotrophs

• heterotrophs
