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)

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 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 organisms perform Photosynthesis?

• Only Autotrophs

• Only Heterotrophs

• Autotrophs and Heterotrophs

Which of the following is an example of an AUTOTROPH?

• Appletree

• Dog

• Mushroom

• Human

What is the green pigment that "traps" sunlight?

• Chlorophyll

• Chloroplasts

• Photosynthesis

• ATP
