Photosynthesis Quiz - H

Plants need ________ to conduct photosynthesis

• Oxygen

• Soil

• Carbon dioxide

• Sugar

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 xylem

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

• 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 organelle in the plant cell performs photosynthesis?

• Chloroplast

• Mitochondria

• Nucleus

• Cytoplasm

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

What are the products of photosynthesis (what is made)?

• Glucose and Chlorophyll

• Glucose and Oxygen

• Water and Light

• Carbon dioxide and Water

What is the source of energy for photosynthesis?

• Carbohydrates (chemical energy)

• Light (radiant energy)

• Heat (thermal energy)

• Wind (kinetic energy)

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
