• Nucleus

• Chloroplast

• Mitochondria

Select all that are products (outputs) of Photosynthesis.

• Water

• Carbon Dioxide

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 perform photosynthesis?

• To make light

• To make mitochondria

• To transform light energy into chemical energy (sugar)

• To release carbon dioxide

What major energy transformation occurs during photosynthesis?

• Thermal --> Chemical
• Kinetic --> Radiant
• Chemical --> Radiant
• Radiant --> Chemical

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
