Photosynthesis & Cellular Respiration

What are the 3 reactants of photosynthesis? The reactants are the things needed for photosynthesis to occur.

• oxygen, glucose, sunlight

• sunlight, oxygen, water

• water, oxygen, carbon dioxide

• carbon dioxide, sunlight, water

What pigment captures/absorbs sunlight?

• stomata

• chlorophyll

• chloroplast

• phloem

What is the tiny openings that let in the carbon dioxide needed for photosynthesis?

• stomata

• xylem

• phloem

• chloroplast

What are the 2 products of photosynthesis? The products are the things made in the process of photosynthesis.

• water, sunlight

• glucose, carbon dioxide

• oxygen, glucose

• sunlight, oxygen

What is the main purpose of photosynthesis?

• To make food

• To create energy

• To release oxygen

• To absorb sunlight

Which product is "waste" and mostly released by the producer (plant)?

• oxygen

• carbon dioxide

• sugar

• glucose

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Which organisms perform Photosynthesis?

• hydrogen
• oxygen
• nitrogen
• carbon dioxide

What is photosynthesis?
