Digestion in Plants

What is photosynthesis?

• Photosynthesis is the process of converting heat into energy

• Photosynthesis is the process of converting sound waves into energy

• Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose molecules.

• Photosynthesis is the process of converting metals into energy

Which organelle in plant cells is responsible for photosynthesis?

• Nucleus

• Chloroplasts

• Endoplasmic reticulum

• Mitochondria

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions

• Sunlight-dependent reactions and sunlight-independent reactions

• Light-absorbing reactions and light-releasing reactions

• Dark-dependent reactions and dark-independent reactions

What are the reactants of photosynthesis?

• oxygen and glucose

• hydrogen and carbon monoxide

• carbon dioxide and water

• nitrogen and sunlight

What are the products of photosynthesis?

• Protein and lipids

• Water and carbon dioxide

• Starch and nitrogen

• Glucose and oxygen

What is the role of chlorophyll in photosynthesis?

• Chlorophyll absorbs light energy

• Chlorophyll stores water

• Chlorophyll converts carbon dioxide into glucose

• Chlorophyll releases oxygen

How does light intensity affect the rate of photosynthesis?

• Increasing light intensity decreases the rate of photosynthesis

• Light intensity has no effect on the rate of photosynthesis

• Photosynthesis occurs faster in complete darkness

• Light intensity affects the rate of photosynthesis by initially increasing it until a saturation point is reached.

What is the equation for photosynthesis?

• 6CO2 + 6H2O -> C6H12O6 + 6O2

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

• 6CO2 + 6H2O + ATP -> C6H12O6 + 6O2

• 6CO2 + 6H2O + heat energy -> C6H12O6 + 6O2

What is the importance of photosynthesis for plants?

• Plants use photosynthesis to produce sound waves

• Photosynthesis helps plants communicate with each other

• Photosynthesis provides plants with the energy they need to survive and grow.

• Photosynthesis is only important for plants in the winter

How do plants obtain the carbon dioxide needed for photosynthesis?

• By absorbing it from the soil

• Through their roots

• By producing it internally

• Through stomata on their leaves
