photosynthesis

What is photosynthesis?

• The process of breaking down glucose to release energy

• The breakdown of oxygen to produce energy

• The process of converting light energy into chemical energy in the form of glucose

• The conversion of water into oxygen and carbon dioxide

How is photosynthesis related to light, energy, and life?

• It is a process that converts sunlight into electricity for living organisms.

• It is the process by which light energy is converted into chemical energy for the sustenance of living organisms.

• It is the process by which living organisms produce light energy for survival.

• It is a mechanism that transforms heat energy into usable energy for life processes.

What is the primary source of energy for photosynthesis?

• Heat
  

• Electricity

• Chemicals

• Light

How do plants capture light energy during photosynthesis?

• Through the absorption of

• By inhaling carbon dioxide from the air

• Via the action of chlorophyll in chloroplasts

• By extracting sunlight through their roots

In which organelle does photosynthesis take place in plant cells?

• Nucleus

• Mitochondrion

• Chloroplast

• Endoplasmic reticulum

How do light-dependent reactions contribute to the overall process of photosynthesis?

• Light-dependent reactions produce glucose directly
  

• They release oxygen as a byproduct

• Light-dependent reactions provide the energy to drive the Calvin cycle

• They convert carbon dioxide into water

How is ATP produced during the light-dependent reactions?

• Direct synthesis from carbon dioxide

• Direct absorption from sunlight

• Indirect synthesis through the electron transport chain

• Indirect absorption from water

What is the significance of the Calvin cycle in photosynthesis?

• It captures light energy and converts it into chemical energy

• It synthesizes glucose from carbon dioxide

• It regulates the opening and closing of stomata

• It produces oxygen as a byproduct

How is carbon dioxide used by plants in photosynthesis?

• Carbon dioxide is a byproduct of photosynthesis

• Carbon dioxide is released into the atmosphere during photosynthesis

• Carbon dioxide serves as a source of energy for plants

• Carbon dioxide is combined with water to produce glucose and oxygen

What effect does light intensity have on photosynthesis rate?

• Lower light intensity always results in higher photosynthesis rates

• Light intensity has no impact on photosynthesis rate

• Photosynthesis rate decreases with increasing light intensity

• Higher light intensity increases photosynthesis rate until a maximum is reached
