Photosynthesis Concepts and Processes

The video provides an overview of photosynthesis, focusing on how sunlight powers the process. It explains the role of visible light, the separation of colors through prisms, and how different colors are absorbed or reflected by objects. The video details the photosynthesis process, including the light-dependent reactions and the Calvin cycle, highlighting the creation of glucose and oxygen. It also covers how plants use glucose for energy through cellular respiration.

What type of light from the sun is primarily responsible for powering photosynthesis?

• Microwave light

• Ultraviolet light

• Visible light

• Infrared light

Why do leaves appear green to our eyes?

• They absorb all colors equally.

• They reflect all colors equally.

• They reflect green light and absorb other colors.

• They absorb green light and reflect other colors.

Which colors of light are most effective for photosynthesis?

• Yellow and indigo

• Green and yellow

• Red and blue

• Orange and violet

What are the main products of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Oxygen and nitrogen

• Glucose and carbon dioxide

Which organisms, besides plants, are capable of photosynthesis?

• All living organisms

• Fungi and animals

• Algae, phytoplankton, and some bacteria

• Only plants

Where do the light-dependent reactions of photosynthesis occur?

• In the cytoplasm

• In the mitochondria

• In the thylakoid membranes

• In the stroma

What is the role of NADPH in photosynthesis?

• It releases oxygen.

• It carries hydrogen atoms.

• It stores glucose.

• It absorbs sunlight.

What is the main purpose of glucose produced in photosynthesis?

• To be converted into oxygen

• To be used as a pigment

• To be used in cellular respiration

• To be stored as waste

What happens to glucose after it is produced in photosynthesis?

• It is released as waste.

• It is immediately converted to oxygen.

• It is stored in the chloroplast.

• It is used in cellular respiration in mitochondria.

What is the relationship between photosynthesis and cellular respiration?

• Cellular respiration produces glucose, which is used in photosynthesis to make ATP.

• Photosynthesis and cellular respiration are unrelated processes.

• Both processes occur in the mitochondria.

• Photosynthesis produces glucose, which is used in cellular respiration to make ATP.
