Botany: Photosynthesis Process

What is the primary pigment involved in photosynthesis?

• Chlorophyll

• Melanin

• Carotene

• Xanthophyll

Where does photosynthesis take place in a plant cell?

• Chloroplasts

• Endoplasmic reticulum

• Mitochondria

• Nucleus

What are the two main stages of photosynthesis?

• Light-dependent reactions and light-independent reactions

• Dark-dependent reactions and dark-independent reactions

• Sun-dependent reactions and sun-independent reactions

• Light reactions and heavy reactions

What is the role of chlorophyll in photosynthesis?

• Chlorophyll converts water into oxygen in photosynthesis.

• Chlorophyll absorbs carbon dioxide in photosynthesis.

• Chlorophyll regulates temperature in photosynthesis.

• Chlorophyll helps capture light energy for photosynthesis.

What are the products of the light-dependent reactions in photosynthesis?

• Carbon Dioxide and Water

• Chlorophyll and Sunlight

• ATP and NADPH

• Glucose and Oxygen

What is the Calvin cycle and what is its significance in photosynthesis?

• The Calvin cycle is only significant in the initial stages of photosynthesis.

• The Calvin cycle is responsible for producing oxygen in photosynthesis.

• The Calvin cycle is not involved in the conversion of carbon dioxide to glucose.

• The Calvin cycle is significant in photosynthesis as it is responsible for producing glucose, which is the main source of energy for plants and other organisms. It also helps in the recycling of RuBP, ensuring the continuous flow of carbon through the cycle.

How does the process of photosynthesis contribute to the oxygen cycle?

• Photosynthesis contributes to the oxygen cycle by absorbing oxygen from the atmosphere.

• Photosynthesis contributes to the oxygen cycle by releasing oxygen as a byproduct.

• Photosynthesis contributes to the oxygen cycle by reducing the amount of oxygen in the environment.

• Photosynthesis contributes to the oxygen cycle by producing carbon dioxide.

Explain the concept of photosynthetic efficiency and its importance in plant growth.

• Photosynthetic efficiency is not related to plant growth

• Photosynthetic efficiency is essential for plant growth as it supplies the energy needed for metabolic processes.

• Photosynthetic efficiency has no impact on metabolic processes

• Photosynthetic efficiency is only important for animal growth
