Introduction to Photosynthesis

What is the relationship between Photosynthesis and Cellular Respiration?

• Photosynthesis produces energy, while Cellular Respiration converts energy into glucose.

• Photosynthesis converts carbon dioxide and water into glucose and oxygen, while Cellular Respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

• Photosynthesis and Cellular Respiration are identical processes that occur in plants.

• Photosynthesis occurs in the mitochondria, while Cellular Respiration occurs in the chloroplasts.

What is the Calvin Cycle?

• The Calvin Cycle is a process that occurs in the mitochondria to produce ATP.

• The Calvin Cycle is the second half of photosynthesis that occurs in the stroma of chloroplasts, where carbon dioxide is converted into glucose.

• The Calvin Cycle is a method of cellular respiration that breaks down glucose.

• The Calvin Cycle is a stage of protein synthesis that occurs in the ribosomes.

What is the chemical equation for Photosynthesis?

• 6CO2 + 6H2O + light energy → C6H12O6 + 6O2

• 6O2 + C6H12O6 → 6CO2 + 6H2O + light energy

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• 6H2O + 6CO2 → C6H12O6 + 6O2 + light energy

What is Photosynthesis?

• The process by which plants convert sunlight into heat energy.

• The process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

• The method by which animals produce energy from food.

• The way in which soil absorbs nutrients from the atmosphere.

What role do bacteria play in the Photosynthesis process?

• They decompose organic matter in soil.

• Some bacteria, like cyanobacteria, can perform photosynthesis, contributing to the production of oxygen and organic matter in aquatic ecosystems.

• They inhibit the growth of plants by consuming nutrients.

• Bacteria have no role in the photosynthesis process.

What is the function of Thylakoids in chloroplasts?

• Thylakoids are involved in the synthesis of glucose during photosynthesis.

• Thylakoids are membrane-bound structures that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

• Thylakoids store energy in the form of ATP for the plant.

• Thylakoids are responsible for the absorption of water in the chloroplasts.

What are Phytoplankton?

• Microscopic animals that live in aquatic environments

• Microscopic plants that live in aquatic environments and perform photosynthesis

• Large marine mammals that feed on fish

• Bacteria that decompose organic matter in water

How do plants obtain Carbon Dioxide for Photosynthesis?

• Through small openings in their leaves called stomata.

• By absorbing it through their roots from the soil.

• From water during the process of transpiration.

• By converting sunlight into energy and releasing oxygen.

What is the primary source of energy for Photosynthesis?

• Sunlight

• Water

• Carbon Dioxide

• Soil Nutrients

What is Stroma in the context of chloroplasts?

• The outer membrane of the chloroplast

• The fluid-filled space inside chloroplasts that surrounds the thylakoids and contains enzymes, chloroplast DNA, and starch.

• The site of photosynthesis within the chloroplast

• The pigment that captures light energy in chloroplasts.
