Photosynthesis Review

What is the primary function of the xylem in plants?

• To transport water and minerals from the roots to the leaves.

• To store food and nutrients for the plant.

• To conduct photosynthesis and produce energy.

• To provide structural support and strength to the plant.

What are the reactants in the chemical equation for photosynthesis?

• H₂O + CO₂

• O₂ + C₆H₁₂O₆

• H₂ + O₂

• CO + H₂O

What is the light-independent reaction (Calvin Cycle) in photosynthesis?

• It is the phase where ATP and NADPH are used to convert CO₂ into glucose.

• It is the phase where light energy is captured and converted into chemical energy.

• It is the phase where glucose is broken down to release energy.

• It is the phase where oxygen is produced as a byproduct of photosynthesis.

What is one of the most important compounds for storing and releasing energy in organisms?

• ADP

• ATP

• NADH

• FADH2

What are stomata and their function in photosynthesis?

• Stomata are small openings on the leaf surface that allow gas exchange.

• Stomata are large pores that absorb water from the soil.

• Stomata are structures that store chlorophyll for photosynthesis.

• Stomata are cells that produce energy through cellular respiration.

What is the significance of glucose produced in photosynthesis?

• It is a waste product of photosynthesis.

• It serves as an energy source and a building block for growth.

• It is used to produce oxygen during photosynthesis.

• It helps in the absorption of sunlight.

What is the overall equation for photosynthesis?

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

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

• C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

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

What tissue carries sugars and nutrients away from the leaf to other parts of the plant?

• Xylem

• Phloem

• Cortex

• Epidermis

What role does chlorophyll play in photosynthesis?

• Chlorophyll absorbs light energy, primarily from the sun.

• Chlorophyll releases oxygen as a byproduct of photosynthesis.

• Chlorophyll helps in the absorption of water from the soil.

• Chlorophyll converts carbon dioxide into glucose.

What is the importance of water in photosynthesis?

• Water is a reactant in photosynthesis and is essential for the production of glucose and oxygen.

• Water is a byproduct of photosynthesis and has no significant role.

• Water helps in the absorption of sunlight during photosynthesis.

• Water is used to cool the plant during photosynthesis.
