FAQs on Worksheet Solutions: Stepwise Thinking

1. What are the key components of a plant cell?
Ans. The key components of a plant cell include the cell wall, which provides structure; the chloroplasts, which are essential for photosynthesis; the vacuole, which stores nutrients and waste products; and the nucleus, which contains the cell's genetic material.
2. How does photosynthesis benefit the environment?
Ans. Photosynthesis benefits the environment by producing oxygen, which is essential for the survival of most living organisms, and by absorbing carbon dioxide, a greenhouse gas, thus helping to mitigate climate change.
3. What role do chloroplasts play in photosynthesis?
Ans. Chloroplasts are the organelles in plant cells where photosynthesis occurs. They contain chlorophyll, which captures sunlight and converts it into chemical energy, facilitating the transformation of carbon dioxide and water into glucose and oxygen.
4. What is the equation for photosynthesis?
Ans. The equation for photosynthesis can be summarised as: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂, where carbon dioxide and water, in the presence of light, are converted into glucose and oxygen.
5. Why is sunlight essential for photosynthesis?
Ans. Sunlight is essential for photosynthesis because it provides the energy required to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen, thus supporting the growth and energy needs of the plant.
