FAQs on Worksheet: How Do Plants Make Their Food - 2

1. How do plants make their food?
Ans. Plants make their food through a process called photosynthesis. They use sunlight, carbon dioxide, and water to produce glucose (a type of sugar) and oxygen. This process takes place in the chloroplasts, which contain a pigment called chlorophyll.
2. What is photosynthesis?
Ans. Photosynthesis is the process by which plants convert sunlight into energy. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts, which are specialized structures found in plant cells.
3. What are the essential components for photosynthesis?
Ans. The essential components for photosynthesis are sunlight, carbon dioxide, and water. Sunlight provides the energy needed for the process, while carbon dioxide and water serve as the raw materials. In the presence of chlorophyll, these components are used by plants to produce glucose and release oxygen.
4. Why is chlorophyll important in photosynthesis?
Ans. Chlorophyll is important in photosynthesis because it is the pigment that absorbs sunlight. It captures the energy from sunlight and converts it into chemical energy, which is used to power the process of photosynthesis. Chlorophyll gives plants their green color and is essential for their ability to produce food.
5. What is the role of glucose in plants?
Ans. Glucose plays a crucial role in plants as it serves as their main source of energy. It is used for various metabolic processes, such as growth, reproduction, and repair. Additionally, glucose can be stored in the form of starch for future use. Some glucose may also be converted into other organic compounds needed by the plant.
