Photosynthesis Concepts and Processes

The video explains how plants grow by making their own food through photosynthesis. It details the essential elements needed for this process: sunlight, carbon dioxide, and water. The role of chlorophyll in converting sunlight into chemical energy is highlighted, leading to the production of oxygen and simple sugars. These sugars are distributed to provide the necessary nutrients for plant growth.

How do plants differ from animals in terms of obtaining food?

• Plants eat other organisms.

• Plants produce their own food.

• Plants absorb nutrients from the soil.

• Plants do not need food.

What are the basic elements required for photosynthesis?

• Oxygen, nitrogen, and sunlight

• Carbon dioxide, water, and sunlight

• Water, soil, and oxygen

• Nitrogen, carbon dioxide, and water

What role does sunlight play in photosynthesis?

• It helps in absorbing nutrients from the soil.

• It directly converts water into oxygen.

• It provides energy to combine carbon dioxide and water.

• It cools down the plant during the process.

What is the function of chlorophyll in the leaves?

• It stores food for the plant.

• It releases oxygen into the air.

• It converts sunlight into chemical energy.

• It absorbs water from the soil.

What happens to the oxygen produced during photosynthesis?

• It is converted into carbon dioxide.

• It is stored in the roots.

• It is released into the air.

• It is used by the plant for growth.
