EVERYDAY SCIENCE

Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -Most plants are autotrophs because they make their own food by photosynthesis. But for every rule there is an exception. Some plants are non-photosynthetic and parasitic, obtaining their food through a host.

Detailed explanation-3: -The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis (Figure 1). While carbon dioxide is absorbed by the leaves, the sunlight is captured by a chemical molecule in the plant, called chlorophyll (Chl). All photosynthetic organisms contain Chl.
