Which statement best describes plants?

Plants are classified as many-celled organisms that have the unique ability to produce their own food through the process of photosynthesis. This process involves utilizing sunlight to convert carbon dioxide and water into glucose and oxygen. The presence of chlorophyll, a green pigment found in plant cells, is crucial for capturing light energy from the sun. This characteristic is one of the defining features of plants, setting them apart from other forms of life.

In contrast, the other options do not accurately describe plants. For instance, organisms without cell walls or those that consume other organisms are categorized differently—such as animals or bacteria. Additionally, single-celled organisms lacking chlorophyll would typically fall into categories like some types of protists or certain bacteria, rather than being recognized as plants.
