Final answer:
Plants generate their food by photosynthesis, utilizing sunlight, water, and CO₂, with excess sugars often stored in plant parts such as stems.
Step-by-step explanation:
Plants do not consume food like animals; they make their sugars through a process called photosynthesis.
The food is produced in every leaf of the plants. Leaves use carbon dioxide, water, and energy from the sun to produce food. The roots absorb water from the soil and the stomata allow carbon dioxide to enter the leaf through tiny pores. The excess amount of food produced by the plant is stored in different parts; for example, in the sugar cane plant, it is stored in the stems.
