Final answer:
In plant cells, food can be stored as starch, alongside other forms such as fat or other polysaccharides, with starch being the primary storage form of glucose in plants.
Step-by-step explanation:
In plant cells, food is stored in the form of starch, fat, or other polysaccharides. Starch serves as the main storage form of glucose in plants and consists of two molecules, amylose and amylopectin. These compounds are both polymers of glucose.
Plants synthesize glucose through photosynthesis and store excess glucose as starch in parts like roots and seeds, which can then be used for energy later on. In humans and animals, starch is broken down into smaller molecules, such as maltose and glucose, which our cells can absorb.
