Final answer:
The true statement is that sugar molecules form starches, with starch being the storage form of glucose in plants, compounded as amylose and amylopectin.
Step-by-step explanation:
Of the given statements, the one that is true is that sugar molecules form starches. In plants, glucose is synthesized through photosynthesis, and the excess glucose is stored as starch in various plant parts such as roots and seeds. Starch is a polysaccharide made up of a mixture of two glucose polymers, amylose (linear) and amylopectin (branched).
When required, starch can be broken down back into glucose molecules to be used for energy.This dynamic interconversion between sugar molecules and starch exemplifies the intricate metabolic processes within plants, showcasing how the storage and retrieval of glucose in the form of starch play a pivotal role in providing energy as needed for the plant's growth, development, and reproductive processes.
