Plants prepare glucose in the process of :

Plants prepare glucose through the process of photosynthesis. During this process, plants utilize carbon dioxide and water in the presence of sunlight and chlorophyll to synthesize glucose and oxygen [2]. Leaves act as the primary 'food factories' where this synthesis occurs [3]. The glucose produced serves as an immediate energy source or is converted into starch for long-term storage [2]. In contrast, respiration is the process where plants break down glucose to release energy, consuming oxygen and releasing carbon dioxide [1]. While mineral absorption involves the intake of nutrients via the xylem, it does not synthesize glucose [1]. Photosynthesis is a synthesis reaction that allows autotrophic organisms like plants to manufacture their own food (organic molecules) from inorganic raw materials.
