Leaf, cell, chloroplast, glucose molecule, water molecule.
Explanation:
Various structures and elements are involved in photosynthesis. The leaf with its unique cell structure produces carbon dioxide and energy from water and oxygen utilizing sunlight. The leaf has special structures called mesophyll cells which contain chloroplasts. The chloroplasts contain the thylakoid membrane that contain the green pigment chloroplasts which involve in photosynthesis. Glucose molecule is the product of photosynthesis while water molecule is the reactant; where a single glucose molecule produced requires six water molecules to be oxidized.
