The part that synthesizes food is the chloroplast, the double-membrane organelle containing chlorophyll that carries out photosynthesis, converting light energy, carbon dioxide, and water into glucose and oxygen through biochemical reactions in the thylakoids and stroma.

The part that produces energy is the mitochondrion, often called the powerhouse of the cell, which generates ATP through cellular respiration by breaking down glucose and other organic molecules through the Krebs cycle and electron transport chain in its inner membrane cristae.

The vacuole serves as the storehouse of organic substances like proteins, organic acids, and various metabolic wastes; in plant cells, the large central vacuole can occupy up to 90% of cell volume, also maintaining turgor pressure and storing pigments, ions, and toxic waste products.

The Golgi apparatus packages materials coming from the endoplasmic reticulum, modifying, sorting, and packaging proteins and lipids into membrane-bound vesicles for secretion outside the cell or delivery to specific cellular destinations like lysosomes or the plasma membrane.

The nucleus determines function and development of the cell by housing the cell's genetic material (DNA) organized into chromosomes, controlling gene expression, directing protein synthesis through RNA production, and regulating cell division, growth, and metabolic activities through its role as the command center.
