Roots absorb water and mineral nutrients from the soil., Xylem transports water and dissolved minerals from the roots to the leaves., Leaves take in carbon dioxide through tiny openings called stomata and capture sunlight using chlorophyll., Photosynthesis occurs in the chloroplasts, using water, carbon dioxide, and light energy to produce glucose and oxygen., Glucose is transported or used by different plant cells as a source of energy and as a material for growth and storage through the phloem., Cellular respiration breaks down glucose to release energy, usually using oxygen., Mitochondria are major sites of cellular respiration, where much of the energy released is captured in ATP., ATP supplies usable energy for plant activities such as growth, active transport, cell division, and the synthesis of substances.
