In photosynthesis, the plant uses water and nutrients from the soil, and carbon dioxide from the air with the sunâs energy to create photosynthates. Oxygen is releases as a byproduct. Figure 2.thletes take up oxygen through their lungs. Plants take up oxygen through the stomata in their leaves and through their roots. Again, respiration is the burning of photosynthates for energy to grow and to do the internal âworkâ of living.
