How do root cells get energy though they do not do photosynthesis

Answer 1

Root cells do not directly produce their own energy through photosynthesis like leaf cells do. Instead, they rely on the sugars and nutrients produced through photosynthesis in the leaves and transported through the plant's vascular system. These sugars and nutrients are transported to the roots where they are used as a source of energy for cellular processes such as growth, maintenance, and nutrient uptake.

Additionally, root cells can also obtain energy through the process of respiration. During respiration, cells break down sugars and other organic molecules to release stored energy in the form of ATP (adenosine triphosphate). This energy is used by the root cells to carry out essential functions within the plant.

Overall, although root cells do not perform photosynthesis, they are still able to obtain energy from sources such as sugars produced in the leaves and through cellular respiration.
