On the work of which plant organs does the life of the leaves depend?

Any plant is a system, and any system cannot work without one part. Therefore, the life of the leaves and the plant as a whole depends on the root and other parts of the shoot. Also, the leaves are important for plant life, as they produce glucose, which serves the plant as a source of energy. Water and minerals enter the cells of the leaves through the root and the conductive vessels in the stems. Also, in the stems there are sieve tubes that carry organic matter throughout the plant’s body to ensure life.
