NEET BIOLOGY

Detailed explanation-1: -Plants use two different transport systems, both of which are rows of cells which form tubes around the plant.. The xylem transports water and minerals from the roots to the leaves while the phloem moves food substances from leaves to the rest of the plant.

Detailed explanation-2: -When the plant opens its stomata to let in carbon dioxide, water on the surface of the cells of the spongy mesophyll and palisade mesophyll evaporates and diffuses out of the leaf. This process is called transpiration . Water is drawn from the cells in the xylem to replace that which has been lost from the leaves.

Detailed explanation-3: -Translocation is the movement of elements within a plant from leaves to other tissue. Plants’ phloem, a type of vascular tissue, is where translocation takes place. Sugars that are produced by photosynthesis or that are stored in plant tissues like roots, bulbs, and tubers are examples of sugar sources.

Detailed explanation-4: -Translocation occurs within a series of cells known as the phloem transport system, which is the most important digestive tissue of plants. Nutrients move to phloem as solutes in a solution called phloem liquid.
