AP BIOLOGY

Detailed explanation-1: -Phloem transport food and nutrients such as sugar and amino acids from leaves to storage organs and growing parts of the plant. Xylem transport water and minerals from roots to aerial parts of the plant.

Detailed explanation-2: -Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients.

Detailed explanation-3: -Phloem are tissues that look like tubes. They transport sugars throughout the plant and supply it to tissues like roots, flowers and fruits that depend on this sugar to grow. Think of them like the veins in our body that move blood. Moving sugars from cells in the leaves to cells in the phloem is difficult for plants.

Detailed explanation-4: -Phloem parenchyma cells, called transfer cells and border parenchyma cells, are located near the finest branches and terminations of sieve tubes in leaf veinlets, where they also function in the transport of foods.

Detailed explanation-5: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
