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: -Vascular tissues are those tissue that is responsible for the transport of food, minerals, and water throughout the plant. Plants have two primary vascular tissues, the xylem, and the phloem.

Detailed explanation-3: -Plant Physiology and Development Phloem is one of the two tissues that make up the plant’s long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored.

Detailed explanation-4: -Food and other organic substances (e.g., some plant hormones and even messenger RNAs) manufactured in the cells of the plant are transported in the phloem. Sugars (usually sucrose), amino acids and other organic molecules enter the sieve elements through plasmodesmata connecting them to adjacent companion cells.
