_____ tissue transports food to plants

🔑Key Points:
Phloem tissue transports food to plants.
In plants, the synthesized food molecules by the leaves are transported to the different storage organs- roots, stem, fruits with the help of vascular tissue called phloem.
Phloem is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed.
This transport process is called translocation.
The phloem carries food downward from the leaves to the roots.
Xylem cells constitute the major part of a mature woody stem or root.
Hence, the correct option is 3.

🔴Additional Information:

• Xylem :
Xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
Xylem can be found in vascular bundles, present in non-woody plants and non-woody parts of woody plants. 

• Parenchyma :
The functional tissue of an organ as distinguished from the connective and supporting tissue.
Parenchyma tissue is composed of thin-walled cells and makes up the photosynthetic tissue in leaves, the pulp of fruits, and the endosperm of many seeds.

• Collenchyma :
Collenchyma, in plants, supports the tissue of living elongated cells with irregular cell walls.
Collenchyma cells have thick deposits of cellulose in their cell walls and appear polygonal in cross-section.
The strength of the tissue results from these thickened cell walls and the longitudinal interlocking of the cells.
