Tracheids and vessels in xylem are responsible for conducting water and minerals vertically throughout the plant. Their tubular structure and thick walls facilitate efficient transport.

The main components of xylem are tracheids, vessels, xylem parenchyma, and xylem fibers. Phloem is composed of sieve cells, sieve tubes, companion cells, phloem fibers, and phloem parenchyma.

Vascular tissues such as xylem and phloem enable the efficient transport of water, minerals, and nutrients throughout the plant. This transport system is essential for the distribution of resources required for growth, metabolism, and reproduction, thus facilitating the survival of ...

Xylem is responsible for conducting water and minerals from the roots to the rest of the plant, while phloem transports organic nutrients like sugars produced during photosynthesis from the leaves to other parts of the plant.

Simple permanent tissues are made of one type of cells that look similar to each other, while complex tissues are made of more than one type of cells that coordinate to perform a common function.

The primary function of cork cells is to provide a protective barrier for the underlying tissues, as they are dead and compactly arranged, impervious to gases and water due to the presence of suberin in their walls.

The outer layer of a branch, formed by secondary meristem in the cortex, undergoes changes to produce cork, while the outer layer of a young stem does not yet have this specialized tissue.
