In permanent tissue cells have lost the capacity of cell division.

Plant tissue differentiate into three main types: dermal, vascular, and ground tissue. Dermal tissue covers and protects the plant. Vascular tissue transports water, minerals, and sugars to different parts of the plant.

Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope.

Xylem is associated with translocation of mainly water, mineral salts, some organic nitrogen and hormones, from roots to the aerial parts of the plants. The phloem translocates a variety of organic and inorganic solutes, mainly from the leaves to other parts of the plants.

Smooth muscle (so-named because the cells do not have striations) is present in the walls of hollow organs like the urinary bladder, uterus, stomach, intestines, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive system.

Camels humps are made from fatty adipose tissue. This concentrated fat minimizes heat trapping throughout the rest of the body. When the fat tissue is metabolized, it becomes energy and also yields more than 1gram of water.

Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.

The transport of organic substances in plants is through phloem.

On the basis of that 1902 address and his pioneering experimentation before and later, Haberlandt is justifiably recognized as the father of plant tissue culture.
