Cells of meristematic tissue are totipotent as they are composed of immature and undifferentiated cells, which are either in a continuous state of division or retain the power of division.

Lignification is the process which makes the plant tissues woody.

Collenchyma forms long, flexible but strong strands in leaf stalks.and provides support fills vacant spaces that will be used for later growth.

Flesh of a fruit is mostly made up of parenchyma.They possess dense cytoplasm and are active metabolites.

Sclerenchyma has dead cells. They are thick walled and are usually lignified.

Stratified epithelium is present in the epidermis of skin of vertebrates.

Transitional epithelium is found in ureter. It is a stratified epithelium in which the shape of the surface cells changes (undergoes transitions) depending on the degree of stretch.

Fibrocytes secretes the matrix of the connective tissue. A fibrocyte is an inactive mesenchymal cell, that is, a cell showing minimal cytoplasm, limited amounts of rough endoplasmic reticulum and lacks biochemical evidence of protein synthesis

Modified white fibrous tissues are present in tendons.

Stratified squamous epithelium is present in cornea, oesophagus, urethra and vagina.
