Stomata are not composed of a single layer of epidermis cells; rather, they are openings that penetrate the epidermis and allow gas exchange.

The process by which cells differentiate into specialized cells is called differentiation.

Meristematic tissue is composed of cells that are undifferentiated or incompletely differentiated and continue to divide, contributing to the growth of the plant.

The main function of collenchyma is to provide mechanical support to young stems and leaves via turgor.

Meristematic tissue cells are undifferentiated or incompletely differentiated and continue to divide and contribute to the growth of the plant. Meristematic tissue cells can differentiate into different types of meristematic tissue, but not into dermal, vascular, and ground tissue. These tissue types are formed from the cells that quickly differentiate from the meristematic tissue.

Totipotent stem cells can differentiate into any cell type, including embryonic and extraembryonic cells.

The epidermis is an example of dermal tissue. It is composed of a single layer of epidermis cells and may contain stomata and guard cells that allow gas exchange, root hairs that increase surface area, or trichomes used in transpiration or defense. It may also contain a waxy cuticle if found on the upper surface of leaves to aid in lowering transpiration.

Collenchyma is the type of ground tissue that has elongated cells with an unevenly thickened primary cell wall. Its main function is the mechanical support of young stems and leaves via turgor.

Sclerenchyma cells provide support and structure to plant tissues.

Primary meristem rises at the early stage of a plant and comprises of apical and intercalary meristem. Secondary meristem rises at the later stage of a plant and comprises of lateral meristem. Apical meristem is present at tips of root and shoot and also helps in the increase of length. Intercalary meristem is found at the base of the internodes in certain plants and is responsible for the growth in length between the nodes, but it does not contribute to the increase in girth or diameter of the stem.
