Extracellular Matrix. Epidermis - upper layer; epithelial tissue that can further be subdivided into sublayers. The function of key structural features are listed in the table below. The tissues […] This tissue, also known as the plant epidermis, forms the outermost layer of cells and is usually only one cell layer thick. I. Keratinocytes: produce keratin, a fibrous protein that helps the epidermis protect. The four big groups are epithelial tissue, connective tissue, muscle tissue and nervous tissue. This layer represents the point of contact between the plants and the outer environment and, as such exhibits diversities in structure. Epidermis: keratinized stratified squamous epithelium of 4 different cell types and 4-5 distinct cell layers. Keratinocytes are responsible for producing keratin, a protective protein that makes up skin, nails, and hair. It contains collagen fibres and fibroblasts. * The thickness of a cuticle in plants is largely dependent on the type of plant and where they are located. Dermis: Dermis contains an extracellular matrix. Beneath the Squamous cells, there are round shaped cells present which are called Basal cells. When cells of the same type work together to perform a collective function, the collection of cells is called a tissue.For example, the epidermis is a collection of parenchyma-like cells working together to separate the internal environment of the plant from the exterior. Epithelium a type of tissue (the others being Muscle, Connective and Nervous) that lines internal and external surfaces.
