A mature vascular plant any plant other than mosses and liverworts , contains several types of differentiated cells. These are grouped together in tissues.


Parenchyma is the precursor of all the other tissues. The collenchyma cell is usually having a compact cell arrangement with little or no intercellular space. Identification of Parenchyma, Collenchyma and Sclerenchyma tissues in plants, striped, smooth and cardiac muscle fibres and nerve cells in animals from prepared slides. Plant tissues can be categorised based on their structure and functions performed. Plant tissues can also be divided differently into 2 types: Plant Tissues - Ground Tissue Some major types of plant cells: Parenchyma Collenchyma Sclerenchyma Tissues that are neither dermal nor vascular are ground tissue. Parenchyma cells of xylem are mainly involved in the storage of carbohydrate, fats and water conduction.

Like animals, plants are multicellular eukaryotes whose bodies are composed of organs, tissues, and cells with highly specialized functions. The relationships between plant organs, tissues, and cell types are illustrated below. The stems and leaves together make up the shoot system. Each organ roots, stems, and leaves include all three tissue types ground, vascular, and dermal. Different cell types comprise each tissue type, and the structure of each cell type influences the function of the tissue it comprises. We will go through each of the organs, tissues, and cell types in greater detail below.


Vascular tissue is a complex conducting tissue , formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.

All the tissues of a plant which perform the same general function, regardless of position or continuity in the body, constitute the tissue system. The tissues of a plant are organized to form three types of tissue systems: the dermal tissue system, the ground tissue system, and the vascular tissue system. The cells of epidermis are parenchymatous having protoplasm and nucleus without intercellular spaces. Epidermis possesses numerous minute openings called stomata. Main function of stomata is exchange of gases between the internal tissues and the external atmosphere. Cuticle is present on the outer wall of epidermis to check evaporation of water. Epidermis forms a Protective layer in leaves, young roots, stem, flower, fruits etc.
