The Function and Cell Types of Epithelial Tissue.
The ground tissue system is important because it serves a variety of essential functions for plants. Ground tissue is made up of three types including parenchyma, collenchyma, and sclerenchyma.
In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
The major cells of the ground tissue are parenchyma cells, which function in photosynthesis and nutrient storage. They have thin walls, many chloroplasts, and large central vacuoles, and they form the mass of most leaves, stems, and roots. Another cell of the ground substance is the sclerenchyma cell.
The material between the cells of connective tissue consists of fibers and an amorphous gel-like component called the ground substance. The potential importance of the ground substance is readily apparent; for it is through this material that nutrients supplied by the blood diffuse. The ground substance contains glycoproteins and proteoglycans.

It is composed of large, thick-walled cells which develop to for ground tissue system, i.e. hypodermis, cortex and pith. IV. Classification on basis of plane of divisions: The growth pattern and plane of division of meristematic tissue is important to govern the mode of growth. These tissues can be divided into three types: (i) Mass meristem.
Meristematic plant tissue is different than all other plant tissue, in that it is the main growth tissue of the plant. All cells originate from one meristem or another. The apical meristem is the plant tissue which drives above ground growth, and decides the direction of the plant. Root meristems dig into the soil in search of water and nutrients.
Ground Tissue. Ground tissue is mostly made up of parenchyma cells, but may also contain collenchyma and sclerenchyma cells that help support the stem. The ground tissue towards the interior of the vascular tissue in a stem or root is known as pith, while the layer of tissue between the vascular tissue and the epidermis is known as the cortex.
A tissue is a group of cells, in close proximity, organized to perform one or more specific functions. There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Tissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material. By definition, tissues are absent from unicellular organisms. Learn more about tissues in this article.
Plant Cells, Tissues, and Tissue Systems. Plants, like animals, have a division of labor between their different cells, tissues, and tissue systems. In this section we will examine the three different tissue systems (dermal, ground, and vascular) and see how they function in the physiology of a plant.
A collection of cells performing a specific function is called tissue. Plant tissues can be grouped into plant tissue systems each performing specialized functions. A plant tissue system is defined as a functional unit, connecting all organs of a plant. Plant tissue system is also grouped into various tissues based on their functions.
Trabecular bone gives supporting strength to the ends of weight-bearing bones and contains many tiny spaces that are filled with marrow. Cortical bone on the outside forms the shaft of the long bone. Each bone contains two types of osseous tissue. Compact bone is dense and solid and is always found on the surface of the bone. Spongy bone has.
