Simple tissue

Geography Simple Epithelial Tissues The surface of our body and internal organs is subjected to wear, tear and injury.

Simple tissue

Hence, simple tissue is homogeneous and complex tissue is heterogeneous. Simple Tissue Simple tissue is made up of same type of cells and mostly cover the surface of both, internal organs of the body and external organs of the body.

Simple tissue is tightly packed together. A simple tissue is called epithelium in animals and epidermis in plants. Example of simple tissue is muscle tissue. Complex Tissue Complex tissue is made up of different type of cells.

The main purpose of complex tissue is to actually bind organs together and to support them. These tissues are scattered everywhere in the body. They are also known as connectivity tissue in animals and vascular tissue in plants.

Example of complex tissue is blood tissue. Key Differences Simple tissue consist of one same type of cells while complex tissue have different type of cells.

3 Types of simple tissues :Parenchyma, Collenchyma and Sclerenchyma Parenchyma, Collenchyma and Sclerenchyma Article shared by Simple tissues are a collection of similar cells that perform a common function. These tissues are of 3 types.

Simple tissue occur in all parts of plant and complex tissue only occur in vascular region. Simple tissue have wide distribution and complex tissue have restricted distribution. Complex tissue carries out function of conduction or transportation.

Simple tissue

Simple tissues perform wide range of functions. The function of simple tissue is storage of food, while the function of complex tissue is protection. Complex tissue prevent water loss and they even help in gaseous exchange.In Simple Epithelial Tissues, the cells of the tissue are arranged in a single layer.

The cells are rests on a non-cellular basement membrane which is composed of a network of collagen fibres. Types of Simple Epithelium. Parenchyma (Figs. , ) is a cell and tissue type in which the cells have only thin primary walls; the cells are unspecialized, lack the characteristic wall of collenchyma and the secondary walls of sclerenchyma; the cells have live nucleate protoplast concerned with various physiological activities in plants; the cells are meristematic, or permanent, .

The main difference between simple and complex tissue is, simple tissues are made up of cells of same type or kind and complex tissues are made up of different.

Hence, simple tissue is homogeneous and complex tissue is heterogeneous. They are living. This tissue is present in all organs of the plant e.g., roots, stems, leaves, flowers, fruits and seeds. Functions ; The main function of this tissue is storage of food. 2. In fleshy stems and Fig.

Parenchyma. leaves parenchyma cells function as water storage tissue e.g., Opuntia, ^Euphorbia, 3.

Simple Columnar Epithelium

Sclerenchyma is another simple tissue nicely adapted for mechanical function. The component cells are usually ‘prosenchymatous’, a term once used to designate the cells much longer than breadth.

The walls are considerably thickened, often heavily lignified with simple pits. Other articles where Simple tissue is discussed: angiosperm: Vegetative structures: performing only one function are simple tissues, while those composed of more than one cell type and performing more than one function, such as support and conduction, are complex tissues.

Xylem and phloem are examples of complex tissues.
