name the different types of plant tissue and write the structure and funsion of those tissue
Answers
Answer:
Plant tissue is a collection of similar cells performing an organized function for the plant. Each plant tissue is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems and roots. The following is a brief outline of plant tissues, and their functions within the plant.
Types of Tissue in Plants
Meristematic Tissue
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. Subapical meristems divide the plant and carry leaves in different directions. Intercalary meristems provide growth from the middle of the plant, to extend the leaves upward into the sunlight.
Simple plant tissue
There are several basic forms of plant tissue, formed from mostly identical types of cells. The first is the epidermis. The epidermis in plants serves the same function as it does in animals. It is a plant tissue formed of thin and densely packed cells, meant to separate the inside of the organisms from the outside. The epidermis is often covered in a layer of waxy protection, to stop the plant from burning or drying out in the sun. The epidermis also contains guard cells, which operate small opening called stoma. These stoma control the passage of air and water through the leaves, allowing plants to move water and nutrients up from the soil.
Complex Plant Tissue
The complex tissues in a plant deal with moving nutrients and water to the leaves, while removing the products of photosynthesis from the leaves. Photosynthesis produces the sugar glucose. Modified and bound to other 6-carbon sugars, the substance becomes sucrose or a variety of other disaccharides. In this form it can be moved with small amounts of water and can be transported efficiently throughout the plant. The complex tissues of the plant aid in this overall effort to supply the roots with food as they supply the leaves with water and nutrients.
Explanation:
• parenchyma _ these tissues are found in the soft parts of a plant such as roots ,stems , leaves , and flowers .
• Sclerenchyma _ the cells of this tissue are dead
