Hint: Protective tissues are generally present in the outermost layer of the plant body such as leaves, stem, and roots, and offer safety to the plant body. They stop desiccation, mechanical injury, and infection in plants. Complete answer: The protective tissues in plants consist of epidermis and cork (phellem).
What is the example of protective tissue?
Protective tissue covers the surface of leaves and the living cells of roots and stems. Its cells are flattened with their top and bottom surfaces parallel. The upper and lower epidermis of the leaf are examples of protective tissue [View].
What are protective tissues Class 9?
Protective tissues are usually present in the outermost layer of the plant body such as leaves, stem and roots and offer protection to the plant body. They prevent desiccation, mechanical injury, and infection in plants.
What are the protective tissues in plants explain them in detail with suitable examples?
The protective tissues in plants include epidermis and cork (phellem). Epidermis It is the outermost covering of cells in plants. It performs protective function (protecting plants from some adverse conditions). It is usually made up of single layer of cells.
What is known as protective tissue?
Epidermis is the first layer of the body of both plants and animals that acts as the first line of defense against various types of harmful objects. It protects the other parts of the body from injuries, bacterial attacks etc. For this reason, epidermis is known as protective tissue.
How many protective tissues are there?
4 Protective Tissues. Protective tissues are divided into two parts: Epidermis. Cork/Phellem.
Why are they called protective tissue?
Epidermal and cork tissues are present on the outermost surface of the tree, and take any impact inflicted upon the tree. They also provide rigidity to the plant and cover the vascular tissues of the plant, protecting them from physical blows. So they are called the protective tissues of the plant.
Why epidermis is called protective tissue class 9?
Explanation: The epidermis is considered a protective tissue because its prime purpose is to form a physical barrier between the outside and inside of the body. On the top stratum (layer) of the epidermis, the cells are dead, and so have no physiological function besides to form a barricade against the outside.
Which is the protective tissue in animal body?
The covering or protective tissues in the animal body are epithelial tissues. Epithelium covers most organs and cavities within the body. It also forms a barrier to keep different body systems separate.
What are three types of protective tissues?
- Protective Tissue : It includes epidermis and cork.
- Epidermis : It is usually present in the outermost layer of the plant body such as leaves, flowers, stem and roots. …
- Cork : As roots and stem grow older with time (increase in girth), tissues at the periphery become cork cell.
Which are the external protective tissues of plant?
The dermal tissue system—the epidermis—is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds). The epidermis is usually one cell layer thick, and its cells lack chloroplasts.
What is the main function of protective tissue in plants?
The protective tissue is those tissue, which is present in the outermost layer of the plant such as roots, stem, and leaves. Protective tissue prevents desiccation, mechanical injury, and infection in plants. They form a protective barrier which does not allow the entry of the pathogen into the plant.
Which tissues are called covering or protective tissue?
Epithelial tissues are called covering or protective tissues.
What are the function of protective tissue?
Answer:Answer: The protective tissue is those tissue, which is present in the outermost layer of the plant such as roots, stem, and leaves. Protective tissue prevents desiccation, mechanical injury, and infection in plants. They form a protective barrier which does not allow the entry of the pathogen into the plant.
