Which tissue is protective tissue?
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).
Which tissue provides support and protection to plants?
Collenchyma cell is the simple permanent tissue which generally has a thin wall with irregular thickening at the corners. The cell wall is composed of lignin and pectin. They provide structural support, particularly in growing shoots and leaves.
What are supporting tissues?
Supporting tissues are types of connective tissues. It forms the framework and supporting structures of the body, including bone, cartilage, mucous membrane, and fat. Parenchyma, Collenchyma, Sclerenchyma, Vascular tissues (Xylem, Phloem) are the supporting tissues in plants .
Why are epidermal and cork cells called protective tissues?
epidermis and cork cells are known as protected tissue because epidermis and cork cells protect the plant from water loss and protects the plant from insects. epidermis and cork cells had waxy coating known as cutin and suberin which helps the plant from water loss .
Why Epithelial tissue is called protective tissue?
Explanation: Epithelial tissue covers and protects many organs and cavities within the body. … In skin, many layers of epithelial cells are present to prevent wear and tear. Hence, it acts as a protective tissue in the animal body.
Which tissue provides structural support and protection against breakage?
Collenchyma is found near the surface of cortex in stems and along the veins of leaves, where it provides structural support and protection against breakage.
WHO provides support to the plants?
Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
Which of the following provides primary support and protection for body structures?
A type of connective tissue that provides primary support and protection for body structures is: osseous tissue.
Is xylem a supporting tissue?
Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential ‘supporting’ role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.
What are conducting tissues?
noun. tissue of higher plants consisting mainly of xylem and phloem and occurring as a continuous system throughout the plant: it conducts water, mineral salts, and synthesized food substances and provides mechanical support. Also called: conducting tissue.
What are the three types of supporting tissue?
Vascular plants have up to three types of supporting tissue: The collenchyma, a tissue of living cells, the sclerenchyma, a tissue of nearly always dead cells, and. the vascular tissue consisting of both living and dead cells.
What is protective tissue 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 is epidermis and cork?
Epidermal cells and cork cells are two types of cells in the outermost layer of the cells. Epidermal cells are arranged in a single layer to cover the whole plant body during primary growth. Cork cells are produced by the cork cambium during secondary growth of plants.
What is the function of epidermis and cork and stomata?
The epidermis serves several functions: it protects against water loss, regulate gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. B. Cork : The walls of cork cells contain a chemical called suberin, which makes them impermeable to water and gases.
