In the woody plants the epidermis of the stem is replaced by periderm whose major component is the cork. Reason why epidermis and cork are called protective tissue: a) Since the entire surface of a plant has outer covering of epidermis. It protects all the parts of the plant.
Why are epidermal cells and cork cells called the protective tissue?
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 epidermis is called protective tissue?
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.
What is the protective role of cork and epidermis?
It carries out protective function (protecting plants from some unfavorable conditions). It is generally made up of a single layer of cells. In arid habitats, the epidermis is thicker to protect the plant from undue loss of water. … Cork cells avert desiccation, infection, and mechanical injury.
What is the function of cork and epidermal cells?
During primary growth, epidermis cells form a single layer that covers the entire plant body. Cork cells are produced by the cork cambium during the secondary growth of plants. Water-repellent substances are found in both epidermis and cork cells, which help to prevent water loss from the plant body.
What is cork and epidermis explain?
Answer Expert Verified
An epidermis is a single-layered group of cells which are used for covering the plant leaves, roots, stem, and flowers. … The cork, on the other hand, is a waterproof protective layer which can be found on the cork trees and consists of dead cells and this is impermeable in nature.
What is the difference between epidermal cell and cork cell?
The main difference between epidermal cells and cork cells is that epidermal cells cover the entire plant body during primary growth whereas cork cells cover the stem and root of the plant after the secondary growth of the plant. … They occur as a single layer of cells.
What is meant by protective tissue?
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.
How is cork formed mention its role?
Cork is formed by the division of cork cambium or the lateral meristem(phelloderm). Cork provides mechanical strength to trees and is fire resistant.
What is the special character of cork tissue?
Answer: The characteristics of cork are as follows: Cells of cork are dead at maturity. These cells are compactly arranged. Cells do not posses intercellular spaces.
How does the cork act as a protective tissue Brainly?
Answer: Cork acts as a protective tissue because its cells are dead and compactly arranged without intercellular spaces. They have deposition of suberin on the walls that make them impervious to gases and water.
Which is called protective tissue?
epidermis tissue is also known as protective tissue .
What is the name of protective tissue?
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.
Which cell is called guard cell and why?
Explanation: Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. … … This turgidity is caused by the accumulation of K+ (potassium ions) in the guard cells.
What is cork cell and its function?
A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. The layer of dead cells formed by the cork cambium provides the internal cells of the plants with extra insulation and protection. …
What is cork and what are its function?
Cork is light weight and does not catch fire easily, due to these properties it is used in making insulators, shock absorbers and sports goods. They protect the plant from harmful microbes. They protect the plant form mechanical injuries. They prevent the loss of water by evaporation and transpiration.
