Best answer: What is protective tissue in plants Class 9?

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 are protective tissues?

There are two kinds of protective tissues: the epidermis and the suber or cork. This chapter is devoted to the study of epidermis. The cytological structure of epidermal cells is quite variable, but this fact does not alter the histological and histochemical uniformity of the epidermal tissue.

What are protective tissues of plant name them?

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 protective tissue and its function?

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.

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.

What is the example of 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).

What are three types of protective tissues?

Protective Tissue

  • 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.

What is the role of protective tissue in plant?

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 the protection tissue of plant?

Epidermis, in botany, outermost, protoderm-derived layer of cells covering the stem, root, leaf, flower, fruit, and seed parts of a plant. The epidermis and its waxy cuticle provide a protective barrier against mechanical injury, water loss, and infection.

What is the main 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.

What is tissue made of?

A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

What is the main function of xylem tissue?

Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.

What are stomata Class 9?

Stomata are the small pores in leaves of plants. They act as lungs. Stomata take in carbon dioxide and give out oxygen during photosynthesis and visa versa during respiration, thus enabling the exchange of gasses.

What is permanent tissue?

Tissues that have become mature and do not have the ability to divide further are called permanent tissues. Permanent tissues are made up of cells that do not undergo cell division. The cells in these tissues are modified to perform some specific functions. … Permanent tissues are derived from the meristematic tissue.
