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.
Which tissues are protective?
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.
How many protective tissues are there?
4 Protective Tissues. Protective tissues are divided into two parts: Epidermis.
Which tissue gives protection to the plant body?
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 protective tissue in the body?
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 nervous tissue with diagram?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. … The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
Is a 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. Types of protective tissues: Epidermis.
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.
What are the 4 types of plant tissues?
Plant tissues come in several forms: vascular, epidermal, ground, and meristematic. Each type of tissue consists of different types of cells, has different functions, and is located in different places.
Which plant tissue has the most important function?
Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions, and soluble food substances throughout the plant.
