Therefore, the response that is right is ″Epidermis and Cork.″
What are external protective tissues of plants of dicot stem?
Epidermis and cork are the two types of protective tissues that are found on the stems of dicot plants. (1) During extrastellar secondary growth, cells in the epidermis, pericycle, parenchyma, or collenchyma can acquire secondary meristematic properties through a process known as dedifferentiation; these cells are referred to as the phellogen or cork cambium.
What is the function of the protective tissue in plants?
A helpful hint is that the tissues that protect the plant body, such as the leaves, stems, and roots, are often located on the outermost layer of the plant body. They are responsible for providing the plant body with protection. They protect plants from drying out, being damaged by mechanical forces, and catching infections.
What is the function of the epidermis in a plant?
The cells that make up the epidermis form a covering that shields the plant’s leaves, buds, roots, and stems from outside elements. There is a clear demarcation between the inside of the facility and the outside environment. The cork cambium is a kind of tissue that is found in many vascular plants and functions as a component of the epidermis.
Which of the following is a Protecton tissue?
The epidermis and the periderm are the two primary layers of protective tissue. The organs that are covered by primary growth are covered by the epidermis, while the organs that are covered by secondary growth are covered by the periderm. It has been suggested by a few writers that the hypodermis and endodermis are protective tissues.
What are the protective tissues in plants?
Epidermis and cork are the two components that make up a plant’s defensive tissues (phellem).
Which are the external protective tissues of the plant Mcq?
- The following are examples of external protecting tissues: A. the cortex and the epidermis
- B. The pericycle and the cork
- C. The cortex as well as the pericycle
- D. The bark and the top layer of skin
What is the outer protective tissue in tree?
The epidermis is the most superficial layer of a plant’s body, and can be found on the leaves, flowers, stem, and roots, among other places.
Which tissue is protective tissue?
- The epidermis and the suber, sometimes known as cork, are the two types of protective tissues that exist.
- The epidermis is the topic that will be covered in this chapter’s research.
- Even while the cytological organization of epidermal cells might vary quite a bit from cell to cell, the histological and histochemical homogeneity of epidermal tissue does not change as a result of this variability.
What are protective tissues in plants Class 9?
Epidermis and cork are two examples of the protective tissues found in plants (phellem). Epidermis It is the coating that is found on the outside of plant cells. It serves a purpose in terms of protection (protecting plants from some adverse conditions). Typically, it consists of a single layer of cells throughout its entirety.
Which of the following is a protective tissue 1 cork 2 Chlorenchyma 3 phloem 4 xylem?
Because of the way its cells are structured and the fact that there are no intercellular gaps, cork functions as a tissue that provides protection. Because they contain a deposition of suberin on the walls, gases and water are unable to pass through them.
What is cork cambium and vascular cambium?
- After the tissues that make up the basic plant body have differentiated, secondary meristems such as the vascular cambium and the cork cambium may be found forming in the stems and roots of the plant.
- The vascular cambium is the structure in plants that is responsible for expanding the diameter of stems and roots as well as the formation of woody tissue.
- The cork cambium is responsible for the production of portion of the bark.
Which of the following is a protective tissue * parenchyma cork collenchyma Chlorenchyma?
Explanation: The outermost layer of the body, which includes the leaves, stem, and roots, has a tissue that functions as a protective barrier.
Where are Casparian strips found?
Casparian strips are a type of cellular structure that are present in the roots of all higher plants. They take the form of hydrophobic rings and are imbedded in the cell wall. These impregnations take place in the endodermis, which is a cell layer on the inside of the root that surrounds the primary vascular thread (Figure 1).
Is xylem a tissue?
The tissue of vascular plants known as xylem is responsible for transporting water and nutrients from the roots to the stems and leaves of the plant.
What are the tissues in the stem?
- Dermal, vascular, and ground tissue are the three types of tissue systems that make up the stem.
- The surface of the plant is made up of a tissue called the dermis.
- Epidermal cells, stomata, guard cells, and trichomes are all components of this structure.
- Xylem and phloem tissues combine to form vascular tissue, which is responsible for transporting water, minerals, and the results of photosynthesis.
Are the external protective?
The defensive tissues that are found in the body’s outermost layer are referred to as the body’s external protective tissues. Examples of external protective tissues are the stems, roots, and leaves of plants. They defend the body against a variety of threats, including infections, dehydration, trauma, and so forth.
