Nature of the Tissue. Often fibres are put in two groups, viz., intraxyllary fibres or wood fibres, and extraxyllary fibres, also called bast fibres. Tissue Cell Types Function Locations Vascular tissue Xylem is made up of vessels and tracheids Phloem is made up of sieve cells and companion cells […] simple tissue are the tissue which grow. Phloem Tissue. Secondary meristems usually originate in this type of cells. The fibres of ramie, Boehmeria nivea of family Urticaceae may measure as much as 55 cm. TYPES OF PLANT TISSUE Meristematic tissue Apical meristems Lateral meristems Intercalary meristems Permanent tissue Simple permanent tissue Parenchyma – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 3d8a05-NjA0O Plant Tissues Multiple Choice Questions and Answers for competitive exams. Homogenous: Heterogenous: Example. These are also known as homogenous tissues. Four of the five answers listed below are characteristic of monocots. Parenchyma is the most common ground tissue. All its cells are structurally and functionally similar. It is the tissue which makes the plant. The cells are … Epidermal cells of the roots, whose function is water absorption, commonly bear long hair-like parts that greatly increase the total absorptive surface area. 30 seconds . 1.

Each type of tissue consists of different types of cells, has different functions, and is located in different places. Identify the simple permanent plant tissue with the following descriptions and also mention their location in the plant body. answer choices . Fairly large air cavities may be present in the parenchyma cells of aquatic plants in particular, where the volume of cavities is often greater than that of the cells. Bodies of lower plants are made of parenchyma cells. It protects all the parts of the plant. In view of the fact that diverse types of cells may be elongated, the term prosenchyma has gone out of use. Normally paren­chyma cells are polyhedral in shape with profuse intercellular spaces. Answered Explain simple plant tissues 2 See answers The girth of the stem or root increases due to, As the cells of this tissue are very active, they have. They take up a specific role and lose the ability to divide. The growth of plants occurs only in certain specific regions. They have peculiarly overlapped or interlocked ends (Fig. Simple tissue have large distribution and superior tissue have restricted distribution. Answer: Parenchyma, collenchyma and sclerenchyma. State the 3 types of tissues in vascular plants. They are of three types:-1 Parenchyma 2 collenchyma 3 sclerenchyma . As already stated sclerenchyma is the most effective mechanical tissue of the plants. Functions ; The main function of this tissue is storage of food. Welcome to BiologyDiscussion! They are available in almost all parts of a plant. In plants, there are two types of tissues: meristematic tissue and permanent tissue. Meristematic tissues may be defined as a group or collection of living cells which ar located specific locations and divide continuously to add new cells to the plant body. PLAY. These short objective type questions with answers are very important for Board exams as well as competitive exams like NEET, AIIMS etc. Share Your PDF File Permanent tissue is of two types—simple permanent tissues, where all cells are similar in structure and function, and complex permanent tissues, which are composed of different types of cells. Simple tissues of Plant Parenchyma. Parenchyma occurs as homogeneous mass in many portions, but it may also be asso­ciated with other elements in complex tissues like xylem and phloem. 535) is also a simple tissue consisting of one type of elements. The type of plant cell which retains life even after attaining maturity is parenchyma. 536B). (ii) Lacunate or tubular collenchyma is the second type in which intercellular spaces are present and thickenings are restricted to the walls of the regions bordering on spaces (Fig. They are usually poly­gonal in cross-section. It mainly acts as a packing tissue, providing mechanical support. Chloroplasts may also be present. These short solved questions or quizzes are provided by Gkseries. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. answer choices . 30 seconds . Primary pit fields may be present. The epidermis is usually made of a single layer of cells. This tissue is normally absent in underground organs, though it may rarely occur in roots, particularly when they are exposed to light.
