Tissues Class 9 Extra Questions Very Short Answer Type. Conjunctive parenchyma: Ø They form the conjunctive tissue of the stele of roots. Such type of parenchyma tissue is called chlorenchyma. This tissue is “functional” – performing tasks such as photosynthesis in plants or storing information in the human brain – as opposed to “structural” tissues like wood in plants or bone in animals.. Parenchyma tissues are found in the soft parts of plant such the roots, stems, leaves and flowers. Extra Questions for Class 9 Science Chapter 6 Tissues with Answers Solutions. Parenchyma Definition. Page 73. ii. These are dead and thick walled cells. Medullary parenchyma: Ø Medullary parenchyma occurs in the medullary ray of primary vascular tissue of stem.. Ø They are radially elongated cells with very thin walled cells.. Ø They allow radial condition of water and minerals. The cells in this tissue are loosely packed, as they contain large intercellular spaces between them. 1. Free Botany- Plant Anatomy PPT (Power Point Presentation): Structure, Classification and Characteristics of Parenchyma in Plants. (5). i. Prosenchyma: it is long and tapering parenchymatous cell present in some plants. → Parenchyma provides turgidity to cells. Parenchyma and Sclerenchyma Tissues Parenchyma Tissue. Name any two types of simple permanent plant tissues. Answer: Simple permanent tissues are of three types: (1) Parenchyma (2) Collenchyma (3) Sclerenchyma. The cells consist of cytoplasm and nucleus that is surrounded by a cell wall. • This tissue provides support to plants. XYLEM. Parenchyma is a term used to describe the functional tissues in plants and animals. Chlorenchyma and Aerenchyma CBSE Ncert Notes for Class 9 Biology Tissues. Eg pericylce. The parenchyma also acts as a storage tissue for food, air and water. • When the parenchyma cell contains chlorophyll in some situations, it performs photosynthesis. Parenchyma may be compact or have extensive spaces between the cells. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. Ø They can also store starch grains. Parenchyma tissue is the most abundant type of tissue in plants. CBSE Class 9 Science Chapter 5 Tissues Exercise Questions with Solutions to help you to revise complete Syllabus and Score More marks. Types of parenchyma tissue. Different types of tissues perform different function.It is because of this division of labour that multicellular organisms are able to perform all functions efficiently. → Chloroplast containing parenchyma tissue are chlorenchyma which perform photosynthesis such as mesophyll of leaves. The tissue is composed of living cells, with various shapes, sizes and functions. Functions of parenchyma are as follows: • It serves as food storage tissue. (6).
