Answer: Question 9. The parenchyma is present in all the organs of the plants, i.e., roots, stems, leaves, flowers, fruit and seeds. The place of injury in plants is healed up by the formation of new cells by meristems. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. Unlike collenchyma, mature cells of this tissue are generally dead and have thick walls containing lignin. Parenchyma serves as packing tissue to fill the spaces between other tissues. Study Material and Notes of Ch 6 Plant Tissues Class 9th Science. For example: cork cambium. The matrix may be jelly like, fluid, dense or rigid. Each cell has a vacuole at the center. (b) thickness of cell wall. Cells of epidermis are elongated,flattened,do not contain any intercellular spaces between them. 1)They provide mechanical support and elasticity to dicotyledonous stem. They are dead cells,do not have protoplasm.Walls are greatly thickened with deposition of lignin(chemical substance which act as cement and hardens them).Cells are closed packed without intercellular spaces. Write the location and function of collenchyma tissue. Connective tissue binds other tissues together in the organs. Parenchyma is a term used to describe the functional tissues in plants and animals. The parenchyma stores food and helps in the sideway conduction of water. Question 1. As a result of improved organization and higher efficiency, multicellular organisms have higher survival. Question 6 Explain the structure of stomata?

Students can download the last year question papers using the link below. It is also concerned with body defense, fat storage, repair etc. The covering or protective tissues in the animal body are animal tissues. Cork cells are dead,compactly arranged,no intercellular spaces,rectangular,vacuolated. Ø Sclerenchymatous cells are dead at their maturity. (d) unstriated muscle. Your email address will not be published. 1)They serve as a packing tissue and fill the spaces between other tissue. Karnataka Board Class 9 Science Chapter 6 Tissues KSEEB Solutions for Class 9 Science Chapter 6 Intext Questions Question 1. Cross striations and intercalated disc present. Vessels or tracheae   3. Class 9 Biology Tissues: Parenchyma: PARENCHYMA. The cells have dense protoplasm with prominent nuclei. It is also used for making sports goods, such as shuttle-cock, table tennis paddles, crcket balls, etc. Question 4 What is the function of stomata? (a) Seive cells (b) Seive tubes (c) Phloem fibres (d) Phloem parenchyma. These are. They appear at the periphery of roots and stems when they grow older and increase in girth. It is a simple permanent tissue, having chloroplast. It fills the space inside the organs, supports internal organs and helps in the repair of tissues. These tissues take part in growth by formation of new cells. It is the chief component of ligaments and tendons. Which of the following tissues has dead cells? It consists of tall, cylindrical, pillar-like cells. CBSE NCERT Solutions for Class 9 Science Chapter 6 . Stomata allows exchange of gases during respiration and photosynthesis,during transpiration too,water vapour also escape through it. Parenchyma . Since walls of tracheids, vessels and sclerenchyma of xylem are lignified, they give mechanical strength to the plant body. Present in limbs, tongue, body wall and pharynx. Question 7 Name two types of permanent tissue? Tracheids   2. Cartilage provides support and flexibility to the body parts. In xerophytic or desert plants,cuticle is thick and protect again water loses. Name the following: (A) Tissue that forms inner lining of our mouth. Q8: Which of the followings lack vacuoles in their cytoplasm ? Parenchyma is found in all parts of plant such as cortex, pith, palisade, mesophyll, flower, seed etc; It is also found in vascular tissues. Cells may be cuboidal or columnar and are, therefore , also called ciliated cuboidal epithelium or ciliated columnar epithelium. The “tissue” is very crucial in order to understand Biology topics in Class 10 and in higher secondary classes. This tissue is responsible for movement in our body. structure , function, location of parenchyma, collenchyma, sclerenchyma, xylm and phylomen tissue ????? It consists of relatively unspecialised cells with thin cell walls. The cells consist of cytoplasm and nucleus that is surrounded by a cell wall.
