<\/p>\n
Long Answer Questions<\/span><\/p>\nQuestion 1. \nWhat are meristematic tissues? State their characteristics with locations. \nAnswer: \nMeristematic tissues are tissues found at the meristematic regions i.e. growing regions in plants. Their cells have active protoplasm, with small or no vacuole, no chloroplasts but a large active nucleus. The cells are compactly packed with less or no intercellular spaces. The cells are mostly involved in division to form new cells which later undergo differentiation to from different cells to add to plant growth. \n \nMeristems on basis of its location has been classified into three types: \nApical meristem, present at the growing tips of stem and root. It contributes to vertical plant growth. \nIntercalary meristem, present at the base of leaves and internodes where they contribute to the branching of stem.<\/p>\n
Lateral meristem, present on the lateral side of stem and root in form of cambium. These meristems contribute to the growth in thickness i.e. increase in thickness or girth of stem and root.<\/p>\n
Question 2. \nState the functions of the different parenchymatous tissue. \nAnswer: \nParenchymatous tissue performs the following functions:<\/p>\n
\nThey mostly store and assimilate food material.<\/li>\n When in form of chlorenchyma in leaves and other green plant parts, they help in photosynthesis.<\/li>\n In aquatic plants, their cells bear large air cavities and hence, help provide the necessary buoyancy to the plant parts for floating in water.<\/li>\n They provide mechanical support also particularly the xylem parenchyma and pholem parenchyma.<\/li>\n<\/ul>\nQuestion 3. \nWhat are vascular bundles? State their functions. \nAnswer: \nVascular bundles are the bundles comprising of xylem and pholem.<\/p>\n
Xylem consist of four components: tracheids, vessel cells, xylem fibres and xylem parenchyma. Of these components, only xylem parenchyma is living the rest are the dead structures. Tracheids and vessels cells are tubular structures with a lumen to allow the transport of water and minerals from root to leaves. Their thick walls have pits too, for the lateral transport of water. \n \nPhloem consists of four components: sieve cells, companion cells, phloem parenchyma and phloem fibres. In these components, phloem fibres are dead and are meant to provide, mechanical strength to the tissue, while the rest are living structures. However, the sieve cells are live but lack nucleus and hence, they are always present along with companion cells. These cells perform cellular activities for sieve cells. The sieve cells or sieve tubes allow the bidirectional flow of food. \n <\/p>\n
Question 4. \nDescribe briefly the different types of epithelial tissues with their functions. \nAnswer: \nThe different types of epithelial tissues include: \n(i) Squamous epithelial tissue: Their cells are thin, flattened, polygonal like the tiles of floor. They form the outer layer of skin, tongue, esophagus and the inner lining of mouth. \n <\/p>\n
(ii) Cuboidal epithelial tissue: Their cells are mostly cuboidal in shape. They form the lining of kidney tubules and ducts of salivary glands. These cells provide mechanical support and if ciliated, they help in pushing the content forward such as in oviduct. \n <\/p>\n
(iii) Columnar epithelial tissue: Their cells are long column or pillar like. They form the inner lining of the intestine and if ciliated, they help in movement, such as in respiratory tract, the ciliated columnar epithelial cells help in pushing the mucus upward from lungs to mouth. \n <\/p>\n
(iv) Glandular epithelial tissue: Their cells are also columnar or cuboidal shape and involved in secretion of mucus and digestive enzymes and therefore are found in different body glands.<\/p>\n
<\/p>\n
Question 5. \nName the different types of connective tissues with their functions. \nAnswer: \nAreolar tissue: ft is present in between the skin and underlying muscles contains different types of cells that are responsible for the formation of different fibre types i.e. collagen fibres and elastin fibres. Some cells present also synthesize heparin, an anticoagulant and histamine.<\/p>\n
Tendon: These are white fibrous tissues which attaches the muscles to bones.<\/p>\n
Ligament: These are yellow fibrous tissues which attaches the two bones together at the point of their joint.<\/p>\n
Adipose tissue: This tissue underlying the skin stores excess of fats and provide insulation to the body.<\/p>\n
Blood is fluid connective tissue that helps in circulation of nutrients, metabolic waste, gases, etc in body along with providing the immunity or defense against any infection.<\/p>\n
Question 6. \nWhat are the different components of blood? What are their functions? \nAnswer: \nBlood is the fluid connective tissue that consists of blood cells found immersed in blood plasma. Blood plasma is the fluid part of blood. In blood three different cell types are found: RBC, WBC and blood platelets. \n \nRed blood cells(RBC) are carrier of haemoglobin and therefore responsible for the transport of oxygen from lungs to body parts.<\/p>\n
White blood cells(WBC) are either amoeboid shaped called phagocytes or large oval cells with large nucleus called lymphocytes. Phagocytes provide defense t engulfing the germs and lymphocytes provide defense by secreting antibodies: fight to invading germs.<\/p>\n
Blood platelets are small fragments like cells that are responsible for blood coagulation after the injury.<\/p>\n","protected":false},"excerpt":{"rendered":"
