Exercise 1<\/strong><\/span><\/p>\n

Solution A.<\/strong><\/span><\/p>\n

    \n
  1. (c) Parenchyma<\/li>\n
  2. (a) Fibrous connective tissue<\/li>\n
  3. (a)Meristem- Actively dividing cells<\/li>\n<\/ol>\n

    Solution B.1.<\/strong><\/span><\/p>\n

    (a) Apical or terminal meristematic tissue
    \n(b) Protective tissue
    \n(c) Columnar epithelium (Epithelial tissue)
    \n(d) Ligament (Connective tissue)
    \n(e) Conducting tissue
    \n(f) Sclerenchyma (Supporting tissue)<\/p>\n

    Solution B.2.<\/strong><\/span><\/p>\n

    Sclerenchyma composed of long, narrow and thick cells, which have become dead, forms the least specialized tissue in plants. This tissue forms the walls and boundaries of plant cells and provides strength to tissue plant parts.<\/p>\n

    Solution B.3.<\/strong><\/span><\/p>\n

    (a) Tissue
    \n(b) Permanent tissue cells
    \n(c) Cambium<\/p>\n

    Solution B.4.<\/strong><\/span><\/p>\n

    (a) Tips of roots
    \n(b) Nose
    \n(c) Lining of mouth
    \n(d) Veins of leaves
    \n(e) Lining of trachea
    \n(f) Bones<\/p>\n

    Solution B.5.<\/strong><\/span><\/p>\n

    (a) Squamous epithelium
    \n(b) Cuboidal epithelium
    \n(c) Neuron
    \n(d) Ciliated columnar epithelium<\/p>\n

    Solution C.1.<\/strong><\/span><\/p>\n

    Ciliated columnar epithelium is found in the lining of trachea. This epithelium has thread-like projections called cilia at their free ends. The cilia constantly keep lashing and move the materials which enter this organ.<\/p>\n

    Solution C.2.<\/strong><\/span><\/p>\n

    Nervous tissue or neurons are specialized group of cells. This tissue is concerned with perception and responses of animals.
    \nThe nervous tissue constitutes the     nervous system<\/a>, which is an organ system. It controls and coordinates all the systems of the body.<\/p>\n

    Solution C.3.<\/strong><\/span><\/p>\n

      \n
    1. Muscular tissue (Cardiac muscles)<\/li>\n
    2. Epithelial tissue (Lining of blood vessels of the heart)<\/li>\n
    3. Connective tissue (Fluid connective tissue in the form of red blood corpuscles)<\/li>\n<\/ol>\n

      Solution C.4.<\/strong><\/span><\/p>\n

      A tissue is a group of similar cells from the same origin that together carry out a specific function. An egg is a zygote or a cell but a cluster of eggs cannot be considered as a tissue as it does not form an organ like a tissue. Instead it gives rise to a new individual organism if gets fertilised.<\/p>\n

      Solution C.5.<\/strong><\/span><\/p>\n

        \n
      1. Striated muscles:<\/strong>\u00a0Provide the force for locomotion and all voluntary movements of the body. These muscles are found in the limbs.<\/li>\n
      2. Unstriated\u00a0muscles:<\/strong>\u00a0Provide movements for the passage of food in the intestines. These muscles are found in iris of the eye, lining of blood vessels, urinary bladder, etc.<\/li>\n
      3. Cardiac muscles:<\/strong>\u00a0Provide rhythmic contraction and relaxation movements. These muscles are found only in the heart.<\/li>\n<\/ol>\n
