  • Question 1
    1 / -0

    Match the following with correct response.

    (1) Tendons
    (2) Ligaments
    (3) Cartilage
    (4) Bones

    (A) Osteocytes
    (B) Yellow fibres
    (C) White fibres
    (D) Chondriocytes

    Solution

    Tendons  are white fibrous tissue. Ligaments are the modification of yellow elastic tissue with some collagen fibres.Chondrocytes are the only cells found in healthy cartilage. The osteocyte is the most abundant cell type of bone.

     

  • Question 2
    1 / -0

    Match the following with correct response.

    (1) RBC
    (2) Striated muscles
    (3) Smooth muscles
    (4) Axon

    (A) Alternate light & dark bands
    (B) Neuron
    (C) Uninucleate
    (D) Transport oxygen

    Solution

    The primary function of red blood cells is to transport oxygen from the lungs to the cells of the body. Striated muscles contain alternate light and dark bands.Smooth muscles is composed of uninucleate cells. An axon is a long, slender projection of a nerve cell, or neuron.

     

  • Question 3
    1 / -0

    Function of areolar tissue is

    A. it supports internal organs
    B. It stores fat
    C. It helps in repair of tissues
    D. It protects internal organs

    Solution

    Areolar Tissue:  It consists of matrix, several types of cell, collagen and elastin fibres. They are found between the skin and the muscles around blood vessels and nerves  and in the bone marrow.

    Function of areolar tissue are

    (a) It fills the space inside the organ.
    (b) It supports the internal organ.
    (c) It helps in the repair of the tissues.

     

  • Question 4
    1 / -0

    Name a basic tissue present in plants but absent in animals.

    A.Meristematic tissue
    B.Epithelial tissue
    C.Connective tissue
    D.Muscular tissue

    Solution

    Animal body is made of four different types of tissues.
    (i) Epithelial Tissue (ii) Muscle Tissue (iii) Connective Tissue (iv)     Nerve Tissue
    Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.
    So, Meristematic tissue is present in plant cells but absent in animal cells.

     

  • Question 5
    1 / -0

    Which of the two statements is true?

    Statement A: Collagen occurs in yellow elastic fibre.
    Statement B: Sclereids form gritty part of ripe fruits.

    Solution

    Collagen is actually a group of proteins found naturally in the body. Elastic or yellow cartilage contains elastic fiber networks and collagen fibers.
    Sclereids form the gritty part of most of the ripe fruits and contribute hardness to the seed coat and nutshells.
    Statement A and B are true statements.

     

  • Question 6
    1 / -0

    Which of the two statement is true

    Statement A: Cuboidal epithelium is located in salivary glands.
    Statement B: Collenchymas are lignified elongated dead cells.

    Solution

    Cuboidal epithelium is located in salivary glands. Collenchyma are simple permanent tissue thickened at the corner of the cells but they are not lignified, elongated and dead cells.

     

  • Question 7
    1 / -0

    Match the following with correct response.

    (1) Parenchyma
    (2) Phloem
    (3) Stomach
    (4) heart

    (A) Conduct prepared food
    (B) Muscular tissue
    (C) An organ
    (D) Storage of food in plants

    Solution

    Parenchyma is a thing that store food in plants. Phloem conduct prepared food in plants. Stomach is an organ. Heart is a muscular tissue.

     

  • Question 8
    1 / -0

    Match the following with correct response.

    (1) Root tip
    (2) Cell
    (3) Blood
    (4) Living organisms

    (A) Fluid connective tissue
    (B) Consist of meristematic tissue
    (C) Grow & Reproduce
    (D) Structural & functional unit of life

    Solution

    Root tip consists of meristematic tissue. Cell is a structural and functional unit of life. Blood is a fluid connective tissue. Living organisms grow and reproduce.

     

  • Question 9
    1 / -0

    Upper and lower layer of cells in leaves

    A. Protect the inner parts
    B. Synthesise food
    C. Regulate the water content
    D. Exchange the gases

    Solution

    1) Leaves have an outer layer that protects them. This outermost layer is called the cuticle. It is generally waxy to protect the leaf and prevent water loss.
    2) Network of veins support the leaf and transport water and carbohydrates
    3) Guard Cells surrounding stomata that control rate of gas and water exchange. Stomata  opening between guard cells for gas and water exchange.
    So,  (a), (c) and (d) are function of upper and lower layer of cells in leaves.

     

  • Question 10
    1 / -0

    The cells that do not lose their nucleus at maturity are-

    A. Red blood cells
    B. Vessel cells
    C. Companion cells
    D. Parenchymatous cells

    Solution

    Among these four only companion cells have nucleus. Other three cells do not have nucleus in maturation. Companion cells is the cell that does not loses their nucleus at maturity.
