  • Question 1
    1 / -0

    Which of the following tendons connect?

    Solution

    Tendons are connective tissues which connect the muscles to bones. A tendon is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension. Tendons are similar to ligaments. Ligaments join one bone to another bone. Tendons and muscles work together to move bones.

    Which of the following is also known as conducting tissue?

  • Question 3
    1 / -0

    Which of the following is not lined by the columnar epithelium?

    Solution

    The columnar epithelium is found in the intestines, stomach and gall bladder. The alveoli are lined by simple squamous epithelial cells. Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudo stratified columnar epithelium with goblet cells. Bronchioles are lined by simple cuboidal epithelium. (Lung alveoli, in contrast, are lined by very thin simple squamous epithelium.)

  • Question 4
    1 / -0

    Which of the following is absent in RBC?

    Solution

    Nucleus is absent in RBC. The absence of a nucleus is an adaptation of the red blood cell for its role. It allows the red blood cell to contain more haemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion.

  • Question 5
    1 / -0

    Phloem consists of _________.

    Solution

    Phloem consists of living cells, primarily sieve tube cells and companion cells. Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids.

  • Question 6
    1 / -0

    A group of similar cells to perform a specific function forms a

    Solution

    Because the cells are not only similar but the function that they perform is also same, that is why they together become a tissue. Tissues are made of cells of the same type. The basic unit of life, Cell.  A group of similar cells that together perform a specific function in an organism, Tissue.

  • Question 7
    1 / -0

    Which of the following helps in making up Living organisms ?

    Solution

    A cell is the basic building block of all organisms and thus all the living organisms are made up of the cell. It is the smallest unit of organization in a living thing. The cell group together to form tissues and tissues group together to form organ and then to organ system and organism.

  • Question 8
    1 / -0

    Fluid connective tissue of humans is

    Solution

    Blood and lymph are fluid connective tissues. Cells circulate in a liquid extracellular matrix. Nutrients, salts, and wastes are dissolved in the liquid matrix and transported through the bodyLymph contains a liquid matrix and white blood cells.

  • Question 9
    1 / -0

    Which of the following makes up an organ?

    Solution

    Tissues together make up an organ. Every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task. Humans—and other large multicellular animals—are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

  • Question 10
    1 / -0

    Characteristics present in meristematic cells are

    Solution

    Meristematic cells are actively dividing undifferentiated cells present at different locations in a plant body which helps in the primary (apical and intercalary meristem) and secondary growth (lateral meristem) in plants.

    The characteristics of meristematic cells are:-

    1)The cells are isodiametric with thin cellulosic cell walls with no secondary cell wall.

    2) They divide rapidly hence, there is no stored food in these cells.

    3) They are compactly arranged cells with no intercellular spaces.

    4) They have a dense cytoplasm with a prominent nucleus.

    5) Endoplasmic reticulum and mitochondria are not fully developed in these cells.

    6)  They are the most metabolically active cells.

    So, the correct answer is 'Thin wall, dense protoplasm, no intercellular spaces, isodiametric and nucleate'.
