1) Tissue is a group of similar kind of cells specialized to perform a particular function in the body. Therefore presence of tissues in a multicellular organism ensures: a) Faster development b) Division of labour c) Higher reproductive potential d) Body strength 2) Given below is a diagram showing the structure of a neuron tissue. Choose the correct labeling for the parts A, B, C, D and E. a) A – Nucleus; B – Cell body; C – Dendrite; D – Axon; E – Nerve ending. b) A – Nucleus; B – Dendrite; C – Cell body; D – Nerve ending; E – Axon. c) A – Nucleus; B – Axon; C – Cell body; D – Dendrite; E –Nerve ending. d) A – Nucleus; B – Dendrite; C – Cell body; D – Axon; E – Nerve ending 3) While doing work and running, you move your organs like hands, legs, etc. Which among the following is correct? a) Smooth muscles contract and pull the ligament to move the bones b) Smooth muscles contract and pull the tendons to move the bones c) Skeletal muscles contract and pull the ligament to move the bones d) Skeletal muscles contract and pull the tendon to move the bones 4) Cardiac muscle is one of the three major types of muscles, the others being skeletal and smooth muscles. It is found in the walls and histological foundation of the heart. Which one of the following statements is not related to the cardiac muscles? a) They muscles show rhythmic contraction and relaxation throughout life. b) They do not work according to our will, so they are called involuntary muscles. c) They are non-striated, multinucleated and branched muscles. d) The contraction and relaxation of the heart muscles help to pump and distribute blood to different parts of the body. 5) Xylem is the specialized tissue of the plants that transports water and nutrients from the soil to the upper parts like stems and leaves of plant and provides mechanical support to them. It is composed of four different types of the cells. Which of the following is not one a type of cell found in xylem tissues? a) Tracheids b) Vessels c) Xylem parenchyma d) Sieve tubes 6)  A person met with an accident in which two long bones of his hand were dislocated. Which among the following may be the possible reason for this? a) Tendon breaks b) Break of skeletal muscles tissue c) Ligament breaks d) Areoelar tissue breaks 7) Tiny pores are found on the surface of the leaves of plants. These pores are called stomata. These stomata surrounded by the kidney shaped guard cells provide many vital functions to the plants. Which of the following functions is not served by the stomata for the plants? a) Exchange of gases, particularly CO2 and O2, with atmosphere b) Loss of water in the form of vapours during transpiration c) Helps to create pressure for the water to rise upward, by its process of transpiration d) Helps the leaves to carry out the process of photosynthesis 8) Epithelial tissue always has an exposed outer surface and an inner surface anchored to connective tissue by a thin, non- cellular structure called the a) Non stratified layer b) Stratified layer c) Basement membrane d) Fibroblast 9) Meristemetic tissues are those which help in increasing the length and girth of the plan. Which of the following statements given below is correct about the meristematic tissue? a) It is made up of cells that are incapable of cell division b) It is made up of cells that are capable of cell division c) It is composed of single type of cells d) It is composed of more than one type of cells 10) Simple epithelium is a tissue, which form the outer protective layer of the skin of the animal body, is composed of cells which are a) Hardened and provide support to organs b) Continuously diving to provide to form an organ c) Cemented directly to one another to form an irregular layer d) Loosely connected to one another to form an irregular layer
