1. Tissue that contains fibroblasts and a great deal of intercellular substance is (a) connective tissue (b) muscle tissue (c) nervous tissue (d) pseudostratified epithelium (e) simple squamous epithelium
Introduction: A group of closely associated, similar cells that carry out specific functions is known as tissue. Each kind of tissue is used to perform specific functions and is composed of specialized cells which have specific sizes, shapes, and arrangements. Animal tissues are classified into four major categories such as epithelial tissue, muscle tissue, connective tissue, and nervous tissue .
Answer to Problem 1TYU
Correct answer: Connective tissue contains few cells as compared to other tissues and are mainly composed of fibroblasts and a great deal of intercellular substance. Hence, the correct answer is option (a).
Explanation of Solution
Reason for the correct answer:
Cells of connective tissue are embedded in an extensive intercellular substance. As compared to epithelial tissue, they contain relatively few cells and a lot of fibroblasts and intercellular substances. Connective tissue is mainly composed of collagen, elastic and, reticular fibers.
Option (a) is given as “connective tissue”.
Cells of connective tissue are embedded in an extensive intercellular substance and contain relatively few cells. Hence, the correct answer is option (a).
Reason for incorrect answer:
Option (b) is given as, “muscle tissue”.
Muscle tissue is made up of muscle cells which are connected together in the form of sheets. Therefore, it has less intercellular space. Hence, option (b) is incorrect.
Option (c) is given as, “nervous tissue”.
Nervous tissue is made up of neuron and neuroglia cells. Nervous tissue takes part in communication and therefore, there is not much intercellular space. Hence, option (c) is incorrect.
Option (d) is given as, “pseudostratified epithelium”.
The main function of pseudostratified epithelium is to protect underlying tissues. It also lines some of the respiratory passageways. Therefore, no intercellular substances are present due to the lack of intercellular spaces. Hence, option (d) is incorrect.
Option (e) is given as, “simple squamous epithelium”.
Simple squamous epithelium cells are present in the locations of secretion, absorption, and excretion (such as lungs, kidneys). They act as barriers and do not have intercellular spaces. Hence, option (e) is incorrect.
Hence, the options (b), (c), (d), and (e) are incorrect.
Connective tissue contains fibroblasts and a great deal of intercellular substance.
