CBSE/NCERT BIOLOGY 11 CHAPTER 07: STRUCTURAL ORGANIZATION IN
ANIMALS QUESTIONS WITH CORRECT ANSWERS

Tissue - CORRECT ANSWER -A group of cells with a common origin, structure, and function



Who coined the term tissue? - CORRECT ANSWER -Francois Xavier Bichat, father of modern
histonology



Histology - CORRECT ANSWER -study of tissues



How many types of animal tissues are there? - CORRECT ANSWER -Four



What are the four types of tissues? - CORRECT ANSWER -epithelial, connective, muscle, nervous



epithelial tissue functions - CORRECT ANSWER -covering tissue, protects underlying tissues,
storage of materials, diffusion, absorption, secretion, etc.



Connective tissue - CORRECT ANSWER -connects, supports, penetrates, and encases various
body structures



Muscular tissue - CORRECT ANSWER -locomotion and movement



Nervous tissue - CORRECT ANSWER -Coordinates, regulates, and integrates body functions



Origin of epithelial tissue - CORRECT ANSWER -ectoderm, mesoderm, endoderm



How much intercellular space is in epithelial tissue? - CORRECT ANSWER -little to none

,How do cells in epithelial tissues communicate? - CORRECT ANSWER -cell junctions



Basement membrane - CORRECT ANSWER -Cells at the base of an epithelial layer are attached
to this noncellular



non-vascular/avascular tissue - CORRECT ANSWER -Tissue that does not receive direct blood
supply



Is epithelial tissue vascular or avascular? - CORRECT ANSWER -avascular



How does epithelial tissue get nutrients? - CORRECT ANSWER -Diffusion from underlying
connective tissue



Location of epithelial tissue - CORRECT ANSWER -body coverings, body linings, glandular tissue



How is epithelial tissue classified? - CORRECT ANSWER -number of layers and shape



simple epithelium - CORRECT ANSWER -single layer of cells



compound epithelium - CORRECT ANSWER -different layers of cells



squamous epithelium - CORRECT ANSWER -flat, scale-like cells



Where is squamous epithelium found? - CORRECT ANSWER -areas specialized for diffusion such
as alveoli, air sacs, blood capillaries, etc., also epidermis



function of squamous epithelium - CORRECT ANSWER -diffusion and filtration

endothelium - CORRECT ANSWER -the specialized squamous epithelial tissue that lines the
blood and lymph vessels and heart



Pavement epithelium - CORRECT ANSWER -squamous epithelium

Brush bordered cuboidal epithelium - CORRECT ANSWER -specialized cuboidal cells lining
proximal convoluted tubule, have microvilli



Microvilli - CORRECT ANSWER -Fingerlike extensions of plasma membrane of apical epithelial
cells, increase surface area, aid in absorbtion, exist on every moist epithelia, but most dense in
small intestine and kidney



germinal cuboidal epithelium - CORRECT ANSWER -thick layer of cells that covers the sex organs
during the early developmental stage of the embryo



Pigmented cuboidal epithelium` - CORRECT ANSWER -epithelial cells that are highly pigmented
due to the numerous large melanosomes which pack the cytoplasm of each cell, found in layer
just behind iris



columnar epithelium - CORRECT ANSWER -Single layer column shaped cells
