Structural Organization in Animals NEET Biology MCQ with Answers

The structural organization in animals starts at the cellular level and progresses to tissues, organs and organ systems. Cells are the basic units of life and similar cells group together to form tissues. There are four main types of tissues in animals: epithelial, connective, muscle and nervous tissues. Epithelial tissue covers the body and lines organs and cavities, while connective tissue provides support and binds other tissues. Muscle tissue is responsible for movement and nervous tissue transmits signals throughout the body.

These tissues combine to form organs, which are specialized structures that perform specific functions. For example, the stomach is an organ that aids in digestion. Multiple organs work together to form organ systems, such as the digestive system, which includes the mouth, esophagus, stomach and intestines. Understanding the structural organization of animals is important for NEET students as it forms the foundation for comprehending more complex biological processes and systems.

Structural Organization in Animals NEET Biology MCQ

Understanding the structural organization in animals is important for NEET aspirants as it forms the foundation of anatomy and physiology. This topic covers the hierarchical organization from cells to tissues, organs and organ systems. A clear grasp of these concepts is essential for comprehending more complex biological processes and how different parts of the body function and interact.

Moreover, the NEET syllabus places significant emphasis on the structural organization because it is integral to understanding human biology, which is a major component of medical studies. Topics such as epithelial tissue, connective tissue, muscle tissue, and nervous tissue are frequently tested.

MCQs

Q1. Tissue is
A) a group of similar cells together with their intercellular substances, which perform a specific function
B) a single specialised cell with specified functions
C) composed of a single layer of cuboidal cells
D) Both (a) and (c)
Answer. A
Q2. In a tissue, the structure of cells varies according to their
A) origin
B) function
C) gene content
D) None of these
Answer. B
Explanation: (b) The structure of the cells varies according to their function. Based on their functional activity, tissues are broadly classified into four types, i.e. epithelial, connective, muscular and neural.
Q3. Which of the following tissues provide a covering layer for some of the body parts?
A) Connective tissue
B) Muscular tissue
C) Epithelial tissue
D) Neural tissue
Answer. C
Explanation: (c) Epithelial tissue has a free surface, which faces either inside the body, in vicinity with body fluid or the outside environment. Thus, it provides a covering layer for some parts of the body.
Q4. Lining of body cavities, ducts and tubes are made up of
A) compound epithelium
B) simple epithelium
c) cuboidal epithelium
D) keratinised epithelium
Answer. B
Explanation: (b) Simple epithelium is composed of a single layer of cells and it forms the lining of the body cavities, ducts and tubes.
Q5. Which of the following is not a function of epithelium?
A) Protection
B) Connection
C) Secretion or Excretion
D) Absorption
Answer. B
Explanation: (b) Providing connection between adjacent cells is not the function of epithelium tissue. It is the function of connective tissue.
Q6. The cells of squamous epithelium are
A) multilayered and thick
B) flat and thick
C) thin with rigid boundaries
D) flat with irregular boundaries
Answer. D
Explanation: (d) The squamous epithelium is made up of single, thin layer of flattened cells with irregular boundaries.
Q7. The endothelium of blood vessels is made up of simple
A) cuboidal epithelium
B) squamous epithelium
C) columnar epithelium
D) non-ciliated columnar epithelium
Answer. B
Explanation: (b) The simple squamous epithelium is present at the pericardial, perineural and peritoneal cavities, terminal bronchioles, air sacs, etc. In cavities like blood vessels and lymph vessels, it is called endothelium.
Thus, the endothelium of blood vessels is made up of simple squamous epithelium.
Q8. Choose the correctly matched pair.
CBSE-AIPMT 2014
A) Inner lining of salivary ducts-Ciliated epithelium
B) Moist surface of buccal cavity - Glandular epithelium
C) Tubular parts of nephrons-Cuboidal epithelium
D) Inner surface of bronchioles-Squamous epithelium
Answer. C
Explanation: (c) The pair in option (c) is correctly matched.
Other pairs are incorrect and can be corrected as
Inner lining of salivary ducts is lined by compound epithelium.
Moist surface of buccal cavity is lined by compound epithelium.
Inner surface of bronchioles is lined by ciliated epithelium.
Q9. The columnar epithelium in human body is found in
A) stomach
B) lungs
C) kidney
D) Fallopian tube
Answer. A
Explanation: (a) The columnar epithelium is composed of a single layer of tall and slender cells which possess microvilli on their free surfaces. These are found in the lining of the stomach and intestine and help in secretion and absorption.
Q10. Identify the given diagram of tissue performing the functions like secretion and absorption.
AllMS 2019
A) Simple cuboidal epithelium
B) Simple columnar epithelium
C) Stratified cuboidal epithelium
D) Stratified columnar epithelium
Answer. A
Explanation: (a) The given diagram is that of simple cuboidal epithelium as it has a free surface and is composed of a single layer of cube-like cells resting on the basement membrane. These are compactly packed with little intercellular spaces.
