Question

Which of the following cells do not form a layer and remain structurally separate?
A)Epithelial cells
B)Muscle cells
C)Nerve cells
D)Gland cells

Answer 1

Hint: Cells are defined as the basic structural and functional unit of life. Each cell is organised to perform different functions. The different shape and size of cells make it possible for animals and plants to perform different functions.

Complete answer:
A branch of biology that helps with the study of the structure and function of the cell is called cell biology. The cell is defined as the basic and fundamental unit of life that collectively forms a tissue. Groups of cells that possess the same shape and size are clustered with each other to form a tissue performing a particular function.

Now let us find solution from given options:
Epithelial cells : Epithelial cells help to make the lining of the surface of the body. These are located in the external and internal exposed parts of the body. These cells are located upon a non-cellular Supporting layer which is termed as the basement membrane.
Muscle cells : Muscle cells are located in the muscles and these are essential for the movement of the body and various parts. These cells are also termed as myocytes or sarcocytes.
Nerve cells : Nerve cells or brain cells are the longest cells of the body. These help to make the structural and functional unit of the nervous system. These nerve cells do not form any layer and these are structurally separate.
Gland cells : Gland cells are present in many different glands of the body and these are connected with cellular secretion of various substances.

Hence, the correct answer is option (C)

Note: Neurons are also termed as the nerve cells are a highly active component of the nervous system. The main function that is performed by neurons is to communicate with each other and also with other cells through electronic signals or nerve impulses from the brain to the body and also back which means they transmit nerve impulses.
