Question

__________ is polymorphic cell organelles.
A.Ribosome
B.Lysosome
C.Chloroplast
D.Nucleus

Answer 1

Hint: Polymorphism is defined by many forms of a particular trait/entity/genetic variant. Not every cell organelle contains different forms or shapes and can perform different functions. Now from the above concept you can think and assume which cell organelle consists of this kind of cell that produces different forms or shapes and performs different functions.

Complete answer:
To answer the given question, first, we should have knowledge about polymorphism. Polymorphism is defined as an irregular genetic variant developing in the formation of many different shapes or kinds of individuals in the members of a single species. An irregular genetic variant divides the members of a population into two or more clearly different forms. Polymorphic cells mean they are present e in more than one form.

Now let us find solution from given options:
A.Ribosome : They are of two types usually 70S and 80S but at one time they exists in only one form. They are usually involved in the synthesis of proteins.
B.Lysosome : Lysosomes are termed as polymorphic cell organelles. Actually, polymorphism is the presence in several different shapes particularly in reference to species or genetic variation. Lysosomes are present in more than one form inside the cell. There are two known types of lysosomes - primary lysosomes and secondary lysosomes.
C.Chloroplast : it is the main region of cellular activity. All the metabolic activities occur inside this. This is usually green in colour.
D.Nucleus : it is a structure that performs a role in the information carrying centre from one generation to another. It occurs only in one form.

Hence, the correct answer is option (B)

Note: Lysosomes are made up of acidic hydrolytic enzymes that simplify waste materials and cellular debris. They can be termed the stomach of the cell. Lysosomes eat excessive organelles, nutrient materials, and remove viruses or bacteria. The membrane enclosing a lysosome permits the protection.
