D. R, P, Q, S

Answer 1

Hint: There are numerous organelles in living cells, such as cytoplasm, chloroplast, nucleus, mitochondria, etc., and all of these organelles have different structures and functions that work together to make the cell live.

Complete answer: The organelle chloroplast is a double membrane-bound organelle. The organelles found in the rough endoplasmic reticulum are ribosomes. It consists of proteins and RNA and consists of two subunits; the smaller one is involved in the binding of messenger RNA and the larger subunit is involved in the inclusion of amino acids. The nucleus consists of the network of RNA, DNA, and protein, nucleolus, and chromatin, next is the mitochondria that is called the cell's powerhouse as it stores energy in the form of ATP molecules, Golgi bodies are sac-like vesicles, and cisternae have a cis and trans face, the endoplasmic reticulum is a membrane network involving ribosomes during the process of translation. The lysosome is the organelles involved in the digestion of cells consisting of enzymes, so it reflects polymorphism as it has different forms and acts by breaking down the junk portion of the cell. Now let us look at the individual size of each organelle to get the correct answer,
R- A nucleus is around \[6\}\mu m\] in dimension.
P- The chloroplasts are \[3\text{ }\mu m\] in size.
S- The lysosomes are \[{{0.1}}\mu m\] in size.
Q- The ribosomes are around \[0.02\text{ }\mu m\] in size.
Thus, choice C- R, P, S, Q is the correct answer.

Note: It may be confusing that ribosome also shows polymorphism since it has two subunits, one for messenger RNA and one for amino acid, but it should be clear that polymorphism indicates multiple variants of a single entity that is only seen in lysosomes.
