Question

The cell organelles showing extensive polymorphism is
(A) Dictyosome
(B) Chloroplast
(C) Lysosome
(D) Ribosome

Answer 1

Hint: Living cells have different organelles like cytoplasm, chloroplast, nucleus, mitochondria, etc. and all these organelles have different structure and function that work together to make the cell live.

Complete answer:Cell organelles are small organ-like structures with specific function.
The mitochondria and chloroplast are organelles that are double membrane bound. The outermost layer of the cell is cell membrane, it is selectively permeable that allows the movement of materials in or out of the cell. Below the cell membrane, a cell wall is present but it is only found in plant cells, it is also permeable in nature, and made of cellulose and peptidoglycan.
Cytoplasm is the next part of the cell that contains 90 percent of water and organic and inorganic compounds; it is colloidal and viscous in nature, and jelly like fluid inside the cell. The nucleus is composed of RNA, DNA, and protein, nucleolus, and chromatin network, next is the mitochondria that is considered as the power house of the cell as it stores energy in form of ATP molecules, golgi bodies is a sac-like vesicles and cisternae has cis and trans face, the endoplasmic reticulum is a membrane network that have rhibosomes involve during translation process.
Lysosome is the organelles involved in the cell digestion composed of enzymes hence, breaking down of the junk component of the cell, it shows the polymorphism as it has different shape and functions.

Now lets us find the solution from the given options:
1. Dictyosomes have membrane bound cavities that look like stacks of flat and together comprise the golgi apparatus. They do not show polymorphic character.
2. Next,chloroplast is the organelles found in plants, it is the site where photosynthesis takes place. It converts light energy into chemical energy. Its structure consists of an inner membrane and outer membrane with intermediate empty space.
3. Lysosomes in primary stages termed as proto lysosomes, heterolysosomes or heterophagosomes are formed by primary lysosome and phagosome fusion. The autophagic lysosome involved in autophagy. The heterolysosomes, residual lysosome, and autophagic lysosome form the secondary lysosomes.
4. Ribosomes are the organelles found in rough endoplasmic reticulum. It is made of proteins and RNA, it consist of two subunits; the smaller one is involved in placing messenger RNA to bind and the bigger subunit involved in amino acid inclusion.

Hence, the correct option is (C). Lysosomes.

Note:The students may get confused that ribosome also show polymorphism as it have two subunit one work for messenger RNA and one for amino acid but we should clear that polymorphism means many forms of a single entity which is only observed in lysosomes.
