Question

The jelly like substance present in the cell is called as
(A) Nucleoplasm
(B) Chromosome
(C) Chloroplast
(D) Cytoplasm

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.

Now lets us find the solution from the given options:
1. Nucleoplasm is composed of many substances like enzymes and nucleotides. These substances dissolved in Nucleoplasm.
2. Next, the chromosome is the thread-like structure of DNA molecules in a packed form. Chromosomes form the DNA tightly coiled around histone proteins to support its structure.
3. Chloroplast is the organelles found in plants, it is the site where photosynthesis takes place. It converts light energy into chemical energy.
4. Cytoplasm is enclosed by the cell membrane composed of thick solution and has jelly like structure. It consists of water, proteins, and salt.

Hence, the correct option is (D). Cytoplasm.

Note: Cytoplasm works as a buffer and also involves in the protection of the genetic materials of the cell. It even involves in the protection of cellular organelles from damage. And the most important function of cytoplasm is that it is the site for cellular respiration.
