Question

Chromonemata are embedded in
A. Stroma
B. Matrix
C. Sugar
D. Mucilage

Answer 1

Chromonemata is the aggregate of chromomere. It is defined as a thread of chromosome that remains uncoiled during the process of prophase and gets its spiral form at the time of metaphase.

Complete Answer:
Let’s discuss the options and find the correct answer.

Option A: Stroma, is defined as a colorless fluid which is present surrounding the grana in the organelle chloroplast. Grana is present within the stroma and from here photosynthesis begins. The chemical changes are commenced earlier in the stroma. Therefore, this is the incorrect option.

Option B: Matrix is the substance that is found in between the eukaryotic cells. The term extracellular matrix refers to the structure of connective tissue. It is a jelly-like substance found in the cytoplasm. In the matrix, Chromonemata is embedded. Therefore, this is the correct option.

Option C: Sugars are also called monosaccharides. They are the basic carbohydrate molecule. These are the structural component cells and serve as the source of energy. Table sugar or sometimes granulated sugar are referred to as sucrose, that is a disaccharide and is made of 2 monosaccharides molecules i.e. glucose and fructose. Therefore, this is the incorrect option.

Option D: Mucilage is a gel-like, thick, gluey substance that is produced by plants or by some microorganisms. These include protists and other microorganisms. It is a glycoprotein that is polar in structure and is an exopolysaccharide. Therefore, this is the incorrect option.

Thus, the correct option is B) Matrix.

Note: Chromonemata is a thread-like small structure which is made up of DNA and protein, found inside the nucleus of the cell. Chromonema is the part of the chromatid so you should learn the basic structure of chromosomes.
