Cell membrane of bacterial cell invaginates producing structure called:
Correct answer: C. Mesosome
- A. Polysome
- B. Endosome
- C. Mesosome
- D. Centrosome
Explanation
Mesosome is a convoluted membranous structure formed in a prokaryotic cell by the invagination of the plasma membrane. Polysomes are aggregates of numerous ribosomes that are in the process of actively translating mRNA into protein. Endosomes are membrane-bound vesicles, formed via a complex family of processes collectively known as endocytosis, and found in the cytoplasm of virtually every animal cell. The correct answer is, therefore, C.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.

Jameel identifies Gram-positive and Gram-negative bacteria by using the Gram staining technique. After the completion of the whole procedure, he observed under the microscope that the Gram-positive bacteria were stained purple (violet) and Gram-negative bacteria were red (pink) in colour.The reason for this difference in staining is that the cell wall of Gram-positive bacteria contains a layer that retains in staining.This layer is composed the purple crystal violet stain
