FAQs on Prokaryotic Cells Video Lecture - Biology Class 11 - NEET

1. What are prokaryotic cells?
Ans. Prokaryotic cells are a type of cells that lack a nucleus and other membrane-bound organelles. They are typically smaller in size and simpler in structure compared to eukaryotic cells. Prokaryotic cells include bacteria and archaea.
2. How do prokaryotic cells reproduce?
Ans. Prokaryotic cells reproduce through a process called binary fission. During binary fission, the cell's DNA replicates, and the two copies move to opposite ends of the cell. The cell then elongates and pinches off in the middle, resulting in two identical daughter cells.
3. What is the role of ribosomes in prokaryotic cells?
Ans. Ribosomes in prokaryotic cells are responsible for protein synthesis. They read the genetic information carried by mRNA molecules and use it to assemble amino acids into proteins. Prokaryotic cells have smaller ribosomes compared to eukaryotic cells.
4. How do prokaryotic cells obtain energy?
Ans. Prokaryotic cells obtain energy through various mechanisms. Some prokaryotes are autotrophs and can produce their own energy through photosynthesis or chemosynthesis. Others are heterotrophs and obtain energy by consuming organic matter or other organisms.
5. Can prokaryotic cells cause diseases in humans?
Ans. Yes, certain prokaryotic cells can cause diseases in humans. Examples include bacteria such as Escherichia coli, Salmonella, and Streptococcus. These bacteria have mechanisms to invade and harm human tissues, leading to various infections and diseases. However, not all prokaryotic cells are harmful, and many play crucial roles in maintaining our health and environment.
