FAQs on Prokaryotic Cell Video Lecture - Biology for Grade 11

1. What are prokaryotic cells?
Ans. Prokaryotic cells are cells that do not have a nucleus or any other membrane-bound organelles. They are typically smaller and simpler in structure than eukaryotic cells, and they include bacteria and archaea.
2. What are some of the key features of prokaryotic cells?
Ans. Prokaryotic cells are typically very small, and they lack a nucleus or any other membrane-bound organelles. They have a cell wall that helps to protect them, and they often have a flagellum or other structure that allows them to move. They also contain DNA, which is typically found in a circular shape and is located in the cytoplasm.
3. How does the structure of prokaryotic cells differ from that of eukaryotic cells?
Ans. Prokaryotic cells are much simpler in structure than eukaryotic cells. They do not have a nucleus or any other membrane-bound organelles, and their DNA is typically found in a circular shape in the cytoplasm. Eukaryotic cells, on the other hand, have a nucleus that contains their DNA, as well as a variety of other membrane-bound organelles that perform specific functions.
4. What are some of the functions of prokaryotic cells?
Ans. Prokaryotic cells are involved in a variety of important functions, including metabolism, reproduction, and movement. They are also involved in many processes that are important for the environment, such as the breakdown of organic matter and the cycling of nutrients.
5. How do prokaryotic cells reproduce?
Ans. Prokaryotic cells reproduce through a process called binary fission. In this process, the cell first duplicates its DNA and then divides into two identical daughter cells. This process allows prokaryotic cells to reproduce very quickly and efficiently, which is one of the reasons why they are so successful in a variety of environments.
