Incorrect Statement Regarding the Structure of a Typical Bacterial Cell
The incorrect statement regarding the structure of a typical bacterial cell is option 'C', which states that bacterial cells possess well-developed membrane-bound cell organelles.
Explanation:
Bacterial Cell Structure:
Bacterial cells are prokaryotic cells, which means they lack a true nucleus and membrane-bound organelles. They have a relatively simple structure compared to eukaryotic cells. Let's discuss the correct statements mentioned in the other options and further explain why option 'C' is incorrect.
a) Cells possess naked circular DNA which is folded to form nucleoid:
- Bacterial cells contain a single, circular DNA molecule, also known as the bacterial chromosome. This DNA is not enclosed in a nuclear membrane and is freely scattered in the cytoplasm.
- The folded region of the bacterial chromosome is called the nucleoid. It is not a separate organelle but a region within the cytoplasm where the DNA is concentrated and folded.
b) Cells are surrounded by a peptidoglycan cell wall and a mucilaginous sheath:
- Bacterial cells have a cell wall that provides structural support and protection.
- The cell wall of most bacteria is composed of peptidoglycan, a unique polymer made up of sugars and amino acids.
- In addition to the cell wall, some bacteria may have an outer layer called a mucilaginous sheath or capsule, which can aid in attachment, protection, and evasion of the host immune system.
d) Ribosomes in these cells are 705 in nature:
- Ribosomes are cellular structures responsible for protein synthesis.
- Bacterial cells have smaller ribosomes compared to eukaryotic cells.
- The ribosomes in bacterial cells are referred to as 70S ribosomes, composed of a large 50S subunit and a small 30S subunit.
- These ribosomes are responsible for translating the genetic information encoded in the DNA into functional proteins.
c) Cells possess well-developed membrane-bound cell organelles:
- This statement is incorrect. Bacterial cells lack membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes, which are commonly found in eukaryotic cells.
- Bacteria have a simpler internal organization, with most cellular functions occurring in the cytoplasm.
Overall, option 'C' is the incorrect statement because bacterial cells lack well-developed membrane-bound cell organelles.
