Identify an option that does NOT represent prokaryotic cells.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. Sperm.
A cell without a true nucleus or membrane-bound organelles is called a prokaryotic cell. All other forms of life, aside from those found in the kingdoms of Bacteria and Archaea, are founded on eukaryotic cells. The prokaryotic cells are represented by bacteria, blue-green algae, mycoplasma, and PPLO (Pleuro Pneumonia Like Organisms).
- Prokaryotic cells have only one cell which means they are unicellular.
- The cell membrane protects prokaryotes. With the aid of this membrane, they can develop a particular cytosolic environment conducive to biochemical reactions.
- These cells include ribosomes as well as free DNA. Despite being organelles, ribosomes are not sealed off by a plasma membrane.
- The DNA and ribosomes work in tandem to create the proteins that the cells require to gather nutrients, proliferate, and even protect themselves against external threats.
- Binary fission, which divides duplicated DNA into distinct cells, is the prokaryote's method of reproduction. For example-
- Escherichia coli.
- Streptococcus.
- Nostoc.
- Anabaena.
Additional Information-
Sperm-The seminiferous tubules in each testis are where the male reproductive system produces sperm. When the DNA from the egg and the sperm are united, a new person is born. The DNA is located in the sperm's head.
