Question

Briefly describe these structures found in the interior prokaryotic cell:

- Internal membranes
- Nucleoid
- Plasmids
- Ribosomes

Answer 1

Prokaryotic cells contain internal membranes, a nucleoid, plasmids, and ribosomes.

Step-by-step explanation:

Prokaryotic cells have several structures in their interior:

1. Internal membranes: Prokaryotes lack membrane-bound organelles, but some have internal membranes called microcompartments. These microcompartments are tiny structures enclosed by proteins and contain enzymes involved in metabolic processes.
2. Nucleoid: Prokaryotes have a nucleoid region where the chromosomal DNA is concentrated. Unlike eukaryotes, prokaryotes lack a true nucleus.
3. Plasmids: Plasmids are small, circular pieces of DNA that may exist alongside the chromosomal DNA in prokaryotes. They can carry extra genetic information and provide advantages to the cell, such as antibiotic resistance or the ability to metabolize certain substances.
4. Ribosomes: Ribosomes are sites where proteins are made. They are present in both prokaryotic and eukaryotic cells.
