What are the structures and functions of prokaryotic cells, including details about the cell envelope, ribosomes, and inclusion bodies?
Understand the Problem
The question is asking for an in-depth exploration of the structure and function of prokaryotic cells, including their differences from eukaryotic cells, various components such as the cell envelope, ribosomes, and inclusion bodies, as well as how these structures contribute to the cell's characteristics and capabilities.
Answer
Prokaryotic cells have a cell envelope, 70S ribosomes, and inclusion bodies.
Prokaryotic cells are simple organisms without a true nucleus or membrane-bound organelles. They have a cell envelope protecting the cell, 70S ribosomes for protein synthesis, and inclusion bodies for storing nutrients. The cell envelope includes a cell wall, cell membrane, and sometimes an outer capsule.

Prokaryotic cells are simple organisms without a true nucleus or membrane-bound organelles. They have a cell envelope protecting the cell, 70S ribosomes for protein synthesis, and inclusion bodies for storing nutrients. The cell envelope includes a cell wall, cell membrane, and sometimes an outer capsule.
More Information
The cell envelope is crucial for protecting the cell and interacting with the environment. Ribosomes in prokaryotes are smaller (70S) compared to eukaryotes (80S). Inclusion bodies act as storage sites within the cytoplasm, helping cells survive in fluctuating environments.
Tips
A common mistake is confusing prokaryotic ribosomes (70S) with those in eukaryotes (80S). Also, it's important to remember that prokaryotic cells lack the compartmentalization seen in eukaryotic cells.
