There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms. A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.</span>
Because cell wall of bacteria and fungi have different chemical composition
Plants need Chloroplasts, during photosynthesis they need Chloroplasts to proceed with photosynthesis
The mechanism in a cell's connected section of the membrane that detects chemical signals is i.e. structure labelled B in the diagram. Thus, the correct option is D.
<h3>
What are receptors?</h3>
Receptors, which are large proteins that can be found within or outside of cells, are the components of a cell that are in charge of identifying chemical signals.
Whereas plasma membrane junctions interact with surface proteins found inside cells during cell to cell signaling.
Thus, it follows that the structure designated B in the diagram is the one that serves as a chemical signal receptor.
