Capsule is a structure present in prokaryotes but absent in eukaryotes.
<h3>What are prokaryotes? </h3>
Prokaryotes cells are cells that do not have structures bounded in a membrane. example include bacteria.
<h3>What are Eukaryotes?</h3>
Eukaryotes cells are organisms that have their nucleus and other organelles bounded in an enclosed membrane.
Prokayote e.g Some bacteria have capsules it is carbohydrates in nature and it enables the bacteria to attach themselves to the surface. This is not present in eukaryote cells.
Conclusively, Capsule is the structure present in prokaryotes but absent in eukaryotes.
