Question

multiple choice question
what is the network, usually made of polysaccharides, that surrounds many bacteria and some fungi?

capsule

pili

chitin

peptidoglycan

Explanation:

• Pili are hair-like structures for bacterial attachment, not a polysaccharide surrounding layer.
• Chitin is a polysaccharide but forms fungal cell walls, not a surrounding network for both bacteria and fungi.
• Peptidoglycan is the bacterial cell wall component, not a polysaccharide layer for fungi.
• Capsules are polysaccharide-based networks that surround many bacteria and some fungi, matching the question's description.

Answer:

A. Capsule
