A newly discovered prokaryote is found to have a dense, well-defined outer layer composed of polysaccharides, similar to the capsule shown in Figure 27.4. Based on the provided text, which of the following is NOT a likely function of this layer?

  • A: Enable adherence to their substrate or other individuals.
  • B: Protect against dehydration.
  • C: Conduct photosynthesis for energy production.
  • D: Shield pathogenic prokaryotes from attacks by their host's immune system.

Explanation

The text describes the functions of the capsule as adherence, protection against dehydration, and shielding from the host's immune system. There is no mention of photosynthesis or energy production related to the capsule. Photosynthesis is a distinct metabolic process not performed by the capsule itself.
