Question

List the features found in prokaryotes but not eukaryotes. What are advantages provided by these features?

The Flagellum, Capsule and Fimbriae are found in prokaryotes.

Answer 1

Answer : prokaryots lacks membrane bound organelles like mitochondria, nucleus etc.

Rigid cell wall: it is present in prokaryots which helps bacteria in pathogenesis and survival in extreme condition.

Nucleiod: As the DNA is in direct contact with cytoplasm so transcription and translation occurs simultaneously as compared to eukaryotes.

Plasmid: it is present in prokaryots but rare in eukaryotes. It contain some important genes.

Haploid genome: benefits includes- the mutation rate is low and allels are rapidly transfer.

1. Flagella : it is present in prokaryots. Most of the prokaryots are motile and flagella help in movement and pathogenesis.

2. Capsule: they protect bacteria from being phagocytosed by the host immune cell. Capsule also contain water content which prevent bacteria from being desiccated.

3. Fimbriae : fimbriae help in adhesion or attachments of bacteria so that the bacteria colonies itself and protected from detachment.

Pilus help in conjugation.
