Question

task 1: fill in the blanks

1. the _ is the region where the bacteriums chromosomal dna is found.
2. prokaryotes are _ organisms meaning that they are single - celled.
3. binary fission is a form of _ reproduction.
4. the _ in bacteria create proteins.
5. the _ is a tail - like structure that helps the bacterium move.
6. the _ is a hair - like structure on the surface of a bacterium. it is used to connect to other bacteria for the purposes of conjugation.
7. _ are thread - like appendages that help a bacterium attach to other cells.
8. _ are pieces of dna that can contain genes which give bacteria some sort of beneficial advantage like antibiotic resistance.
9. _ is the term to describe a rod - shaped bacterium.
10. gram _ bacteria have cell walls made mostly of peptidoglycans. they are stained purple by gram staining.
11. bacterial _ involves a direct exchange of genetic material between bacteria.

Explanation:

1. In bacteria, the nucleoid is the area where chromosomal DNA is located.
2. Prokaryotes are unicellular organisms.
3. Binary fission is a form of asexual reproduction.
4. Ribosomes in bacteria are responsible for protein synthesis.
5. The flagellum is a tail - like structure for bacterial movement.
6. The pilus (or sex pilus) is a hair - like structure used in conjugation.
7. Fimbriae are thread - like appendages for attachment.
8. Plasmids are DNA pieces with beneficial genes (e.g., antibiotic resistance).
9. Bacillus is the term for a rod - shaped bacterium.
