Question

Complete the following paragraph to describe the components of bacterial cells. Choices may be used more than once.

a. ribosomesb. capsulec. nucleusd. plasma membranee. plasmidsf. flagellag. nucleoidh. thylakoidsi. cell wall1. Prokaryotes are surrounded by a _______________ that regulates the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure and the __________, which increases the ability of pathogenic bacteria to cause disease.2. The DNA of a prokaryote is arranged in a single coiled chromosome located in the ___________.3. Some prokaryotes carry genes on extrachromosomal pieces of circular DNA called _________.4. Embedded within the cytoplasm are small organelles composed of RNA and protein called __________ that function in protein synthesis.5. Some prokaryotes, such as cyanobacteria, are photosynthetic and contain __________ to aid in photosynthesis.6. Some bacteria contain appendages such as __________ which are long whip-like structures to aid in locomotion, fimbriae, which are small bristle-like fibers to function in attachment, or conjugation pill, which are short tubular structures to aid in the exchange of genetic material.

Answer 1

Answer: 3.

Step-by-step explanation:

Answer 2

1d; 2b; 3g; 4e; 5a; 6f

Step-by-step explanation:

1d: cell membrane is found in both eukaryotes and prokaryotes . It is selectively permeable to molecules and regulates transport of material across the membrane.

2b: capsule forms the outermost layer of some bacteria and confers resistance to attack by the immune system.

3g: nucleoid contains the genome of bacteria and unlike the nucleus it is not surrounded by a membrane.

4e: plasmids occur naturally in bacterial cells as a means for antibiotic resistance and defense against toxins and other bacterial species.

5a: ribosomes are found in both eukaryotes and prokaryotes, although structurally different they act as a site for protein synthesis.

6f: flagella is primarily used for locomotion.
