Question

1. match: read about each organelle. then match each organelle to its function/description.

_____ capsule
_____ nucleoid
_____ plasmid
_____ flagellum
_____ pilus
a. hair - like structure that the cell uses for movement.
b. hair - like structure that attaches the cell to a surface and can transfer genetic material from one cell to another.
c. region inside a cell that contains genetic material but is not surrounded by a nuclear membrane.
d. outermost layer of the cell that provides protection.
e. circular piece of genetic material.

1. compare: what structures are present in a bacterial cell, but not in a plant or animal cell?

Explanation:

1. Match based on bacterial organelle functions:

• Capsule: Outermost protective layer (D).
• Nucleoid: Unbound genetic region (C).
• Plasmid: Circular genetic material (E).
• Flagellum: Hair-like structure for movement (A).
• Pilus: Hair-like structure for attachment/genetic transfer (B).

1. Bacterial cells have unique structures not in plant/animal cells: capsule, nucleoid, plasmid, pilus (some bacteria have flagella, but plant/animal cells lack the others listed).

Answer:

2.
Capsule: D
Nucleoid: C
Plasmid: E
Flagellum: A
Pilus: B

1. Capsule, nucleoid, plasmid, pilus.
