Organelles protect a cell by
A) sequestering biochemicals that could dismantle other cellular structures.
B) forming a thick outer barrier.
C) containing powerful enzymes that kill any bacteria that enter.
D) placing flag-like molecules on a cell's surface identifying that cell as belonging to a particular person.
E) producing new DNA if the genetic material is damaged.

Question

Quizplus · Accepted Answer

Organelles, such as lysosomes, can sequester harmful biochemicals and degrade them safely to protect other cellular structures from damage or destruction.

Answer: B is incorrect because organelles do not form the outer barrier of a cell.

Answer: C is partially incorrect because not all organelles contain powerful enzymes that kill bacteria. Some, like mitochondria, are involved in energy production.

Answer: D is incorrect because flag-like molecules on a cell's surface are not organelles, but rather cell surface markers.

Answer: E is incorrect because organelles are not capable of producing new DNA. DNA replication occurs in the nucleus, which is also an organelle.
