Question Detail
Question
A cell must have 3 things: a. Plasma membrane, cytoplasm, nuclear membrane b. Plasma membrane, cytoplasm, DNA c. Cell wall, nucleus, cytoplasm d. Cell membrane, DNA & RNA
Correct Answer
Option B is the correct answer.
Detailed Explanation
To be considered a cell, an entity must have a plasma membrane to separate its interior from the environment, cytoplasm (the jelly-like substance where cellular processes occur), and genetic material (DNA) that directs its activities. A nucleus is not required for all cells (prokaryotes lack one), and RNA is not always a defining component.
Hint
Focus on the universal features: a boundary, an internal fluid, and genetic instructions.
