Question

Which characteristics are true for all cells?
SELECT ALL THAT APPLY
a maintain stable internal conditions
beableto grow and divide
c need energy
d
independent of their environment

Answer 1

Correct answers: a, b, and c.

- a (maintain stable internal conditions): true — cells regulate their internal environment (homeostasis).
- b (be able to grow and divide): generally true as a basic cell property (cells arise from pre‑existing cells and can grow/divide). Note: some highly specialized cells (e.g., many mature neurons, mammalian red blood cells) no longer divide, but growth/division is a fundamental cell capability.
- c (need energy): true — all cells require energy to carry out life processes.

- d (independent of their environment): false — cells depend on their environment for nutrients, signals, and waste removal.
