Question
Statement I: Cells are the functional unit of life.
Statement II: All Cells are totipotent.Solution
Statement I is correct as cells are the fundamental and functional units of life, forming the structural and functional basis of all organisms. Statement II is incorrect because not all cells are totipotent. Totipotency refers specifically to the ability of certain cells (like zygotes and some plant cells) to differentiate into an entire organism. Information Booster:
- Totipotency is found in zygotes and some plant cells.
- Animal cells lose totipotency after early development.
- Stem cells exhibit pluripotency but not totipotency.
- Unicellular organisms perform all life functions within one cell.
