Robert Hooke discovered_____________?
Correct answer: C. Cell
- A. Nucleus
- B. Mitochondria
- C. Cell
- D. DNA
Explanation
Robert Hooke examined a thin slice of cork in 1665 and observed many small box-like compartments, which he called cells. He did not discover the nucleus, mitochondria, or DNA, although these structures were identified later by other scientists. The most likely mistake is choosing the nucleus because it is a prominent cell structure.

About Animal and Plant Cell
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.
