Q3:
How did Robert Hooke contribute to the development of cell theory?
- AHooke studied plant tissues and determined that plants are composed of cells.

- DHooke determined that all living organisms are composed of cells.
- EHooke used a microscope to view a piece of cork that he determined was made up of small compartments he called “cells.”
Q4:
How did Antonie van Leeuwenhoek contribute to the development of cell theory?

Q7:
Which of the following best defines cell theory?

- BIt is the scientific theory that states that all cells are genetically and structurally identical across all living organisms.
- CIt is the scientific theory that states that all living animals are made up of groups of differently specialized cells.
- DIt is the scientific theory that states that cells are the basic unit of life and make up all living organisms.
