1. All living things are made of them
2. Using his microscope, he was able to see things smaller than those things that can be seen with the naked eye
3. All cells come from other cells, so the mold cells must have come from cells in the bread itself
4. By having long extensions, the nerve cell can send messages to other cells
5. The cell could not survive because there would be nothing to stop harmful substances from entering.
6. In the cytoplasm
7. The nucleus, because it is the organelle that determines which proteins are made

15. The plant would lose its structure and rigidity
16. Chloroplasts are needed for photosynthesis, and animal cells don’t have them.
