What are the characteristics of each type of organism? Think about things like whether they have a nucleus, how many cells they have, and what cell structures they have. Give an example of an organism that fits in the category.

Answer 1

1. Prokaryotes (e.g. bacteria):
- Lack a nucleus
- Single-celled organisms
- No membrane-bound organelles
- Have a cell wall
Example: Escherichia coli (E. coli)

2. Eukaryotes (e.g. plants, animals, fungi, protists):
- Have a true nucleus
- Can be single-celled or multicellular organisms
- Have membrane-bound organelles
- Most have a cell wall (excluding animals)
Example: Saccharomyces cerevisiae (yeast)
