One main difference between prokaryotic and eukaryotic cells is the presence of a nucleus. Prokaryotic cells lack a nucleus, while eukaryotic cells contain a nucleus.

An example of a prokaryotic organism is bacteria.

An organelle is a structure within the cytoplasm that performs a specific job in the cell. Three examples are mitochondria, vacuoles, and ribosomes.

The nucleus is a structure in the cytoplasm surrounded by a membrane (the nuclear membrane) and contains DNA. Inside the nucleus, you can find genetic material (DNA) and sometimes nucleolus, which is involved in the production of ribosomes.

Answer:

1) Prokaryotic cells are usually smaller, do not contain a nucleus, and are usually found in single-celled organisms. Eukaryotic cells are larger, contain a nucleus, and are normally found in multicellular organisms.

2)Bacteria

3) Mitochondria, vacuoles, ribosomes

4)The nucleus is the "brain-like" organ of a Eukaryote. It coordinates simple functions around the cell, and also contains DNA information and is involved with RNA synthesis and DNA replication.
