Two types of cells that make up all living things on earth: prokaryotic and eukaryotic. Prokaryotic cells, like bacteria, have no 'nucleus', while eukaryotic cells, like those of the human body, do. So, a human cell is enclosed by a cell, or plasma, membrane. Enclosed by that membrane is the cytoplasm (with associated organelles) plus a nucleus.

A) Prokaryotic and eukaryotic cells
B) Animal and plant cells
C) Red blood cells and white blood cells
D) Neurons and muscle cells

Final answer:

Eukaryotic and prokaryotic cells are the two types of cells that make up all living things on Earth. Eukaryotic cells, such as those in the human body, have a nucleus that is enclosed by a membrane. Prokaryotic cells, like bacteria, do not have a nucleus.

Step-by-step explanation:

Eukaryotic and prokaryotic cells are the two types of cells that make up all living things on Earth. Eukaryotic cells, such as those in the human body, have a nucleus that is enclosed by a membrane. Prokaryotic cells, like bacteria, do not have a nucleus. Instead, their DNA floats around inside the cell.
