The shared structures between nerve, bone, epithelial, and muscle cells is that they share reproduction structures and the same blood type.
Hemoglobin
The white blood cells.
Simple epithelial tissues have no blood vessels and line or cover structures.
Differentiation is the reason that there is a difference between a red blood cell and a white blood cell. Different cells carry different genes.
Red Blood Cells, White Blood Cells, and Platelets.
There are different types of cells, but the structures are basically same, with similar organelles and other structures.
Red blood cells
Not all cells demonstrate the presence of all intracellular structures because cells are specialized and have specific functions. Different cells require different intracellular structures to carry out their unique functions. For example, muscle cells have more mitochondria to generate energy for contraction, while red blood cells lack a nucleus to make more space for carrying oxygen.
Human and animal cells have the same basic structures, yet human cells usually have different jobs pertaining only to that particular cell.
Because every cell is different!
There are many different kinds of cells. The two overarching classifications are Prokaryotic cells (bacteria and other cells that lack a nucleus) and Eukaryotic (cells that do have a nucleus and a cell membrane). Eukaryotic can be further divided into categories such as plant and animal cells where there are more differences. Plant cells have a cell wall, chloroplasts and a large vacuole whereas animal cells only have small vacuoles. There is also cell differentiation in which cells have different structures to complement their different functions. Blood cells have different structures to nerve cells in humans, and liver cells contain massive amounts of ribosomes so they can create proteins.
