The cells are very similar in structure, the only cell remotely different are plant cells.
The nucleus is the brains of the cell, it tells every part of the cell what to do. You can compare it to the human brain.
The plant cell is smaller than the animal cell
I think you need to rephrase your question. A human cell IS an animal cell. Humans are animals. And yes, nuclei are found within animal cells, human are otherwise.
Because a human is an animal!
its bigger :(
No, an animal cell doesn't have a cell wall at all.
there are many parts to a cell as there are many rooms to a castle.
The cell membrane in an animal cell can be compared to human skin, as it serves as a protective barrier that regulates the movement of substances in and out of the cell, similar to how the skin protects the body and controls the passage of molecules.
an animal cell is basically the same of that of a human cell. There is no difference, only in how their reproduction system is...
Human and animal cells have the same basic structures, yet human cells usually have different jobs pertaining only to that particular cell.
The skin
It appears in a human cell, a animal cell and a plant cell.
