Does any one know a lot about animal cells and their functions? I could use some help.

Animal cells are various sizes and different shapes and they cannot be seen with the naked eye. Parts of animal cells are: Cell membrane - forms the outer  covering of the cell.

Cytoplasm - gel like substance where all other cell organelles are suspended inside the cell.

Nucleus - contains the hereditary material DNA and directs the activity of the cell.

Centrioles -organise the microtubules assembly during cell division.

There are many more but I figure you don't need them as I don't really know much about them either.
