Ions cannot directly cross the phospholipid bilayer which makes up the main part of a cell membrane. They cross the membrane through protein channels, pores or pumps.
There are many different protein channels. Some only allow one type of ion to move through, like a sodium channel, and others exchange ions (move ions in and out at the same time, like a potassium/hydrogen ion pump).
These are one of a type of cell connector called gap junctions.

Phospholipid head and protein
It helps the organelles float and stay in one place. Animal cells don't have a cytoplasm
A Cytoplasm
Cells Cytoplasm is found inside the plasma membranes of prokaryotic bacteria cells and eukaryotic animal cells. It is inside the cell membrane which is adjacent to the cell wall in eukaryotic plant cells.

Animal *cells* have cytoplasm (cyto = cell).
Phospholipid head and protein
No, cytoplasm is found in both plant and animal cells.
Cytoplasm is found in both animal and plant cells; The cytoplasm contains hereditary material, and chemicals in the cells
cytoplasm division occurs in animal cells when the cytoplasm cells have a cohesive reaction that overtakes the nucleas. When this happens the nucleas goes galactic and irritates the animal cell systems creating cytoplasm division which co-hers a distinctive change. Hope this helps :-) Professor Guilbert
