b.cells
c.plant and bacterial cells, but not animal cells,
d.animal and plant cells, but not bacterial cells,

Answer 1

B. Cells

Step-by-step explanation:

The plasma membrane is one of the essential structural and functional components of all the cells. It maintains the cell's interior and regulates the entry and exit of substances into and out of the cells. Both prokaryotic and eukaryotic cells have a plasma membrane.

Plasma membrane forms the outer most covering of an animal cell. Plant cells and bacterial cells have a cell wall outside the plasma membrane. Irrespective of the cell type, the plasma membrane is made up of a bilayer of phospholipids with a hydrophobic core. Several proteins are embedded in the lipid bilayer.
