A solar cell has a similar function to a leaf.
the cell is a phospholipid bilayer. this means that there are 2 layers of phospholipids with hydrophobic tails and hydrophilic heads.
A good item for a cell membrane would be a thin plastic or cardboard

A cell membrane consists of two layers of phospholipids, making it a double-layered structure. This double layer is known as a lipid bilayer.
there are 2 layers. one for each side. like a sandwich and the layers are the bread. there are two of them so they can hold together the inside :]
Cnidaria are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick.
