Plant cells are the only cells with chloroplasts
Flatworms absorb oxygen by diffusion mechanism through their
skin to the cells in their bodies. Since flatworms do not have a circulatory system,
their bodies' cells are positioned close to the skin to ease the uptake of
oxygen from surrounding fluids or water.

two, phospholipids, non polar, tails, polar, heads.
Explanation:
This is just basically illustrating one of the components of the lipid bilayer memebrane. The membrane is made up of two lipid layers with the polar head groups facing either the cytosol or the outer surroundings while the non polar tails facing each other. Such that this bilayer act as a barrier between the cytosol of the cell/organelle eg endoplasmic reticulum and the outer surroundings.
