C, the lipid tails, are hydrophobic and repel water.
During the process of photosynthesis<span>, plants use energy from the Sun to convert carbon dioxide and water into glucose and oxygen. </span>These products<span> are, in turn, used by the plant or animals that eat the plant during cellular respiration to produce ATP. So it would be Carbon dioxide. Hope this helps. :)</span>
