Answer: When the plant has enough water in its cells the guard cells swell up and open the stomata. When the plant isn't getting enough water the guard cells can't swell and the stomata stay closed, so the plant doen's lose water. But if the stomata are closed photosynthesis can't happen and eventually the plant might starve.

Based on this diagram, the organism is classified based on some similarities. In the upper-division, the similarities should be more general in the lower division, the similarities will be more specific. It was mostly based on an organ, for example: vertebrate.
An organism with the same phylum could be put in a different order.
But the organism with the same order should have the same phylum and class too since the order is located below the phylum. Those similarities are tightly correlated with the evolutionary relationship.
Phospholipids have 2 faces or poles: one hydrophobic (the tails which "run away" from water) and one hydrophilic (the heads which "like" water).
This means that when in a double layer in a aqueous environment, the heads will face the water and the tails will face each other.
