~~10. a crisp head of romaine lettuce was purchased from a local grocery store. the customer who purchased the lettuce noticed that the store's produce was constantly sprayed with distilled (pure) water. once home, they noticed that the leaves of the lettuce no longer seemed as crisp and taut. using details learned about osmosis, explain why the lettuce was crisper at the store

The lettuce was crisper at the store because it was constantly sprayed with water. The distilled water, with which the the lettuce was sprayed passed through the semi permeable membrane of the plant and enter into the plant cells. This makes made the cells to be turgid and also made the plant to appear crisper. The lettuce looked less crisp at home because it was no longer sprayed with water and instead it is losing water from its cells to the environment.

Um can u take a picture of the work

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.
