The sun is the primary source of energy for living things mostly organisms like plants and ecosystems. But if you're talking about the bonds inside organic molecules, which are carbohydrates. With this, the energy from the sun gets trapped within a chemical bond and still relates to photosynthesis in plants.
mitochondria and chloroplasts, which have their own DNA and membranes, suggests that these organelles descended from prokaryotes that were engulfed by a larger cell.

Answer:
Pressure is constant & W= PV
Explanation:
If you lookat this picture.You can see that temperature is changed...that means internal energy is changed.And you can see pressure is 2atm always...
and also because the volume is incresed we can calculate the work using
W=p∆v
W=2atm*1m^3
So that equation is also true for this system.
Well, while it is true that the plant cell wall is rigid it's more important that it stretches. That's how it protects.
