If light is imagined as a flow of particles, the particles are called photons with each photon carrying a discrete packet of energy. ..
1) a) Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
Hydrolysis is equals to hydro which means water plus lysis which means splitting. Therefore, hydrolysis means splitting/breaking a chemical bond by the addition of water (H2O). More accurately, it is by the introduction of the elements that make up water which are hydrogen and oxygen. Simple example of hydrolysis reaction is an ester is hydrolyzed into an alcohol and a carboxylic acid. Condensation on the other hand is the opposite of hydrolysis. Condensation occurs when two Hydrogen and one Oxygen are LOST from a compound or compounds during the reaction. Most often this occurs when 2 reactants form one product were bond between them being formed by the concerted loss of water (H2O). Condensation example is an alcohol + a carboxylic acid -> ester + H2O.
