Explanation
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. It is the primary means by which energy from the sun is captured and transformed into chemical energy, which is then used by organisms for growth, development, and reproduction. During photosynthesis, chlorophyll in the plant's cells absorbs light energy, which is used to split water molecules and release oxygen as a byproduct. The remaining hydrogen from the water combines with carbon dioxide to produce glucose, which can be stored or used immediately for energy.

Explanation
DNA stands for deoxyribonucleic acid. This is the molecule that contains the genetic instructions for the development and functioning of all living organisms. It is composed of a long chain of nucleotides, each containing a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). The sequence of these bases in the DNA molecule determines the genetic code, which is responsible for the diversity and characteristics of different organisms. DNA is found in the nucleus of cells and is essential for processes such as replication, transcription, and protein synthesis.
