They require cells to use water.
- Photosynthesis uses water as a reactant (splitting H2O provides electrons and O2).
- Cellular respiration involves water (is produced in aerobic respiration and used in metabolic reactions).
Other choices are incorrect: neither process always requires oxygen (respiration can be anaerobic), neither always requires organelles (prokaryotes carry out both without organelles), and only photosynthesis requires sunlight.
