Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
Ferns are examples of spermatophytes which have stems growing side ways
The alleles BB for black hair and LL for long hair are part of that cat's genotype. Genotype is the genetic make up of a cell, and therefore it determines characteristics of an organisms (phenotype). It is the genotype that determines the the hereditary potentials and limitations of an individual from embryonic formation through adulthood.
Answer: Organisms ingest large molecules, like carbohydrates, proteins, and fats, and convert them into smaller molecules like carbon dioxide and water. This process is called cellular respiration, a form of catabolism, and makes energy available for the cell to use.
