Segregation of alleles happens when the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. So if you had heterozygous tall plants and mated them (Tt x Tt), they would each separate into T and t, allowing each offspring to get either a T or a t from each parent. The possible genotypes would be TT, Tt and tt.

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.
