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.
No we dont. us males have one less.
1. When there is increase in the temperature of the air soil temperature also increases and also the increase may become more intense when the water content in the soil is low. 2. When the air temperature decreases there will be general decrease in soil temperature too but this factor also depends on the height and depth of the soil
