Despite the opposite direction of the two central processes of the plant organism – photosynthesis and respiration and their localization in different cell organelles, there is a close relationship between them. First of all, for the flow of the breathing process, organic matter is needed to obtain energy. These substrates are primarily carbohydrates, which are formed in green plants during photosynthesis.
CO2 absorbed during photosynthesis is partially returned to the atmosphere due to respiration, and O2 released during photosynthesis is partially consumed during the same respiration.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
