Why did plants develop organs and tissues during the transition from the aquatic environment to the development of the ground-air environment?
1) In an aquatic environment, each cell has access to all the substances it needs (CO2, H2O, phosphorus, etc.)
2) In the ground-air environment, co2 is in the atmosphere, and the rest of the substances are in the soil
3) Because of this, there is a need for specialized organs (leaves and roots) and tissues – conductive and mechanical
