The graph shows that since the early twentieth century, the concentration of CO2 in the air has increased to historic levels. Based on this timeline, which three of the following developments could explain this rapid deviation from expected temperatures?

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

b.have there own function.
