Question

Describe how and why some plants store carbon dioxide (CO2) more efficiently than others. Include a detailed discussion of the relationship between deforestation and climate change.

Answer 1

Some plants are C4 plants , CAM plants and some are C3 plants. Out of these C4 plants are most efficient in fixing and storing Carbon. The CAM plants store CO2 in the form of malate during the night and perform photosynthesis during the day.

The C3 plants are least effiecient due to a phenomenon called Photorespiration taking place in them.

As the climate will change and CO2 conc. Will increase the C3 plants productivity will be increased as the current levels of CO2 are limiting for these plants. Eg. Tomato.

Many plants like larger plants also store higher amount of CO2 in form of carbon. This is because of their larger structures like long trees of gymnosperms , angiosperm dicots etc. These are large woody trees and form large masses.

Their deforestation of will lead to increase in the CO2 levels of environment and lead to more climate change in the form of global warming etc।
