How does rising CO2 concentration and global temperature affect different aspects of plants growth.

Expert Solution

Carbondioxide and global temperature are key variables in plant growth development and function. The rising carbondioxide concentration and global temperature affects different aspects of plant growth.

Rising CO2 concentration causes,

- Increase in yield by increasing the rate of photosynthesis.

- As CO2 levels increase, the stomatal pores donot open as wide, rresulting in lower levels of transpiration by plants and thus increase Water Use Efficiency/ WUE.

- Increases biomass- plant dry weight

- Increased tolerance for low light levels

- produce more number of mesophyll cells and chloroplast.

- Increased leaf area, leaf area duration

- Reduce crop damage from insects and pathogenic insects.

- Accumulates non structural carbohydrates on plant parts.

The rising global temperature causes,

- photosynthesis is unaffected or increased slightly at high temperatures.

- Increased accumulation of foliar sucrose and decreased starch accumulation in mature leaves.

- cause stunting and death of plants

- Reduced metabolic activity when temperature rises above 40 degree celsius.

- Transpiration and respiration rises.

- Affect proteins and enzymes.
