    *Monocots exhibit fibrous root system whereas Dicots exhibit taproot system.
    *Leaves in monocots show parallel venation whereas leaves in dicots show reticulated venation.
    *Monocot flowers possess petals in the multiples of three whereas Dicot flowers possess petals in multiples of four or five.
    *Monocots do not show any secondary growth whereas Dicots sometime exhibit secondary growth.

    The greenhouse effect is how heat is retained by the atmosphere due to greenhouse gases whereas global warming is the increase in average annual temperatures across the globe.
    The sun emits heat and light and some of that heat is trapped in the atmosphere by greenhouse gases.
    The greenhouse effect occurs naturally. Lately the greenhouse effect has been magnified due to greenhouse gases emitted into the atmosphere by humans.

    Global warming refers to the increase in annual average temperatures across the globe. As the amount of greenhouse gases in the atmosphere increases, the planet becomes warmer and warmer on average.
    Global warming is happening due to the greenhouse effect combined with increased greenhouse gas emissions by human activities.
