Methane gas is more potent( roughly by 30 times), as a greenhouse gas than carbon dioxide. 
Explanation:
Greenhouse gases in the atmosphere trap infrared radiation (responsible for the transfer of heat) that reflects off of the earth's surface instead of allowing most of this radiation to escape to space. This causes heat to build up in the atmosphere. The more the greenhouse molecules are in the atmosphere the higher this effect is. Global warming is subsequently blamed for climate change around the world.

Answer:
The given cell represents an animal cell, in which the organelle labelled as 'G' is mitochondrion. Mitochondria are membrane-bound organelles and their inner membrane is folded inward to form finger-like structures or cristae.
The mitochondria are known as the powerhouse of the cells as they are site for biochemical reactions of respiration and energy production.
Thus, the correct answer is 'mitochondrion.'
