G1 is the cell growth phase where the cell accumulates nutrients and decide if it is going to undergo the cell cycle, as determined by the restriction point in G1. If the cell has insufficient nutrients or has not grown sufficiently to enter the cell cycle, it will remain in G1 or exit to G0 phase where it will not divide.
G2 occurs after S phase DNA replication in the cell cycle. In G2, the cell is growing and preparing for cell cycle by producing proteins required such as the centrosome.

Here's it! Good Luck!
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, after Mercury. Named after the Roman god of war, it is often referred to as the "Red Planet" because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth.
The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano, and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan.
