The human activities directly or indirectly affect the nature. The deforestation and the removal of the vegetation for the purpose of development or timber, the land is exposed to the dangers of the landslide. The tress, plants and other vegetation keeps the soil in place with the help of their roots. The soil erosion is prevented by the trees, but the cutting down of them by the humans increases erosion and hence, the risk of landslide.
Animal cells:
They are self sufficient, because of Nano-Chemical factories, so they can make their own stuff like cell membranes.
A cell can destroy itself through apoptosis in the event that it is irreparable.
Plant cells:
These were the first type of cells discovered by us.
Plants only actually use about 1/6 of the energy they get from photosynthesis, the rest is stored for animals that eat the plant.<span />

Explanation:
Answer:
