Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.
On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.

Explanation:
Are those that become tornadoes, reaching the speed of 480km/hour and measuring up to 1500 mts in diameter in the soil, travel more than 100 km away.
For the answer to the question above,
Water absorbs vast amounts of energy. Likewise bodies of water release energy very slowly. Areas near water are usually milder. Organic materials (such as plants and animals) tend to absorb more energy. Unlike a desert that holds it. Thus air temp. in a forest is usually cooler than the temp. in a desert.
Since land and water heat at different temperatures, the effects of this process creates climates. For instance, warm weather and moisture from oceans can create hurricanes. I hope this helps
