What is the difference between plants and animals?

Animals and plants are all organisms, but they are two completely different species, almost everyone can distinguish them.

But there are some varieties that are both animal and plant-based, such as coral that everyone is familiar with, more than 100 years ago, because it looks like roots, trunks, leaves. trees and branches should be mistaken for a plant.

So what are the main differences in animals and plants? Scientists embody the four aspects.

Almost all plants are germinated, resulting in the same result, it can be said that if not touch the root can live a lifetime. Of course, there are exceptions, such as small aquatic plants floating on water. In contrast to plants, the vast majority of animals seek food, avoid the enemy, or cause an unusual move, in the state of motion.

Plants from small to large, the organs still generate different changes and decreases, such as small periods with only roots, trunks, leaves. After the flower grows, then when the flowers withered away fruit.

The vast majority of animals (except low animals), regardless of whether they are small or large, organs such as the five corpses, the four limbs do not increase, not only the volume is not large. For example, lions or tigers that have just been born have had the same organs as their parents.

The habitat characteristics of the two plants are very important characteristics. In addition to a small number of parasites and spiders, they can all work in photosynthesis. They can produce "food" to feed themselves.

Animals can not do this, they can only rely on plant foods or other animal foods to feed themselves. The difference between plants and animals has a very clear standard.

Observing their cells under the microscope will detect that the plant's cells have a thick, medium-hard cell wall, but that the animal’s cell membrane only does not have a cell wall.
