How do plants differ from animals?
In most cases, we easily distinguish the representative of the flora from the representative of the fauna. And we do it easily, not for a second thinking about how plants differ from animals. And purely intuitively we say that a cow is an animal, but a violet is a plant. But can you also easily figure out and answer where the corals, the tinder fungus, the viruses, the sponge-bodyaga should be taken? To plants or animals?
In most cases, the identification of an animal or a plant, due to the features characteristic of the representatives of these kingdoms of nature stored in our subconscious, occurs almost instantly. Let us try to formulate an answer to the question of how plants differ from animals.
The most important and most important difference between them, of course, is the ability to move independently, which is characteristic of animals. Plants are tied to the place of growth by their root system, and their movement can occur only under the influence of an external influence (a breath of wind, the “journey” of sea anemone on a hermit crab, etc.).Animals can move in search of food, sometimes for hundreds of kilometers.
Another, no less important difference between plants and animals is their way of feeding. Animals eat ready-made organic substances (herbivores eat plants, well, and predators catch game). Plants themselves synthesize organic matter through the phenomenon of photosynthesis and accumulate them. From the soil they get minerals and water. In nature, there are several types of plants that are called carnivorous. They feed on small insects, catching them, for example, with the help of sticky mucus or a sharp compression of flower petals in the bud. But their hunting is passive and, in the absence of game, they feed in the same way as all plants.
A different type of food causes a different type of structure of animals and plants. The animal organism is much more complicated. After all, they need to move in search of food, eat it, digest it, and all this requires energy. Therefore, animals appear different internal organs, designed to solve these problems. Plants for food is only enough to have leaves and roots.
Active movement requires high coordination of movement, which is impossible without the nervous system. The need to get their own food led to the formation of the senses.Plants are deprived of both the senses and the nervous system.
But in the microworld it is difficult to distinguish an animal from a plant, since there are many transitional forms. For example, scientists are still arguing, consider viruses as plants or animals.
