Tricks of Animals and Plants What are the tricks of animals and plantsWrite about the tricks of four

1. Poaceous plants do not have any active defense capabilities and rely entirely on numbers to ensure their existence. Because they grow fast and reproduce vigorously, they are not susceptible to herbivore extinctions.

2. The "blood" of oleander and milkweed contains cardiac glycosides, and insects will die due to muscle relaxation after eating them.

3. Tobacco and water poison hemlock are not only poisonous, but also have an unpleasant smell, and some animals will not "come" again after the first visit.

4. Although plants such as dried yew and evergreen are non-toxic, they can produce ecdysone or similar substances, and insects will have developmental deformities after eating, such as molting early or unable to reproduce. The substances in the body of such plants protect themselves.

5. The thorns growing on the trunk and branches of the honey locust tree (leguminous) are a natural "protective film" for animals.

6. The spines of chestnuts grow on the total bracts, and animals dare not eat them. These plants use sharp needles, thorns, and thorns to keep their enemies away.

Cactus: has specialized leaf spines that reduce water evaporation and play a protective role.

Nepenthes: Has a specialized cage that can be used to catch insects.

Skunk: Releases a stench to drive away predators.

Analysis: When mimosa is attacked by locusts, it immediately rolls up its leaves and does not open them again until 20 minutes later.

In South America, there is an orchid called "Mai Beauty", which dances in the wind to "summon" swarms of bees.

A species of buffalo locust that grows in East Africa, the tree has long, sharp thorns on its body, which is beyond the reach of people.

The coconut tree allows its seeds to travel long distances, as the coconut shell contains enough nutrients and water to keep the seeds adrift at sea for months until they reach a new shore and take root.

In South Dakota, USA, there is a species of flytrap that wraps up the nectar when insects such as flies suck it up and secretes a digestive juice to kill the insects.

The fruit of the Hula tree contains a great poison that can cause blindness when a person's eyes touch it.

Seeds of some plants were found in a 2,000-year-old storage room in the tundra region of Germany, most of them were dead, but one seed sprouted and grew after watering, and later bloomed into beautiful magnolia flowers.

Chameleon's eyes.

The chameleon is a type of lizard. One of its eyes resembles two small pagodas, and the eyeballs are exactly there"Pagoda"Pointed, two"Pagoda"It can stretch and contract, it can also rotate at will, and even turn around, and it can really see in all directions. What's even more amazing is that the two eyes can go their own way and have nothing to do with each other.

Inspired by the chameleon's eyes, scientists invented a spherical camera, which stands on"Pagoda"On the tip, you can rotate it at will to shoot a 360-degree space, and the effect is excellent. There are also people who invented a chameleon eyepiece, which allows people to hide behind the wall, send the eyepiece out of the wall, and observe everything outside the wall, which is both concealed and safe, and is very popular with police and detectives.

Tiny fireflies.

The little firefly has long attracted the attention of many scientists. After a long period of exploration, the principle of its luminescence has been clarified. It turns out that its luminaire is composed of two substances, luciferin and luciferase.

This light does not generate heat and is called cold light. With the development of molecular biology, scientists are now working to isolate the luminescent genes of fireflies and implant them into flowers and trees through genetic engineering, so that they can fluoresce and sparkle everywhere. More importantly, fluorescence can be used to create luminous walls that do not radiate heat or luminous luminaries that produce cold light, which are extremely convenient for operating rooms or research laboratories, as well as for the army's work at night.

Analysis: Example 1: A plant --- curly cypress, when the conditions are harsh and drought, the roots shrink and pull out of the ground, and drift away with the wind. Wait until the conditions are right, take root and be reborn. What a wonderful emigration!

Example 2: There is a snake called the viper, and its venom can instantly coagulate blood. Naturally, there will be no good results after the prey is bitten.

Example 3: There is a jellyfish in Australia that has stinging cells on its tentacles that can penetrate the heart of the attacked person and kill a person in 180 seconds. Do you dare to touch this kind of thing?

Example 4: There is a flower that I don't remember what it was called. It prevents the bee that falls into it from flying out, and can only allow it to crawl through a narrow passage of the flower. By the way, take the pollen of the flower and force it to help pollinate. Clever enough, right?

Example 5: The cuckoo, a kind of slippery bird, can neither nest nor hatch eggs to feed its chicks, and when it comes to the reproductive season, it lays its eggs in the nests of many birds such as willow warblers, and the baby cuckoo instinctively squeezes people's eggs out of the nest at once, laying its unique foundation. Feeding your offspring through other people's nests is a must!

Example 6: When an eagle hunts a tortoise, it throws the tortoise from a height, and after the tortoise shell breaks, the eagle can have a good meal.

Example 7: A beautiful dead leaf butterfly will stand its wings behind it like a dead leaf when it is resting, to avoid the attack of natural predators.

There are countless powerful tricks, just to name a few

Animals: Dragonfly flight; Ultrasound du in bats

Wave; the sense of smell of a police dog; DAO memory of carrier pigeons; the "social" division of labor between bees and ants; Flies have ...... immunity

Plants: wonderful photosynthesis, which converts inorganic salts into organic sugars and starches; different ways in which different plants transmit their offspring (wind, water, animal); photophobic cell transfer of sunflower; Sensory cell transfer ...... of mimosa

Since animals and plants have their own special functions for human research and reference, the discipline of "biomimicry" was born.

Venus flytraps and pitcher plants hunt insects. Snakes use their tongues to identify, bats use sound waves to locate them, wolves hunt en masse, and so on.
