Similarities: animal hormones and plant hormones are very small in the body, and they can also regulate physiological activities and development; For example, auxin regulates plant growth and development, and growth hormone regulates animal growth and development.
Difference Between Plant Hormones and Animal Hormones:
1. Production site: plant hormones do not have special secretion organs, and are produced by a certain part of the plant body; Animal hormones are secreted by specialized endocrine glands, such as the thyroid gland, pancreatic islets, gonads, etc.
2. Site of action: plant hormones do not act on specific organs; Animal hormones are secreted into the bloodstream and circulate throughout the body with the blood, acting on target organs and cells.
-
Similarities: 1. They are all transported from the production site to the action site to play a role; 2. They all have the characteristics of trace and high efficiency: 1. The chemical nature is different; 2. Animal hormones are secreted by endocrine glands or endocrine cells, plants do not have endocrine glands, and plant hormones are secreted by specific organs.

Answer: Plant hormones are substances produced by plants that have a significant regulatory effect on plant growth, development and metabolism. Animal hormones refer to chemicals that regulate and transmit information produced by the body's secretory cells and endocrine glands in higher animals and humans.
Plant hormones and animal hormones are two completely different types of substances. First of all, their composition is very different. The chemical composition of animal hormones is more complex, and some of them are steroid compounds, such as male hormones, estrogen, adrenocortical hormones, etc.; Some are proteins, such as pituitary hormones, insulin, thyroid hormones, etc.; There are also unsaturated fatty acids, such as prostaglandins.
Plant hormones, on the other hand, have a simple composition and a relatively small molecular weight. Secondly, the mechanism of action of the two is completely different. Although they are all active substances in the organism and need to be combined with receptors (target cells) through hormones to cause cell physiological responses, there are only target cells of plant hormones in plants, and only target cells of animal hormones in animals, therefore, plant hormones cannot produce physiological and biochemical reactions similar to their physiology and biochemical reactions in plants after entering the human body, and they cannot play any regulatory role in the human body.

The two are too different, each has its own role, and they are not universal. Plant hormones include aurisin, auxin, abscisic acid, etc., and animal hormones include estrogen, male hormones, progesterone, etc.

Animal hormones are secreted by specialized endocrine glands, such as the thyroid gland, pancreatic islets, gonads, etc.

Animal hormones are secreted into the bloodstream and circulate throughout the body with the blood, acting on target organs and cells.
-
Plant hormones are produced by plant cells and can be transported from the site of production to the site of action, while animal hormones are secreted by endocrine organs or cells and transported through body fluids.
-
Plant hormones are produced by various parts of the plant body, and animal hormones are secreted by specialized endocrine organs or cells.
Animal hormones are transported through body fluids, while plant hormones are transported in a variety of ways, of course, there must be no body fluids, such as auxin can be transported polarly.

It is a chemical signal that animals attract the opposite sex.
Except for mammals, the rest of the animals are basically oviparous, such as birds, snakes, crocandiles, turtles, lizards, frogs, salamanders, fish, insects, ......Among the mammals, platypus and echidna also lay eggs.
1. Frogs: Frogs have four toes on their front feet, five toes on their hind feet, and webbed, green on their backs and white on their abdomen. Frogs have big eyes and look very intrigued, and when they want to hunt, they will stick out their long tongues and drag insects and other pests directly into their mouths to eat. >>>More

The gray magpie, also known as the mountain magpie, is an expert in preying on pine caterpillars, known as the "forest guardian", it is said that a gray magpie can eat more than 15,000 pine caterpillars and other pests a year. >>>More
The five most intelligent animals are pigs, octopuses, crows, dolphins, and elephants.
The great white shark, also known as the man-eating shark, is the largest carnivorous fish, with a length of up to meters, a weight of 3,200 kilograms, and a tooth length of 10 centimeters. But precisely because of its particularly large size, it can be considered to be the ultimate predator of the food chain, that is, the highest consumer. Many crocodile movies are based on great white sharks, and the bloody scenes also make great white sharks' terrifying attack power deeply rooted in people's hearts.
