What are the similarities and differences between plants, animals and humans?

Similarities:
First, plants, animals, and humans are all made up of cells; all of these organisms are eukaryotes. They still consist of organic substances: proteins, fats, carbohydrates.
Humans and mammals have similar organs and general structure. For example, all mammals have 7 cervical vertebrae, a diaphragm.
For many animals, as well as for humans, sexual reproduction is characteristic, at a time when the plant can reproduce vegetatively.

Differences:
In a plant cell there are special organelles – plastids. They are not in the animal cage. Plants are autotrophs and producers, while animals and humans are heterotrophs, consumers and decomposers.
Humans have more resemblances to mammals, so when I mean the differences between animals and humans, I will be referring to orders before mammals. For humans, live birth is characteristic, in contrast, for example, to fish, which spawn. The main difference between man and plants and animals is that man has adapted to live in a social environment, he is able to think and perform purposeful labor activity.
