Tree of life

Plant Kingdom (Plantae)

Plants are an amazing kingdom of multicellular organisms possessing the unique ability to photosynthesize. By converting sunlight into organic matter, they have become the true foundation of life on our planet. It was plants that shaped the Earth's atmosphere by enriching it with oxygen, and to this day they sustain the vast majority of living beings.

From microscopic mosses to giant sequoias, Earth's flora amazes with its diversity and the perfection of its adaptation mechanisms. Botany is not just the science of stems and leaves; it is the study of the very foundation of the biosphere, understanding which is critically important for our common future and for preserving harmony on Earth.

Angiosperms

The most extensive and advanced group of plants, characterized by having flowers and fruits.

Gymnosperms

An ancient group of seed plants whose seeds develop exposed on the scales of cones.

Ferns

Elegant spore-bearing plants that flourished millions of years ago and have remained faithful to the forests.

Bryophytes

Tiny pioneers of the land, forming soft emerald carpets in the most diverse corners of the planet.

01

Today, science knows of more than 365 813 species of plants, and every year botanists discover about two thousand new taxa.

02

Plants produce about 90% of all oxygen on Earth, and the world's forests are a key regulator of our planet's climate.
