Characteristics and classification of plants
The Kingdom of plants, vegetables or metaphytes includes eukaryotic living beings, without locomotive capacity, multicellular, with cells surrounded by a cell wall of cellulose, and with chloroplasts with which they carry out photosynthesis (autotrophic nutrition).
Plants arose about 500 million years ago from a group of aquatic protoctists resembling green algae. Although most plants live on land, the most primitive plants (mosses and ferns) still need water to reproduce. The rest of the plants, more evolved, have adapted to all environments because their cells form tissues and organs.
Botany is the science that deals with the study of plants.
Plants are autotrophs and, through photosynthesis, are capable of manufacturing organic matter from carbon dioxide, water and mineral salts.
