Plants provide most of world food and oxygen


Plants do not move and are called green plants and these include conifers and other gymnosperms, flowering plants, ferns, liverworts, mosses and green algae. They do not fall under the red and brown algae. In fact, it is believed that there are about 300.000 species, most of which around 260.000 to 290.000 plants seeds. Green plants provide most of the world of molecular oxygen. Ones that produce cereals, vegetables and fruits are staple foods of mankind.

Some in it’s great variety were used for medicine and as a garnish. Green ones have cell walls of cellulose and most of it’s energy derived from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophyll A and B, which gives them their green color. For instance, some are parasitic and have lost their ability to produce normal amounts of chlorophyll and photosynthesis. They are also characterized by sexual reproduction. Non-sexual reproduction is also common and by modular and indeterminate growth and change of generations.

 

Many species of Plants used for human consumption

There are many species of Plants, 2000 species used for human consumption. Many are rich in nutritional value. People are consuming most of them with seeds, nutrients contain fats such as omega. It is a healthy food with a high amount of unsaturated fat. Edible seeds are cereals, legumes and oilseeds. Some seeds can not be eaten, such as large seeds in the apple and cherries, which contain cyanide, or lemon in which it occurs choking.

They use light to convert inorganic molecules to proteins, carbohydrates, fats and other biomolecules containing reduced carbon in the form of carbon-hydrogen bonds. Water and carbon dioxide in photosynthesis converts solar energy into chemical energy in the form of simple sugars such as glucose, with separation of molecular oxygen. These sugars are used as a material for the production of plant growth and other biomolecules.
