Angiosperm is the scientific term for flowering plants.
There are believed to be well over 350,000 species of angiosperm and there is a huge diversity among the species’.
Angiosperms are a phylum which encompass over 400 families and 350,00 species of plant, all of which have similar characteristics.
Before the emergence of angiosperms, gymnosperms and ferns were the dominant groups of plants, but angiosperms quickly established themselves as the most successful group within the plant kingdom.
Gymnosperms evolved before flowers and were around in the time of dinosaurs. They produce seeds as well as tiny drops of high-energy liquid.
Ferns do not have flowers and have a more primitive form of reproduction that angiosperms and gymnosperms.
Flowers - angiosperms - make up over 90 percent of all plants on Earth and there are over 350,000 different species.

Ferns do not have flowers and have a more primitive form of reproduction that angiosperms and gymnosperms.
The cause of the huge diversity of flowers has often be attributed to the co-evolution with animals and plants which aided in reproduction.
Research from San Francisco State University has found that the stomata - cells which control gas exchange in plants - are much smaller in angiosperms than any other types of plants.
Angiosperms have more venation than other types of plants and this encourages greater rates of transpiration (water transfer), photosynthesis, and growth.
Flowering plants were the only type of plants that underwent rapid genome downsising during the early Cretaceous period which enabled the decrease in cell size.
