Angiosperms are a group of flowering plants that represent a major community in the plant kingdom. Angiosperms occur in all typical habits and constitute a very useful group of plants for animals and human beings. Characteristics include flowers, endosperm within the seeds, and the production of fruits that contain the seeds. They are classified into 2 different classifications, monocots and dicots. Monocots have a single seed per embryo, they have parallel veins, flowers that occur in 3's or 6's, and they have ''scattered" vascular tissue. Dicots have two seeds per embryo, they have netted veins, have a ''ringed'' vascular system, and have flowers in 5's or 4's.
Advantages
Having a flower vs a cone has a series of advantages. The bright flower attracts pollinators as well as its nectar does. They also have a specific target for pollinat
Life Span
Flowering plants are also classified by how long they live. Annual flowering pants live up to for only 1 year. Biennial plants live up to 2 years. Lastly, there are perennials, these flowering plants live up to for many years.

Life Cycle
The life of a flower starts with a seed. The seed grows into a germinating flower then a mature flower. Once it is a mature flower, it is ready to reproduce. It develops a flower, this allows fertilization and pollination. Pollination is the process of the pollen moving from the anther to the stigma. In the pollen that came from the anther (the male part of flowers) they contain half the DNA for the future flower embryo. These gametes move to the ovule where they combine with the female gametes. After fertilisation, a combined cell grows into an embryo within a seed formed by the ovule. Seeds are what a plant uses to spread new plants into new places. Each seed contains a tiny plant called an embryo, which has root, stem and leaf parts ready to grow into a new plant when conditions are right. Another part grows into fruit. Different flowers go through the life cycle in different amounts of time. Annuals do it in one year and Biennials do it in two. Perennials, however, take many years.
Animals and Angiosperms
Animals are a very necessary part of the reproduction of angiosperms. When an animal eats a fruit like a strawberry or an apple they eat the seed as well. They then poop out the seed somewhere else and the scat provides a fertilizer type of help and allows a new tree or bush. As for flowers, they need pollinators like hummingbirds and bees to transfer pollen from one flower to another.
