The life cycle of a dioecious flowering plant (angiosperm), the willow, has been outlined in some detail in an earlier section (A complex life cycle). The life cycle of a gymnosperm is similar. However, flowering plants have in addition a phenomenon called 'double fertilization'.
Angiosperm flower showing reproductive parts and life cycle. The characteristic feature of angiosperms is the flower. Its function is to ensure fertilization of the ovule and development of fruit containing seeds. [55] It may arise terminally on a shoot or from the axil of a leaf. [56]
Angiosperm life cycle. All multicellular plants have a life cycle comprising two generations or phases. The gametophyte phase has a single set of chromosomes (denoted 1n) and produces gametes (sperm and eggs). The sporophyte phase has paired chromosomes (denoted 2n) and produces spores.
The transition to flowering is one of the major phase changes that a plant makes during its life cycle. The transition must take place at a time that is favorable for fertilization and the formation of seeds, hence ensuring maximal reproductive success.
Angiosperm life cycle. The male reproductive organ of the flower, the stamen, produces pollen. The opening of anthers makes pollen available for subsequent pollination (transfer of pollen grains to the pistil, the female reproductive organ). Each pollen grain contains a vegetative cell, and a generative cell that divides to form two sperm cells.

Peas are an annual plant.. An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies.. Globally, 6% of all plant species and 15% of herbaceous plants (excluding trees and shrubs) are annua
