So big :)

My babies have gotten so big it makes me so happy :) But this is not as big as they will get! Eventually my babies will undergo reproduction. They will produce flowers which have petals, sepals, stamens,  carpels, and pollen. The sepals protect the floral bud before it opens and the petals attract insects and other pollinators to the plant with their color and fragrance. The stamen is the male reproductive organ of a flower. Each stamen generally has a stalk called the filament. At the top of the filament is the anther and pollen sacs.The center of this organism is where the reproductive process of pollination takes place. The carpel is the female reproductive organ of a flower. Each carpel has a stigma which is where pollen is deposited, the style which is the stalk between the stigma and ovary, and the ovary which holds the ovules for fertilization. The pollen fertilizes the ovule in the ovary and eventually develops into a seed. Then the seed will eventually fall to the ground and being the growth of another baby plant! Double fertilization is when two sperm fertilize one egg! One sperm will actually fertilize the egg that will develop into an embryo. The other sperm combines with the two polar nuclei located in the center and forms a triploid endosperm nucleus. The endosperm basically provides extra nutrient for the seed!
