bloom develop to help plants reproduce themselves . It ’s relaxing to watch bees and butterflies move from plant life to plant , gathering pollen and nectar , but the bodily process is a sort of " business human relationship . " To reproduce , plant need to spread out pollen to other blossom to create seeds . Some parts of flowers are indispensable to producing seeds ; other parts help protect the flower while it ’s developing , or they attract pollinators .
Step 1
Most blossom have both a stamen , which is the male flower part , and a pistil , the distaff flower part . The stamen consists of geminate anthers , which are pollen sacs , on filaments . Filaments are long , thin stalks sitting in the middle of flowers that hold anther up in the air , making the pollen useable to wind and other pollinator . The yellow , gold or brownish powder on anthers is pollen , or manful reproductive cells . Each plant has several stamens . Pollen sacs resign their pollen onto the exterior of the anthers , which insects brush up against when they move around in flowers . The pollen that cohere to their bodies is distributed when they confab other flowers .
Step 2
Pistil
The pistil , a efflorescence ’s distaff part , is a tube that ’s often mould like a bowling pin and located in the very center of the flush . It extends further out than do the anther , which skirt it . A pistil has three role : a stigma , elan and ovary . The stigma is the sticky surface at the top of the pistil , to which pollen adheres from pollinators ' bodies . The tube - like structure that holds up the brand is the style , which leads down to the ovary . The ovary contains female testis cells , forebode ovules . If an egg is fertilise — this happens when pollen reach it — the ovule explicate into a seed .
Ovary and Ovule
During the process of fertilization , pollen acres on the stigma , and when germinated it mould a pollen underground that grows down the style and enters the ovary . Most plants contain at least several ovules . ( Reference 3 ) Male procreative cells , or sperm cell , travel down the underground and bring together with the ovule , fertilizing it . The fertilized ovule becomes the seed , and the ovary swells and becomes the yield , contain the seeds .
