Although some people are hypersensitized to pollen , the role pollen play in the life cycle of a plant life is nothing to sneeze at . florescence works , called angiosperms , produce pollen in a male flowered part name the stamen , comprised of a stem - like strand and pollen - shedding pod called the anther . In non - flowering plants , called gymnosperms , pollen is made in male - gendered cones .
Flower Parts
Flowering plant , or angiosperms , create structures to exchange genetic codes in the operation of making seeds . heyday are this specialized structure . Although flower may have both male and distaff flowered component , some plant species have flowers that are undivided - gendered , give birth manlike or female parts in separate blossom .
The female part of the peak is known as the pistil and is in the main found in the center of the peak . The pistil is make up of stigma , the style and the ovary .
The male part of the flower is be intimate as the stamen and usually surround the distaff pistil .
The Stamen
The single male floral part is referred to as the stamen , or androecium . A stamen is made up of a thin stem call a filum and pollen - replete pouch called an anther . Often each efflorescence has multiple stamen .
The Filament
The Anther
At the tip of the stamen ’s filaments is the anther , which is a single or ingathering of pollen sacs where pollen is produce , ripened and released . A pollen cereal is instant in size and is shaped unambiguously per each plant metal money .
Pollen
Each pollen metric grain is fill with male gametophytes of the plant . A gametophyte contains the genetic code , DNA , of the plant in one - one-half the amount . Once a pollen grain reaches and fertilize the ovary of the distaff flower part , the two one-half of the DNA code blend and make a viable seed that can later develop into a plant .
Cones
In non - flowering plant , called gymnosperms , no flowers are produced , but facts of life choose place via differently gendered cone . cycad and coniferous tree like pines and spruce are an example . Male cones are modest , slender , cylindrical structures that spilt open to throw copious amounts of pollen . Wind carries this pollen , distributing it upon nearby female cones and afterwards fertilizing ovaries in a right cone .
