Flowering plants (angiosperms) are the most diverse plants on Earth, they come in all colours and shapes. The reason for their successful variations is the structure which contain their reproductive organs- the flower. Typically flowers have four organs, sepals, petals, stamens, and one or more pistils.
(Stamen)Male Reproductive Organs:
Anther: 4 pollen sacs in 2 pairs. Pollen is produced and stored here.
Filament: tube stalk that supports the anther and is attached to the base of the flower.
(Pistil) Female Reproductive Organs:
Stigma: region of flower that serves as a receptacle. The "sticky lip" captures pollen grains.
Style: slender tube that supports the stigma.
Ovary
Ovule
Sepals surround and protect the flower bud. Petals are usually colourful structures that attract pollinators.
Anther: 4 pollen sacs in 2 pairs. Pollen is produced and stored here.
Filament: tube stalk that supports the anther and is attached to the base of the flower.
(Pistil) Female Reproductive Organs:
Stigma: region of flower that serves as a receptacle. The "sticky lip" captures pollen grains.
Style: slender tube that supports the stigma.

Sepals surround and protect the flower bud. Petals are usually colourful structures that attract pollinators.
Flowers can be categorized as perfect (contains both male and female parts) or imperfect (contains either male or female parts).
