Flowers: are the reproductive apparatus of flowering plants (angiosperms). This image shows a generalised structure of an imaginary plant. The most obvious parts of a flower are the petals, shown here in brilliant pink. These are often colourful and can attract insects to help in pollination. Pollen is shown leaving the anthers at upper left and pollen is shown landing on the stigma at top middle.
STEM: the flower is supported on a stem
RECEPTACLE: the swollen top of stem that bears the flower structures
SEPALS: lower whorl of modified leaves (often green as in this image)
PETALS: upper whorl of modified leaves (often brightly coloured in this image)
STAMENS: male part
FILAMENT: long, thin supporting structure (shown as very pale green)
ANTHER: source of pollen (shown as brown elongate structures with yellow dots)
PISTIL: female part
OVULE: contains the egg cell and accessory cells
OVARY: swollen lower part of pistil
STYLE: elongate middle part of pistil
STIGMA: upper swollen part of pistil (pollen lands here)
In some flowers, the sepals and petals are almost identical (e.g. lily).
