Tulip's reproductive structures. The female part of the flower is the carpel,at the top of which is the stigma (white). This is supported on the style,at the base of which are the ovaries that contain ovules. Surrounding this are the male stamens anther (brown) which contains pollen grains (the male sex cells of the plant). Fertilisation takes place when pollen lands on the stigma and grows down the styles to the ovaries where the fertilisation of the ovules takes place | |
