ovary, ovule
ovule, pollen
ovule, ovary
pollen, ovary
Flower is the reproductive part of a plant. The female parts of the flower will create an ovule (unfertilised egg). The egg will remain in the ovary and waits to be fertilised. The male parts (in particular, the anther) will produce pollen, which contains the sperm needed to fertilise the egg. After fertilisation, the ovary develops into a fruit whereas the ovules develop a hard coat and gradually gets converted into seeds.
