Requires 2 parents and any offspring will have properties of both, requires specialized sex cells, slow process.
Germination
The process of plant growth, doesn’t require any sunlight and stops once the plant has grown leaves and is able to photosynthesise

What do petals do?
Attract incects for pollination
Sepals
Protects the flower when it’s in bud
Anthers
Produces the pollin
Filaments
Supports the anthers
Stamen
The male part of the flower which consists of the anther and filament
Stigma
The female part of the plant that recieves the pollin
Carpels
The female part of the plant that consists of stigma, style and ovary
style
Supports the stigma and the part that the pollin tube grows down to to fertillise the egg
Ovary
