Plant Reproduction System
Female Parts
Stigma
Receive pollen grains
Style
Connects the stigma to the ovary & allows the pollen grains to grow down towards the ovary
Ovary
Protects the ovule and becomes the fruit after fertilisation occurs
Ovule
Becomes the seed after fertilisation occurs
Male Parts
Anther
Produces pollen grains and stores them in the pollen sacs
Filament
Holds up the anther
Fertilisation
fusion of the male and female reproductive cells
pollen grains falls on stigma and germinates, pollen tube grows out and through the style towards the ovule that contains an egg cell
Pollination
Transfer of pollen grains from the anther of one flower to the stigma of another flower or same flower
Methods of Pollination
Wind
non scented flowers
long filament
feathery stigma
small & light pollen grains
Insect & Animals
brightly coloured flowers
scented flowers
Short filament
Stigma is sticky and within the flower petals
Seed Disperal
Explosive action
Have fruit walls that spilt open with sudden force when ripe
Spilt open without sudden force
Water
fibrous husk to float on water
Wind
Light & small
Wing-like structure
Fine hair
Animals
Fleshy, brightly coloured & juicy fruits
Hard seed
Have hooks/stiff hair
