The female part
The carpel - consists of the stigma, style and ovary
Pollen

The egg
Is made in the ovary of the carpel
Reproduction involves 5 stages:
Pollination Fertilisation Seed and fruit formation Seed dispersal Germination
Pollination
Is the transfer of pollen from anther to stigma
Plants are pollinated by either
Insects or wind
Fertilisation
Is the fusion of the pollen nucleus with the egg nucleus to form a zygote
A seed
Is a fertilised ovule
The ovary wall
Becomes the fruit
Seeds are dispersed
To avoid competition
Seeds are dispersed by
Animal
Wind
Self-dispersal
Water
Germination
Is the growth of a seed into a new plant
Seed germination
Is necessary to form a new plant
A geranium
Can reproduce asexually by using leaf cuttings
Plants reproduce sexually
By means of flowers
