how (flowering plants)
seeds
adult plants produce flowers that are pollinated. then, the female reproductive cells in ovules are fertilised by the male reproductive cells in pollen grains. after fertilisation, the flowers will develop into fruits with seeds that are dispersed. the seeds will then germinate and grow into adult plants, repeating the reproduction process.
flower stuctures
both male and female parts on a single flower (e.g. hibiscus, tomato)
male and female parts on separate flowers (e.g. cucumber, maize)
male and female flowers on separate plants (e.g. asparagus, papaya

pollination
occurs when pollen grains are transferred from the anther of one flower to the stigma of the same flower or another flower of the same kind
insect pollination
flowers are usually very large, brightly coloured and scented

self pollination
does not depend on birds, insects or the wind

germination
-
a seed needs water, oxygen and warmth to germinate but does not need light
seeds do not need to germinate immediately after they are formed and can remain dormant until the conditions are favourable for growth
