Flower structure and fertilisation





Flowers are the organs of sexual reproduction in plants. They have the following important structures:





sepals - protect the unopened flower bud





petals - may be brightly coloured to attract insects





stamens - the male parts of the flower consisting of the anther held up on the filament





anthers - produce male sex cells (pollen grains).





stigma - the top of the female part of the flower which


collects pollen grains





ovary - produces the female sex cells (ovules)





nectaries - produce sugary nectar which attracts insects

Reply:As you left the work at school, I have given you a few websites to find out the stuff you need (I ignored ones like wiki as you should be able to find what you need somewhere else and other people in the class will use wiki! - and I think using wiki is too easy and therefore a little cheaty!





Good luck!
