- plant reproduction
- parts of flower
- sepals- protects the flower
- petals- brightly coloured to attract insects
- stamen - male part of the flower
- anther- produces male sex cells ( pollen grains)
- filament-holds up the anther
- nectary-creates nectar which attracts insects
- female part of the plant (carpels)
- stigma- collects pollen grains ( male sex cells )
- sticky
- ovules- contains the ovary
- ovary-produces female sex cells
- stigma- collects pollen grains ( male sex cells )
- fertilisation
- pollen grows pollen tube to ovule
- nucleus of pollen goes through tube
- fertilizes the ovule nucleus to make a seed
- nucleus of pollen goes through tube
- fertilized ovule -embryo
- after the female parts become fruits
- the seeds
- embryo- young plant with shoot
- food store - provides food for developing plant
- seed coat- a protective covering
- pollen grows pollen tube to ovule
- pollination
- insects carry pollen
- attracted to nectar and bright petals
- winds carry's pollen
- lands on the stigma of another flower
- self polination
- insects carry pollen
- dispersal
- so baby seeds don't have to fight for resources
- the wind
- specifically shaped
- animals
- seeds are eaten and excreted elsewhere
- stick to animals fur
- self propelled- the pop open shooting away from plant
- parts of flower
