Zachary flowers
Pollination
Within one flower
From one flower across to another flower
Happens before fertilisation
With the help of
Wind
Small
Dull coloured
Reproductive organs hanging outside the flower
Stigma
Feather like
Increase surface area
Increase the chances of catching pollen grains
-Insects -Butterflies -Birds -Bees
Sticky / Spiky pollen grains
Nectar
Large petals
Scented flowers
Colourful
Petals
After fertilisation
Petals of the flowers drop off and wither
Colourful
Insect pollinated
Dull
Wind pollinated
Male parts
Anther
Produces pollen grains
Reproductive cell
Filament
Female parts
Ovary
Produces ovule
Egg cell
Seed
Fruit
Style
Stigma
Receive pollen grain
Grows a tube down to the ovule
Fertilisation only happens after the pollen grains fuse with the ovule
Sticky
Fertilisation
Fusion of male and female sex cell
Pollen grain
Lands on stigma
Produces pollen tube
Grows down the style to reach the ovule in the ovary
Ovule
Seeds
Germination
Conditions needed
Warmth
Air
Oxygen
Water
True leaves appear third
It can make its own food
Only at this point the seedling needs sunlight to go through photosynthesis
Roots appear first
Will always grow towards the ground
The roots know where the ground is because of gravity
Shoots appear second
Seed leaves
Provides the seeds with nutrients
It shrinks as the seed leaves develops
Shrivel and drops of when the plant is able to photosynthesise
Seed coat
Protects the seed from
Weather
Digestive juices
Seed dispersal
Animals
