Green Plants
2
4 Living Processes Movement- towards light Reproduction- fruits and seeds Nutrition- plants make their own food Growth- seedlings to bigger plants
3
What do plants need to grow well? http://www.bbc.co.uk/schools/scienceclips/ages/7_8/plants_ grow.shtml Sunlight Air Water Warmth Minerals
4
Germination Growing plant Flowering plant Pollination Fertilisation Dispersal of seeds
5
Germination Warmth Air Water Root downshoot upGrow leaves (to find light)(begin making food) When a seed starts to grow
6
Photosynthesis Carbon Dioxide and Light IN Food and Oxygen OUT Chlorophyll in LEAVES Making food using sunlight
7
Flowers Male part- STAMEN (Anther and filament) Female part- CARPEL (Stigma, style and ovary) Attract insects with their sticky nectar and bright colours
8
Pollination Two ways: Insect- pollen sticks to the insect and is transferred to the female part (stigma). Wind- pollen is blown onto the stigma. The transfer of pollen onto the stigma
9
Fertilisation Pollen (male sex cell) travels along the style to reach the carpel where the female eggs are stored. The fertilised egg becomes a seed. Joining of the pollen and the egg to make a seed.
10
Dispersal of Seeds 3 ways: By wind- dandelion seeds are blown away. By animals- they eat berries the seeds come out in the poo! By explosion- seed pods dry up then burst. Seeds are carried away from the parent plant to stop overcrowding
