Why is it not a good idea for all seeds to grow directly under the parent plant?

The process of seeds spreading out from their starting place (parent plant) Distance from the parent plant is required so plants do not compete for resources Seeds have adapted to create different seed dispersal strategies and mechanisms SEED DISPERSAL

Some plants produce thousands of seeds to increase chances of dispersal and survival SEED NUMBERS

Usually very light Have adaptations such a sail, tuft, puffball, or parachute to catch the wind Seeds travel until the wind stops, they catch on something, or are soaked by rain or dew WIND

Usually grow in or near water and float to new locations Light weight and usually found inside a fruit with a waxy coating WATER

Some seeds stick to animals as they pass by and later fall off May have hooks or burrs or be sticky to attach to animals Animals eat fruit and drop or later eliminate the seeds ANIMALS/HUMANS

Parent plant propels the seeds through the air Some plants can propel their seeds up to 20 m EJECTION

Some plants use a combination of these techniques to increase the survival chances of the seed COMBINATION
