Seeds are dispersed away from the parent plant so that when they germinate they don't compete for resources. Give 2 resources plants compete for
Light
Water
mineral ions - NOT NUTRIENTS!
What name is given to the transfer of pollen from the anther to the stigma of the same flower, or to another flower of the same plant?
Self pollination
What name is given to the transfer of pollen from the anther of one plant onto the stigma of a different plant?
cross pollination
Give three requirements for a seed to germinate
water
warmth
oxygen
What is the food store inside a seed made up of?
Starch
What enzyme is used to break down the food store inside the seed to produce glucose that can be used in respiration (to release energy for growth)?
Amylase
Why does a seed need oxygen in order to germinate
For Respiration
(to release the energy in glucose so it can grow)
Why does a seed need water to germinate?
It activates the amylase enzyme
(to break down the starch into glucose so that respiration can begin)
What chemical reaction will a plant start to do once it has grown leaves
Photosynthesis
