seed dispersal Flashcards
1
Q
why is seed dispersal important
A
to move the seed away from the parent plant to avoid competition of resources such as water and light
2
Q
list the different ways of seed dispersal
A
1) wind
2) animals/transport
3) bursting
4) rolling
5) water
3
Q
how are seeds adapted for survival
A
1) low metabolic rate so survive during winter
2) Testa physically protects embryo
3) endosperm and cotyledon provide nutrients which last until seedling emerges and photosynthesises
4) inhibitors only allow germination at suitable times of the year
5) dispersed great distances so no competition with parent plant
