What is seed dispersal?
Q: What is seed dispersal?
A: Seed dispersal is the way seeds get away from the parent plant to a new place. It involves spreading or scattering the seeds in order for them to take root in other places and not compete with each other or the parent plant.
Q: How did plants disperse their spores and seeds before flowering plants appeared?
A: Before flowering plants appeared, virtually all transport of spores and seeds was done by mechanical means such as wind or water.
Q: What type of relationship do flowers and insects have?
A: Flowers and insects have a co-evolutionary relationship, where they rely on each other for pollination and fertilisation.
Q: When did this mutualism between hymenopterans (bees) and angiosperms (flowering plants) begin?
A: The mutualism between hymenopterans (bees) and angiosperms (flowering plants) began in the Upper Cretaceous period when nectar started appearing in flowers.
Q: How are spores dispersed?
A: Spores are almost always dispersed by wind.
Q: How are fruits adapted for dispersal?
A: Fruits are adapted for dispersal by animals, so they need to be nutritious and good to eat in order to be eaten by animals who will then spread them elsewhere.
