speeds up weed growth, therefore more energy is used for growth and less for reproduction. The plant therefore dies quickly without setting seed.

Question 2

used to produce unpollinated flowers, which increases plant yield and allows for seedless fruits

Question 3

giberellins used to increase fruit development

Answer 3

bigger fruits may be produced.
