Question 114

Why is it an advantage to a plant that its seeds are carried away from the place where they were made?

  1. So the seeds can find fresh soil that holds more food for the seedlings to live on
  2. So the seeds are warmed enough by the open ground to be able to germinate
  3. So the seedlings do not compete with the parent for light, water and spaceCorrect answer
  4. So the seeds can then be pollinated by a different plant of the same kind

Explanation

A seed that germinates directly beneath its parent grows in the parent's shade and draws on the same patch of soil water, so both plants do worse than they would apart, and distance removes that overlap. Searching for food in the soil is no reason at all, because soil holds water and dissolved ions while the plant makes its own food as soon as its leaves open.
