BIOLOGY, M5 EQ-Bank 1 MC

A strawberry plant will send out over the ground runners which will take root and grow a new plant as shown.
 

This method of growing a new plant is an example of

  1. budding.
  2. binary fission.
  3. external fertilisation.
  4. asexual reproduction.

  • Runners are plant stems which grow and take root to produce a new plant.
  • This does not involve the use of pollen or seeds (sexual reproduction) and the new strawberry plant will be genetically identical to the first.

By Elimination

  • Budding in fungi, binary fission in bacteria and runners in plants are all examples of asexual reproduction (Eliminate A, B and C).
  • Frog spawning requires a female to lay eggs and a male frog to fertilise them with sperm.
