Fruit farmers sometimes use a method called marcotting to reproduce newplants.

As shown in the diagram below, a portion ofthe branch of a parent plant is cutat the surface (stage 1).

Moist soil is wrapped around the area of the cut (stage 2).

After a few months, new roots will emerge from the cut area (stage 3).The branch with its new roots will then be removed from the parent plant andgrown on its own. stage 1stage 2 stage 3

roots

wrapped moist soil

magnified views of the stem

Which one of the following can be inferred from this reproduction method?

(1) (2)(3)

The new plant will not have the same characteristics as its parent plant. Fruit farmers have to use this method because there is no other way bywhich the plant can reproduce.

The new plant produces the same type of fruits since it inherited the genetic information from its parent plant.

(4)

The type ofthe fruit produced may not be the same as the parent plant as genetic information may not be passed on from parent to its young.

Based on your observation of the pod above, what can be inferred about plant K?

Plant K has large flowers. Plant K is a flowering plant. Plant K is a non-flowering plant.

(4)

Each flower of plant K has an ovary with one ovule only.
