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

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.

Peter conducted an experiment to find out if the length of the
shadow of the pole depends on the time of the day. He placed a
wooden pole in the open on a sunny day. Next, he measured the
length of the shadow of the pole at every hour from 9 a.m. to 6
p.m.
Peter recorded his results in the following bar graph and showed
it to hisclassmates.
