7. Use the following information about an investigation to answer this question.
In an investigation, three pea seeds were placed in identical pots in three different locations in a
classroom. Each seedling germinated in the same amount and type of soil, and each received the
same amount of water for the duration of the study. At the end of the investigation, the heights and
leaf colours of the pea plants were recorded in the following data table.
Location
sunny windowsill
indirect sunlight
dark cupboard
Height (cm)
10
12
14
Leaf Colour
green
green
yellow
Which of the following hypotheses was tested in this investigation?
a. A pea plant needs water to grow.
b. A pea plant grown in the dark will not be green.
c. The more soil there is, the taller the pea plant will grow.
d. The height of a pea plant is dependent on the type of soil it is grown in.

SHORT ANSWER
8. ANS:
a) They must be able to conserve water. (1 Point)
b) Plants must have the following adaptations: (2 Points)
i) Spiny cacti have thick, fleshy stems to conserve water.
ii) Plants have waxy leaves to prevent water loss.
iii) Plants have spiny leaves rather than broad leaves to reduce the leaves’ surface area and to
decrease water evaporation.
iv) Plants have extensive roots to absorb water from their surroundings.
Animals must have the following adaptations:
v) Reptiles have scales to prevent water loss.
vi) Animals stay out of the heat during the day and come out at night to feed.
vii) Animals live in burrows.
