d) Aphids have been used to investigate the translocation of sucrose in phloem tissue. While they
are feeding on phloem sap aphids excrete a sucrose-rich fluid known as honeydew. In an
investigation, two groups of four aphids were placed at intervals along the stem of a young willow
plant, as shown in Fig. 3.2.
The leaves were enclosed in an airtight glass chamber. A special form of carbon dioxide gas that
contained radioactive carbon-14 (14C) was supplied to the leaves for a short period of time.
Samples of honeydew were collected at intervals from the groups of aphids. The time taken for
sucrose containing 14C to travel the distance between group A and group B was recorded. The
investigation was repeated twice using a fresh stem and different groups of aphids for each trial.
The results are shown in Table 3.1.

1. Emperor penguins are large birds found in Antarctica where temperatures can be very
low. Fairy penguins are small birds that live in Australasia where temperatures are
much warmer. The body temperature of both species of penguin is maintained at
approximately 38°C.
A student investigated the rate of heat loss from a penguin with a large body compared
with a penguin with a small body.
IGCSE/Class IX/Biology/2024-25
Page 1 of 13
They used a 250cm3 beaker to represent the emperor penguin and a large test-tube to
represent the fairy penguin.
The student used this method:
Step 1 Label the beaker A and the test-tube B.
Step 2 Draw a line on beaker A and test-tube B 5cm up from the bottom.
Step 3 Use hot water to fill beaker A up to the 5cm mark.
Step 4 Place a thermometer in the water in beaker A. When the reading on the
thermometer has stopped rising, measure the temperature of the water. Record this as the
starting temperature. Leave the thermometer in the water throughout the investigation.
Step 5 Start the stop-clock.
Step 6 After one minute, measure and record the temperature of the water in beaker A.
Step 7 Measure and record the temperature of the water in beaker A every minute for a
total of five minutes.
Step 8 Add hot water to test-tube B up to the 5cm mark.
Step 9 Repeat steps 4 to 7 using test-tube B instead of beaker A.

a) Cubes of agar jelly can be used as model cells. Agar jelly cubes are colourless and can
be stained pink with an indicator. When placed in an acid solution, the acid diffuses into
the agar jelly cubes and the pink colour starts to disappear. When the acid has reached
