CREDITS
I would like to thank to parents, siblings and friends For
having helped me to complete this folio on time. To my biology
subject teacher. I would like to say a million Thanks for giving
me the assignment because through this assignment has
nurtured my passion to do more in -depth research on
hypertonicity
Introduction
Pickling is the process of preserving or extending the shelf life of
food by either anaerobic fermentation in brine or immersion in
vinegar. The pickling procedure typically affects the food's texture
and flavor.Pickling was used as a way to preserve food for out-of-
season use and for long journeys, especially by sea.
Objective
To understand and appreciate the importance of
movement of substances cross the plasma
membrane in daily life
APPARATUS
1. Container
2. Knife
3. Peeler
4. Cutting Board
MATERIALS
1. Mango
2. Vinegar
3. Salt
4. Water
Step 1 PROCEDURE
1. Prepared mango, vinegar, salt
and water
Step 2
2. Peeled the mango skin and cut
into long pieces and put in a
container
Peel and cut the
mango carefully
Step 3
3. Dissolve the salt in water and
place in a container that has the
mango that has been cut
Step 4
4. Put 65ml of vinegar into the
container
Step 5
5. Shake the container to make
sure the ingredients are mixed
well
Do not shake too
hard as it may spill
Step 6
6. Leave for 3 days and record
your observation
RESULT
Day 1 Day 2 Day 3
Base on the observation, the changes of pickles by every day is the colour
from clear to cloudy and the size is become smaller
DISCUSSION
1. State the process that takes place for pickling fruit/ vegetable. (1 mark)
Osmosis
2. Explain the process in question 1. (2 marks)
It’s a net movement of water molecules from an area of high water to an area of low water potential.
3. What is the function of salt and sugar in the making of pickle? (2 marks)
To make a hypertonic solution.
4. What happens to the fruit/vegetables after soaking in salt/sugar solution? (1 mark).
The size of fruit become smaller and the colour changes
DISCUSSION
5. Suggest a way to revive the turgidity of the pickles. (1 mark LOT’s)
Soak the pickles in the distilled water.
6. Give one advantage of pickling fruit/vegetables. (1 mark LOT’s)
The fruit will be prevent bad bacteria from growing .
7. Apart from salt and sugar, name another ingredient used for the pickling process and explain why the
ingredient is used. (3 marks) HOT’s
Vinegar, because the vinegar's acetic acid will increase the the vegetables' acidity and kill off any existing
microorganisms, which will help prevent prevent short-term spoilage.
DISCUSSION
8. Pineapple pickle is prepared by soaking slices of pineapple in a concentrated sugar solution. State two advantages
and disadvantages of this method compared with keeping fresh pineapple. (3 marks)
Among its advantages is that it can prevent or treat allergies and reduce the risk of some types of cancer, such as colon
cancer, but when using a lot of sugar to make oranges will certainly lead to diabetes and in addition will cause the
body to lack fiber.
9. A housewife uses excess sodium nitrate and phosphate fertilizer sprinkled on chilli plant and after 3 days, she
found out that the plant has withered and died.
i) Explain what happened to the chilli plant? (3marks)
The plant will wither because sodium nitrate and phosphate fertilizers are intended to fertilize the crop and are acidic
in nature. when a lot of acidic substances are added in excess will cause a hypertonic process that is the soil will
absorb all the water that is watered to the plants.
ii) Explain what should the housewife do before sowing on the ground to prevent the plant from withering. (3 marks)
Before sowing the plant, the housewife should include sodium nitrate and phosphate fertilizer once a week in small
amounts and water daily.
CONCLUSION
In our daily life, there is a movement of substances
across the plasma membrane in daily life.The
process of making a pickles, hypertonic solution is
formed.
