ACKNOWLEDGEMENT

First and foremost, I  would want to praise Allah  for


providing me with the strength and blessing that allow me

to complete this work. I  might not have gotten this far
without His blessing.   With my devotion and responsibility,
I  always strive hard to finish this lesson book
development assignment.

I would want to express my gratitude to my lecturer,
Madam Fairuz Binti Mohd Dalim because my assignment
could not be completed successfully without her guidance.
she always gives me encouragement and guidance on how
to do this assignment in order to get a positive outcome.
She was a huge inspiration for me to work on this project. I

would also like to express my gratitude to her for
instructing me . Last but not least, I would like to thank
University Technology Mara (UiTM) campus, Puncak Alam,

History Corner In 1665,an English scientist named Robert Hooke
invented a simple microscope to observe a piece of
cork.He saw lots of small box-shaped structures within
the cork.Therefore,he named the structures as cells.
In 1674,Antonie van Leeuwenhoek invented a powerful
microscope .He observed moving microorganisms in a
drop of rain water using his microscope.

Systems in the human body

There are various systems that carry out important functions inside human body. Each
system consist of a few organs that work together to carry out a specific function. The
various functions of all systems must be coordinated so that the human body can carry out
all life processes or activities effectively.

Homeostasis in living things
At the end of the lesson

Homeostasis in human ,students should be able to :

Homeostasis refers to the maintenance of the internal


environment in the body of an organism 3.1.1.Communicate details

about homeostasis.

3.1.4.Appreciate the

importance of homeostasis in

correctly

Figure 9.Homeostasis control process.

When the internal environment in our body such as the body temperature
increases,the control centre at the brain will detect the changes .A corrective
mechanism will then take place and the temperature will reduce to its normal
range.When the body temperature decreases,a corrective mechanism will take
place and the temperature will rise to its normal range.

The condition of skin layer during higher and lower surrounding temperature:

Higher surrounding temperature



Sweat glands produce more sweat to cool the skin when sweat is evaporated.
Hairs lie flat to reduce air trapped on the skin so that heat can be released easily.
Blood vessels dilate to let more blood flow close to the skin to increase heat loss

Lower surrounding temperature



Erect hairs trap a layer
of air that acts as a heat insulator.
Blood vessels constrict to let more blood flow away from the skin to reduce heat

loss.

Homeostasis in plants Transpiration helps plants to absorb and carry water

Water from plants are lost through a

process known as transpiration. plants.Evaporation of water from the leaves cools the

plant during hot days.

What is Guard cells control the opening and closing of stoma.During the

stoma? day,stoma opens to enable exchange of gas.At the same time,water

vapour will be lost from the leaves and this will increase the rate of


water intake by the roots.
