Lesson One and Two
Micro Organisms
There are three types of _________. None of these can be seen without the use
of the _______. A micro-organism or ________is a microscopic organism, which
may have a single cell or it may have many cells (multi-cellular). The study of
microorganisms is called___________.
There are many different types of microorganisms and they live in every part of
the _________ including soil, hot springs, on the _____ floor, high in the
atmosphere and deep inside rocks within the Earth's _____ .
Microbes are used by people in___________, both in traditional based industries
such as bread making and ________ production and in modern technologies
based on genetic engineering. However there are some ___________ causing
microbes which are harmful and can even cause death in _______ and animals.

Using your knowledge of the three micro-organisms; virus, fungi and bacteria
named the:
Smallest –
One that requires a host to reproduce –
One that does not have a nucleusOne that is added to bread during production-
Lesson 3
Read the following information on safety using microbes and answer the questions below
1. Treat all microorganisms as potential pathogens (potential killers!)
While the majority of microorganisms will not kill humans and have never been shown to
cause illness, under unusual circumstances a few microorganisms that are not normally
pathogenic can act as pathogens. Treat all microorganisms—especially unknown cultures—
as if they were pathogenic. A student who has a compromised immune system or has had a
recent extended illness should talk with his or her instructor before working in the
microbiology laboratory.
2. Sterilize equipment and materials.
All materials, media, tubes, plates, loops, needles, pipettes, and other items used for
culturing microorganisms should be sterilized. This prevents contamination of your
experiments by unknown micro organisms that may be on the equipment and by sterilizing
after use stops micro organisms growing after the experiment is finished.
3. Disinfect work areas before and after use.
Use a disinfectant, such as a 10% bleach or 70% ethanol solution, to wipe down benches
and work areas both before and after working with cultures. Also be aware of the possible
dangers of the disinfectant, as 70% ethanol can catch fire around open flame or high heat
sources. Bleach, if spilled, can ruin your clothing. Either alcohol or bleach can be dangerous
if splashed in the eyes. You should know where the nearest eyewash station and sink are
located.
4. Wash your hands.
Use a disinfectant soap to wash your hands before and after working with microorganisms.
Non-disinfectant soap will remove surface bacteria and can be used if disinfectant soap is not
available. Gloves may be worn as extra protection.
1. why is it important to use full health and safety precautions even when
working with known “safe” micro organisms?

2. Why is it important to sterilize all equipment before use in an experiment.

3. What potential hazard is there when using an ethanol based disinfectant
____________________________________________________________
4. What can be used if there is no disinfectant soap available.

Fungi, Virus, or bacteria
Disease
HIV
Cause
Leprosy
Athletes Foot
Cold
Small Pox
Flu
TB (tuberculosis)
Fungal meningitis
Bacterial meningitis
Complete the passage below
Although most micro organisms do not have any affect on our _______ a small
percentages do. The human body has developed defenses against micro
organisms to stop them firstly ___________ the body and then to fight them if
they do. The ___________ stops most of the micro organisms the body comes
into contact with from entering the body by presenting a _________ _________.
The openings of the body all have a defense to limit access to the body. The
________ and ________ pass into the stomach that has a type of acid which can
kill most micro organisms that it meets.
If a micro organism does get into the body the __________ __________ will
identify and destroy it. The main tool of the immune system are the _________
__________ cells which can digest the micro organism or can produce
____________ which are designed to attack and kill specific micro organisms.
The immune system can be strengthened by ________________. This is when
the body is intently infected by a ________________ or dead form of a disease
causing micro organism so that it can produce the correct antibodies to fight it in
the future.

Lesson 8
Statement
The cell membrane is responsible for
controlling the cell and contains DNA
DNA is wound in to structures called
chloroplasts
True/False Correction
DNA stands for deoxyribonucleic acid
Genes are found in sections of the
chromosomes and are passed on by one
of your parents
