Which of these is a unicellular fungus?
Mushroom
Yeast
Mould
Amoeba
What is a unicellular organism?
An organism made up of many cells
An organism made up of a single cell
A plant that can photosynthesize
A virus that infects cells
Which of the following is an example of a multicellular organism?
Amoeba
Yeast
Human
Bacterium
How do unicellular organisms carry out life processes?
They have specialized cells like humans do
They rely on other organisms for survival
A single cell carries out all life functions
They do not carry out life processes
Why are multicellular organisms more complex than unicellular organisms?
They have only one cell
They have specialized cells that perform different functions
They do not need to obtain energy
They can survive without oxygen
Which of these is NOT a characteristic of multicellular organisms?
They grow by increasing the number of cells
They have different types of cells with specific functions
They always reproduce asexually
They are made up of many cells
Which of the following is an advantage of being multicellular?
The organism can perform all life processes with one cell
The organism can have specialized cells for different functions
The organism does not need to obtain energy
The organism can survive extreme conditions without adaptations
How do fungi obtain nutrients?
By photosynthesis
By engulfing their food like amoeba
By absorbing nutrients from dead or living organisms
By producing their own food
What is the main structural component of fungal cell walls?
Cellulose
Chitin
Protein
Lipid
How do yeast cells reproduce?
Binary fission
Budding
Mitosis
Spore formation
Which type of fungi is responsible for causing athlete’s foot?
Yeast
Mould
Dermatophyte fungus
Protist
What is a key difference between fungi and plants?
Plants do not contain a nucleus
Fungi have chloroplasts, but plants do not
Fungi absorb nutrients from other organisms, while plants make their own food
Plants are unicellular, but fungi are always multicellular
What are protists?
A group of unicellular and simple multicellular organisms
A type of bacteria
A kind of fungus
A group of viruses
Which of the following is an example of a protist?
E. coli
Plasmodium
Salmonella
Yeast
Which protist causes malaria?
Plasmodium
Amoeba
Paramecium
Chlamydia
How do protists move?
Using flagella, cilia, or pseudopodia
Floating in water passively
Crawling like worms
They do not move at all
Which of these is NOT a characteristic of protists?
They can be unicellular or simple multicellular
They have a nucleus
They belong to the plant kingdom
Some can photosynthesize
How does Plasmodium spread from person to person?
Through direct contact
Through contaminated food
Through mosquito bites
Through the air
What type of cell are bacteria?
Eukaryotic
Prokaryotic
Multicellular
Fungal
How do bacteria reproduce?
Budding
Binary fission
Sporulation
Mitosis
Which of these diseases is caused by bacteria?
Influenza
Tuberculosis
Malaria
Athlete’s foot
What is a pathogen?
Any kind of microorganism
A microorganism that causes disease
A harmless type of fungus
A type of cell in the human body
What is an antibiotic used for?
To kill viruses
To kill bacterial infections
To kill protists
To increase bacterial growth
Why don’t antibiotics work on viruses?
Viruses do not have a cell wall
Viruses are larger than bacteria
Viruses are the same as fungi
Antibiotics can only treat fungi
What is the purpose of culturing bacteria in a lab?
To increase the spread of infection
To study bacterial growth and characteristics
To make antibiotics
To kill bacteria
Which of these is the best condition for bacterial growth?
Cold temperatures and low nutrients
Warm temperatures and nutrients
Dry environments with no nutrients
Freezing temperatures and no oxygen
What is used to grow bacteria in a lab?
Nutrient agar
Distilled water
Sand
Vinegar
Why must aseptic techniques be used when culturing bacteria?
To encourage bacterial growth
To avoid contamination
To make the bacteria grow faster
To stop the bacteria from reproducing
Which method is commonly used to sterilize equipment before culturing bacteria?
Boiling in water
Using an autoclave
Washing with soap and water
Freezing
Why should petri dishes be incubated at 25°C in schools rather than at higher temperatures?
To kill bacteria faster
To prevent the growth of harmful pathogens
To encourage more bacterial growth
To keep the petri dishes clean
