1

Which of these is a unicellular fungus?

Mushroom

Yeast

Mould

Amoeba

1

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

1

Which of the following is an example of a multicellular organism?

Amoeba

Yeast

Human

Bacterium

1

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

1

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

1

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

1

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

1

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

1

What is the main structural component of fungal cell walls?

Cellulose

Chitin

Protein

Lipid

1

How do yeast cells reproduce?

Binary fission

Budding

Mitosis

Spore formation

1

Which type of fungi is responsible for causing athlete’s foot?

Yeast

Mould

Dermatophyte fungus

Protist

1

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

1

What are protists?

A group of unicellular and simple multicellular organisms

A type of bacteria

A kind of fungus

A group of viruses

1

Which of the following is an example of a protist?

E. coli

Plasmodium

Salmonella

Yeast

1

Which protist causes malaria?

Plasmodium

Amoeba

Paramecium

Chlamydia

1

How do protists move?

Using flagella, cilia, or pseudopodia

Floating in water passively

Crawling like worms

They do not move at all

1

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

1

How does Plasmodium spread from person to person?

Through direct contact

Through contaminated food

Through mosquito bites

Through the air

1

What type of cell are bacteria?

Eukaryotic

Prokaryotic

Multicellular

Fungal

1

How do bacteria reproduce?

Budding

Binary fission

Sporulation

Mitosis

1

Which of these diseases is caused by bacteria?

Influenza

Tuberculosis

Malaria

Athlete’s foot

1

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

1

What is an antibiotic used for?

To kill viruses

To kill bacterial infections

To kill protists

To increase bacterial growth

1

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

1

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

1

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

1

What is used to grow bacteria in a lab?

Nutrient agar

Distilled water

Sand

Vinegar

1

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

1

Which method is commonly used to sterilize equipment before culturing bacteria?

Boiling in water

Using an autoclave

Washing with soap and water

Freezing

1

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
