A virus that infects cells
Question 3
3.
Which of the following is an example of a multicellular organism?
Amoeba
Yeast
Human
Bacterium
Question 4
4.
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
Question 5
5.
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
Question 6
6.
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
Question 7
7.
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
Question 8
8.
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
Question 9
9.
What is the main structural component of fungal cell walls?
Cellulose
Chitin
Protein
Lipid
Question 10
10.
How do yeast cells reproduce?
Binary fission
Budding
Mitosis
Spore formation
Question 11
11.
Which type of fungi is responsible for causing athlete’s foot?
Yeast
Mould
Dermatophyte fungus
Protist
Question 12
12.
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
Question 13
13.
What are protists?
A group of unicellular and simple multicellular organisms
A type of bacteria
A kind of fungus
A group of viruses
Question 14
14.
Which of the following is an example of a protist?
E. coli
Plasmodium
Salmonella
Yeast
Question 15
15.
Which protist causes malaria?
Plasmodium
Amoeba
Paramecium
Chlamydia
Question 16
16.
How do protists move?
Using flagella, cilia, or pseudopodia
Floating in water passively
Crawling like worms
They do not move at all
Question 17
17.
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
Question 18
18.
How does Plasmodium spread from person to person?
Through direct contact
Through contaminated food
Through mosquito bites
Through the air
Question 19
19.
What type of cell are bacteria?
Eukaryotic
Prokaryotic
Multicellular
Fungal
Question 20
20.
How do bacteria reproduce?
Budding
Binary fission
Sporulation

Tuberculosis
Malaria
Athlete’s foot
Question 22
22.
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
Question 23
23.
What is an antibiotic used for?
To kill viruses
To kill bacterial infections
To kill protists
To increase bacterial growth
Question 24
24.
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
Question 25
25.
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
Question 26
26.
