Termites and Protists
Termites cannot digest wood on their own. Tiny protists in their intestines help. What do termites and protists have in common?
Both are eukaryotic
Which group is non-living and only reproduces in a host?
Viruses
Mushrooms belong to which kingdom?
Fungi
Which genus of bacteria causes shigellosis?
Shigella
What medicine kills bacteria?
Antibiotics
What is the role of protists in a termite’s gut?
They help digest wood and dead plants.
Why are viruses considered non-living?
They cannot reproduce without a host.
Mushrooms use spores for what?
Reproduction
How does shigellosis spread?
Through dirty hands, waste, or contaminated water.
How do bacteria share resistance genes?
Through conjugation.
What kind of relationship is it between termites and protists?
Mutualism (both benefit).
Viruses that attack bacteria are called?
Bacteriophages
What part of the mushroom releases spores?
The fruiting body.
How can people avoid catching shigellosis?
Wash hands frequently.
What happens during conjugation?
One bacterium passes resistance genes to another.
Protists have what kind of cells?
Eukaryotic cells
What happens when a virus attacks a cell?
It injects its genetic material and makes new viruses until the cell bursts.
How can mushroom species be identified using spores?
By making a spore print and checking color and pattern.
How do bacteria survive harsh conditions for a long time?
They form endospores.
Put the steps in order: 1) Mutation makes one resistant, 2) Connects to another, 3) Passes gene, 4) Second reproduces.
1 → 2 → 3 → 4
One difference between termites (animals) and protists?
Protists are single-celled, termites are multicellular.
Why is it wrong to call a virus a “bacteria eater”?
Viruses don’t eat bacteria; they take over the cell and replicate inside it.
Are fungi autotrophs or heterotrophs?
Heterotrophs (they absorb food from other sources).
How long can Shigella survive on a fly’s body?
Up to 24 days.
Why is antibiotic resistance a problem?
Makes infections harder to treat.
