Yeast is used in making bread, how does yeast cause bread to rise?
Yeast is a fungus that digests sugar and produces gas, this, when trapped in dough, causes bread to rise when baked
100
True or false: When bacteria reproduce, they give birth to another bacteria
False, they don't give birth, they simply duplicate
100
What is the main difference between bacteria and archaea?
They are made of different materials
100
Which domain contains multicellular organisms?
Eukarya
100
Which species is most involved in what is widely considered Earth's sixth mass extinction?
Amphibians, being killed by fungi!
200
How do fungi reproduce
They use spores, which is a form of asexual reproduction. This is all FOSS wants you to know, but there are many fungi who are capable of and partake in both sexual and asexual reproduction
200
How quickly do bacteria reproduce?
Very quickly, the fastest taking only 5 minutes to duplicate
200
What is similar between archaea and bacteria?
They have all of the same cell structures, just made of different materials
200
Why did people not realize archaea and bacteria were different until the 1970's?
Archaea are a lot like bacteria, except they are made of different materials. Microscopes weren't powerful enough before then to see that.
200
How do deep sea vent bacteria move from vent to vent
We have no idea
300
What is unique about how fungal cells are grouped together?
There are holes in the cell walls connecting them, forming a tunnel.
300
Name 2 ways we have looked at in class that bacteria positively interact with humans
Some examples include:
Food digestion in the guts of multicellular organisms
Cheese and yogurt
Killing other bacteria
300
Do archaea have a nucleus? What does this make them?
No, they are prokaryotes
300
Bacteria and Archaea are similar because both are what
Both are prokaryotes. They technically both have a cell wall, but they are made of different materials
300
What is a bacterial cell wall made of? For an extra 500, what is the cell wall of archaea made of?
Peptidoglycan, a polysaccharide (its made of sugar)
Archaea have a cell wall made of glycoconjugates and polysaccharides
400
What is the job of fungi ecologically?
They are decomposers, they digest dead material
400
Do bacteria have a nucleus? What shape is their DNA in?
No, they have circular DNA
400
How closely related to bacteria are archaea?
Not closely at all. Archaea are as far away from bacteria as humans are
400
Name the three domains
Archaea, Bacteria, and Eukarya
400
Why do some describe American chocolate as "tasting like stomach acid"
Modern chocolate contains butyric acid, which is the signature taste component of stomach acid
500
True or false: A Fungal cell may have more than one nucleus
True, because there is nothing dividing the cells, they nuclei can move between them
500
How do bacteria acquire new genes and traits, despite how they duplicate?
Bacteria can transfer DNA between each other
(Fun Fact: This is called Horizontal Gene Transfer)
500
Which organisms, bacteria, archaea, or fungi, are most like tomato plants? Why?
Fungi. They are eukaryotes (the other two are prokaryotes) with the most similar cell structure.
