Prokaryotes
Are Prokaryotes Unicellular or Multicellular?
Unicellular
Examples of Eukaryotic organisms?
Plants, animals, fungi, algae, protozoa.
As you increase the magnification....
the Field of View (FOV) is reduced
Dead or alive?
Dead. By definition they are not living at all!
What is a symbiotic relationship?
A ecological relationship between two organisms that generally benefit from one another. Other ecological relationships are not so positive for example viruses and humans!
Are Bacteria and Archaea Prokaryotic or Eukaryotic?
Prokaryotic.
How did Eukaryotic Cells evolve?
Symbiotic relationships (Endosymbiosis) between prokaryotic organisms that morphed together to form Eukaryotic cells.
What is the FOV formula?
FOV = Field Number / Objective Magnification
Name a virus shape/structure? Hint: There are 4 main ones.
Helical, Polyhedral, Spherical, Complex
Name the ecological relationship between Viruses and Humans?
Parasitism
How does a Prokaryotic Cell differ from a Eukaryotic Cell?
Prokaryotes are very simple, with limited cell organelles. They even lack a Nucleus!
What is the smallest cell in the human body?
Sperm Cell
What is FOV?
Field of View
Do viruses have DNA? Do they need a host to survive?
Yes and Yes!
How does a Eukaryotic Cell differ from a Prokaryotic Cell?
Eukaryotic Cells are very complicated with lots and lots of cell organelles!
What is a Flagellum? What does it do?
Its a tail like organelle for prokaryotic cells to move around/swim.
When did Eukaryotic Cells evolve?
3 Billion Years Ago!
Field of View can be defined as the...
observable area in distance units
Why do all viruses require a host to 'live'?
They cannot replicate their own DNA as they lack the organelles to do this. Instead, they poach and adopt these organelles from their host. Parasites!
What is Endosymbiosis?
A symbiotic relationship where one organism lives inside of another.
How quick can bacteria muliply?
Every 4-20mins! Insane!
What is the largest eukaryotic cell in the world?
An Ostrich Egg!
Why is calculating FOV important in Biology?
Very helpful with gaining insight into densities and concentrations of solutions required to develop medicines or drugs, for example antibiotics, anti virals, vaccines, etc.
Did viruses evolve from prokaryotes or eukaryotes? Why/why not?
What are the main units of measurement used in Biology? Hint: there are many correct answers here.
Nanometers, Micrometers, Millimetres, Centimetres, Mols/Litre, MicroMols/Litre.
