Where does a Paramecium Live? - Correct Ans-Pond Water
What type of cell is a Paramecium? - Correct Ans-Eukaryotic Cell - Single cell organism
What does a cell do for itself? - Correct Ans-Find food, shelter, mate and reproduce,
escape from predators
What limits a paramecium? - Correct Ans-the number of biomolecular machines that it
can contain within itself
What technology is used to watch living cells? - Correct Ans-Bright field light microscopy
What does a paramecium use cilia for? - Correct Ans-feeding
Paramecium: The contractile/food vacuoles are a precursor to what? - Correct Ans-the
kidneys
What do the paramecium contractile/food vacuoles do? - Correct Ans-absorbs water
from the cytoplasm, gets bigger and spits out the water
Paramecium: What does the anal pore do? - Correct Ans-gets rid of undigested food
and/or particles
Paramecium: What does the gullet do? - Correct Ans-with an open mouth searches for
food
Paramecium: What is cilia? What does it do? - Correct Ans-Cilia are black lines that
move in a pattern across the organism in multiple rows. Moves the cell directionally.
(made up out of a type of cytoskeletal element called microtubules.
Technology: What is SEM? - Correct Ans-Scanning electron microscopy. Captured
digitally in shades of gray
What is psuedocolored SEM? - Correct Ans-Color is added to the gray scale SEM
What is the advantage of SEM? - Correct Ans-The resolution is much greater
What is the limitation of SEM? - Correct Ans-The cells need to be fixed, preserved in a
dead state.

What is a captured paramecium? - Correct Ans-captured by another organism and
being eaten
What is the paramecium's escape behavior? - Correct Ans-It sheds cilia to confused the
predator
Individual cells have limited_____________ - Correct Ans-number of bimolecular
machines
The whole can do more than________ - Correct Ans-the sum of the parts
When cells work together they behave in a social system called... - Correct Ans-a multi-
cellular organism
When a cell changes a function it changes...... - Correct Ans-its engineering
In a multicellular organism you have a division of.... - Correct Ans-labor
You are a multi-cellular organism - Correct Ans-True
What shape is a multicellular organism? - Correct Ans-different shapes
The shape of a cell is a reflection of..... - Correct Ans-its cell type
What cells can cause infections in our bodies? - Correct Ans-Prokaryotic cells
What cell evolved to destroy infecting cells? - Correct Ans-Macrophages
A macrophage is part of the ..... - Correct Ans-nonspecific immune system
Why is it important to know about the technology used in collecting data? - Correct Ans-
It is helpful to know when to use this technology and the pros/cons of using them
Why is it important to know about the limitations of the technology used? - Correct Ans-
It allows us to adapt, learn and grow in technology advancement
How is a sphere different than a circle? - Correct Ans-A circle is two-dimensional. A
sphere is 3d
Walking cell: Where is the nucleus? - Correct Ans-In the back of the cell
Walking cell: Where is the retraction fiber? - Correct Ans-In the back of the cell
Walking cell: What is the pancake, super-glue like plasma membrane? - Correct Ans-
Lamellipodia
