What do we use to study cells?
Microscopes
How do I know if something is living or nonliving?
All living things have cells. If I see cells, I know I am looking at a living thing.
What does the word "uni" mean?
(BONUS +100): Give an example of another word that has "uni" in it!
uni = one
(BONUS): unicorn, universe, unicycle, unibrow, etc.
Why do we use microscopes to study cells?
A microscope allows us to see cells because they are too small to see with our naked (un-aided) eyes.
Cells are the "building blocks" or basic structural unit of...
Cells are the "building blocks" or basic structural unit of... ALL LIVING THINGS.
Look at the image below. Is this sample from a living or nonliving thing? (BONUS POINTS +200: How do you know it is living/nonliving?)
This sample is from a LIVING THING.
BONUS +200: I know it is living because I see cells. All living things have cells.
This is actually an image of plant cells!
What does the word "multi" mean?
(BONUS +100): Give an example of another word with "multi" in it
multi = multiple or many
(BONUS): multiverse, multiply, multicolor, etc.
Which sample is smaller:
Sample A, shown at 10x magnification
or sample B, shown at 150x magnification?
Sample B-- the larger the magnification, the more "zoomed in" we have to be to see this sample.
What is an organism?
Organism = LIVING THING
Is this sample, pictured below, living or nonliving?
(BONUS +200: How do you know it is living/nonliving?)
LIVING
(Bonus +200): All living things have cells. I see a cell, so I know it's a living thing.
This is actually an image of a bacteria!
Is this sample multicellular or unicellular?
(BONUS +200): How do you know?
MULTICELLULAR
(BONUS): I see multiple cells BONDED/STUCK TOGETHER and IN A REPEATING PATTERN
Look at the chart below. What instrument will I have to use to study a plant cell?
light microscope
True or False: Nonliving things can be made of cells.
FALSE! Only living things are made of cells. They are the basic unit/building block of living things.
Is this sample from a living or nonliving thing?
(BONUS +200): How do you know if it is living/nonliving?
NONLIVING
(BONUS): I do not see cells; I know all living things are made of cells.
This is salt crystals under a microscope!
Is this sample multicellular or unicellular?
(BONUS +200): How do you know?
UNICELLULAR
(BONUS): I see multiple cells, but they are NOT ALL STUCK TOGETHER and NOT IN A REPEATING PATTERN
Look at the image below. Which instrument will I have to use to study something that is 50-100 nanometers (nm) big?
electron microscope
