Cell Theory & History
He is the scientist who first coined the term "cell" after looking at a piece of cork under a microscope.
Who is Robert Hooke?
This organelle acts as the "brain" or control center of the cell, containing the DNA.
What is the nucleus?
This rigid outer layer is found in plant cells but is completely absent in animal cells.
What are chloroplasts?
This is the term for a microscopic organism, which can be a bacteria, virus, or protist.
What is a microbe (or microorganism)?
This is the correct order of biological organization from simplest to most complex: Cells $\rightarrow$ _______ $\rightarrow$ Organs $\rightarrow$ Organ Systems.
What are tissues?
This is the minimum number of cells required to make up a living organism.
What is one (unicellular)?
Often called the "powerhouse" of the cell, this organelle turns food into usable energy (ATP).
What is the mitochondrion (mitochondria)?
Plant cells use these green organelles to capture sunlight and perform photosynthesis.
What are chloroplasts?
Unlike eukaryotes, these simple, single-celled organisms (like bacteria) do not have a nucleus.
What are prokaryotes?
The heart, lungs, and stomach are all examples of this level of organization, made of multiple tissue types working together.
What is an organ?
ccording to Cell Theory, all cells come from these.
What are pre-existing cells?
This thin, flexible barrier surrounds all cells and controls what goes in and out.
What is the cell membrane?
While animal cells have many small ones, plant cells typically have one massive one of these to store water and provide turgor pressure.
What is a vacuole (or central vacuole)?
This type of microbe is not considered alive because it cannot reproduce without a host cell.
What is a virus?
This body system is responsible for breaking down food so that nutrients can be absorbed by your cells.
What is the digestive system?
This German scientist contributed to the cell theory by concluding that all animals are made of cells.
Who is Theodor Schwann?
This jelly-like substance fills the cell and holds the organelles in place.
What is cytoplasm?
Because they lack a cell wall, animal cells generally have this type of shape compared to the boxy, rigid shape of plant cells.
What is irregular, round, or flexible?
Why is it important to find the source of a disease outbreak.

Write down the two main outputs (products) of cellular respiration that cells release after breaking down glucose with oxygen.
What are Carbon Dioxide ($CO_2$) and Water ($H_2O$)? (Energy/ATP is also acceptable).
When using a Lab-Aids microscope, if your eyepiece is 10x and your objective lens is 40x, this is the total magnification.
What is 400x?
hese tiny structures are responsible for making proteins, and they can be found floating free or attached to the Endoplasmic Reticulum.
What are ribosomes?
This pigment inside chloroplasts absorbs light energy and gives plants their green color.
What is chlorophyll?
This type of medication can kill bacteria, but is completely useless against a viral infection like the flu.
What are antibiotics?
What is photosynthesis?
