The English scientist first to use the word “cells” when describing cork under the microscope.
Robert Hooke (fact: he and Newton hated each other)
100
This is found in all cells and contains instructions to make proteins.
DNA
100
This organelle is only found in eukaryotic cells. Its role is to house and protect the DNA.
nucleus
100
All prokaryotic cells are these types of organisms.
bacteria

What is the difference between smooth and rough endoplasmic reticulum?
rough ER has ribosomes and smooth doesn't
200
The cell theory would not have been formed without this tool.
Microscope
200
A jelly like substance found in all cells in which the organelles or other structures are suspended in.
cytoplasm
200
This organelle is responsible for packaging proteins into vesicles.
golgi apparatus
200
True or False: Bacteria have ribosomes.
true
200
Describe the relationship between the nucleus and the rough endoplasmic reticulum.
The nucleus contains the instructions to make proteins, which travel to the rough ER where proteins are made on its ribosomes, then transported.
300
Name at least 3 scientists that played a role in the formation of the cell theory.
Hooke, Leeuwenhoek, Schleiden, Schwann, Virchow
300
All cells are encased in this barrier. It is an important structure because it determines what enters and leaves the cell.
cell membrane
300
This organelle is a tunnel like structure that aids in the production and transportation of proteins.
rough endoplasmic reticulum
300
How many membrane-bound organelles do prokaryotic cells have?
Prokaryotic cells have ZERO membrane-bound organelles.
300
These structures, primarily used during cell division, can be found in animal cells but are NOT found in plant cells.
centrioles
400
Who discovered that cells divide to make more of themselves?
Virchow
400
These structures are found in all cells and are the site of protein synthesis.
ribosomes
400
What is the function of the chloroplasts?
To harvest energy from sunlight and use it to make glucose.
400
Which came first?
The prokaryote or the eukaryote.
prokaryote
400
What can be found surrounding the cell membrane of plants- what is it made out of and what is its function?
The cell wall can be found surrounding the cell membrane of plants.
It is made out of cellulose, a type of polysaccharide.
The function is to provide support, structure, and protection for the plant.
500
What are the three parts of the cell theory?
1} All living things contain cells.
2}All cells arise from pre-existing cells.
3} Cells are the basic unit and structure of life.
500
A network of fibers that help the cell maintain shape and can assist with cell movement.
cytoskeleton
500
Specialized versions of this organelle include lysosomes and peroxisomes.
vesicles
500
It takes much longer for a eukaryotic cell to replicate (make copies of itself) than a prokaryotic cell.
Based on what you know, hypothesize TWO reasons why it takes bacterial cells less time.
Prokaryotic cells are smaller.
Prokaryotic cells have less “stuff”. They do not have membrane bound organelles and are therefore less complex.

Describe the differences among the vacuoles of plant and animal cells.
In plant cells, the vacuole is a single, central vacuole that is large and stores water.
In animals, the vacuoles are smaller and used to store various substances.
