Question 1

Robert Hooke

Accepted Answer

Discovery date:  1665.
Came up with the word “the cell”.

Question 2

Hans and Zacharias Janssen

Accepted Answer

Discovery date:  End of the 16th century.
Made the first-ever compound microscope along with the first telescope.

Question 3

Matthias Schleiden

Accepted Answer

Discovery date:  1838.
Came up the word “the cell theory”.  He liked to study plants under a microscope because he was a botanist.  Then he finally realized that every plant he was looking at was made of cells.

Question 4

Theodore Schwann
(Zoologist)

Accepted Answer

Discovery date:  1839.
Came up with a nerve cell named after him.  Also invented rebreathers, for firefighters.  Came to say that all animals were made of cells.  Matthias Schleiden and Theodore Schwann then came together finally and came up with the ct.

Question 5

Rudolf Virchow

Accepted Answer

Discovery date:  1858.
He did say that cells came from other cells “borrowed without permission”.

Question 6

Anton van Leeuwenhoek

Accepted Answer

Made a microscope like a tiny paddle the size of sunglasses it had to of these.  He discovered bacteria, he called them animalcules.

Question 7

Robert Brown

Accepted Answer

Discovery date:  1828.
After noticing moving particles (now known to be amyloplasts, organelles involved with starch synthesis) suspended within living pollen grains of Clarkia pulchella, he examined both living and dead pollen grains of many other plant

Question 8

What instrument or technology was necessary before the cell theory could be discovered?

Accepted Answer

A microscope with light or an electron microscope.

Question 9

When was the compound light microscope discovered?

Accepted Answer

The late 16th century.

Question 10

When was the electron microscope discovered?

Accepted Answer

1931.

Question 11

Which three scientists directly contributed evidence for the cell theory?

Accepted Answer

Shelden
Schwann
Virchow

Question 12

List the three parts of the cell theory.

Accepted Answer

All organisms are composed of one or more cells.
The cell is the basic structural and organizational unit in organisms.
All cells come from preexisting cells.

Question 13

Why did it take scientists so long to develop the cell theory?

Accepted Answer

It took so long because there were no phones back then and they had to send letters back and forth.

Question 14

Cells combine to form:

Accepted Answer

Tissues

Question 15

Tissues combine to form:

Accepted Answer

Organs

Question 16

Organs combine to form:

Accepted Answer

Organ Systems

Question 17

Organ Systems combine to form:

Accepted Answer

Organisms (living things)

Question 18

Do Prokaryotic cells have a nucleus?  What would be an example of a  Prokaryotic cell?

Accepted Answer

No, bacterial cells are prokaryotic.

Question 19

Do Eukaryotic cells have a nucleus?  What would be an example of an Eukaryotic cell?

Accepted Answer

Yes, all animal and plant cells have a nucleus.

Question 20

Cell Membrane

Accepted Answer

Found in all cells, made of two layers of lipids (lipid bilayer), is selectively permeable, means that some molecules can pass through this membrane and some cannot.

Question 21

Nucleus

Accepted Answer

Contains DNA in the form of chromatin, Chromatin DNA that has been slightly packed together, covered by a membrane with pores (holes), allows RNA and ribosomes to leave the Nucleus.

Question 22

Nucleolus

Accepted Answer

Inner region of the nucleus where ribosomes are produced.

Question 23

Golgi Apparatus

Accepted Answer

Flattened membrane sacs that “package” and distribute proteins that have been made by ribosomes.

Question 24

Ribosomes

Accepted Answer

Small organelles that “read” RNA in order to produce peptides (proteins).  The proteins are built by joining amino acids together.

Question 25

Animal Vacuole

Accepted Answer

Small and TEMPORARY sacs that contain water and waste.

Question 26

Plant Vacuole

Accepted Answer

Large and PERMANENT sac that stores mostly water and some waste.

Question 27

Mitochondria

Accepted Answer

Produces energy (in the form of ATP) by breaking down food molecules during cellular respiration.  Has an outer membrane and an inner membrane.

Question 28

Smooth Endoplasmic Reticulum

Accepted Answer

Produces Lipids, and detoxifies the cell.

Question 29

Rough Endoplasmic Reticulum

Accepted Answer

Network of connected membranes that help to move proteins and other molecules throughout the cell.  Has Ribosomes attached to it.

Question 30

Lysosomes

Accepted Answer

Small, round organelles that contain digestive enzymes.  They break down old organelles and other cellular waste.

Question 31

Centrosome and Centrioles

Accepted Answer

Produce spindles called microtubes that help animal cells split their DNA (in the form of chromosomes) and pull apart during cell division.

Question 32

Cell Wall

Accepted Answer

Provides additional structure and support to the cell.

Question 33

Chloroplast

Accepted Answer

Perform photosynthesis to produce food molecules (Glucose).

Question 34

Found only in animal cells:

Accepted Answer

Lysosomes, Centrioles, Small Vacuole

Question 35

Found in both animal cells and plant cells:

Accepted Answer

Cell membrane, Nucleus, Ribosomes, SER, RER, Golgi, Mitochondria, Nucleolus, Nuclear Membrane, Cytoplasm

Question 36

Found only in plant cells:

Accepted Answer

Chloroplast, Cell Wall, Large Vacuole

Living Environment
