The main thing eukaryotic cells have that prokaryotic cells do not
What is the nucleus?
How many principles make up the cell theory?
3 principles
Define cells
What are the basic building blocks of all living things?
A single circular chromosome
What is unique about the DNA of a (prokaryotic) cell?
Bacteria
What is a type of a prokaryotic cell?
The powerhouse of the cell
What is the mitochondria?
All organisms are made up of one or more cells
What is a principle of the cell theory?
Ribosomes
What is the organelle that makes proteins, and is the organelle that eukaryotic and prokaryotic cells have in common?
Archea (archaebacteria)
What is a type of a (prokaryotic) cell?
Animalcules (“tiny animals”)
What did Leeuwenhoek call bacteria?
How many cells in a human?
Trillions (about 37.2 trillion cells)
Robert Hooke, Anton van Leeuwenhoek, and Dr. Rudolf Virchow
Who were the three scientists who's observations formed the cell theory?
The first person to discover cells
Who was Robert Hooke?
What is the longest cell in the human body?
Neuron (Eukaryotic)
The nucleoid
Where is DNA located in a prokaryotic cell?
Eukaryotes
What is does the term eukaryotic refer to?
Why is cell theory so important?
It affects nearly every aspect of biology (from how we mange diseases, to our understanding of life and death)
The components that make up a cell and how they are arranged inside it.
What is cellular organization?
Who found the nucleus?
Ernest Rutherford (Eukaryotic)
Where can you find prokaryotic cells?
Almost everywhere!
"Prokaryotes, which include both bacteria and archaea, are found almost everywhere – in every ecosystem, on every surface of our homes, and inside of our bodies! Some live in environments too extreme for other organisms, such as hot vents on the ocean floor"
The largest cell in the world
What is an ostrich egg?
(Mainly considered eukaryotic because of the nucleus)
What are the 3 principles of the Cell Theory?
-All living things are made up of one or more cells
-All the life functions of an organism occur within cells (cells are the basic unit of life)
-All cells come from preexisting cells
What keeps a cell alive?
Its DNA (and organelles)
The type of cell in yogurt
What is a prokaryotic cell?
(Probiotics: a combination of live beneficial bacteria and/or yeasts that naturally live in your body)
How do prokaryotic cells divide?
Through binary fission
The prokaryotic chromosome (a single DNA molecule) first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.
