What is the first principle of Cell Theory?
All living things are made of cells
Organisms can be unicellular or multicellular.
What are the two types of cells?
Prokaryotic and Eukaryotic
Prokaryotic cells lack a nucleus and membrane-bound organelles.
What is the basic unit of life?
Cell
It is the smallest part of an organism capable of all life’s processes.
Do prokaryotic cells have a nucleus?
No
Prokaryotic cells do not contain a nucleus.
Do eukaryotic cells have membrane-bound organelles?
Yes
Eukaryotic cells contain membrane-bound organelles.
How do prokaryotic cells divide?
Binary fission
This is a simple form of asexual reproduction.
What is the size range of prokaryotic organisms?
Microscopic
Prokaryotic organisms are typically very small.
What type of cell division do eukaryotic cells undergo?
Mitosis
This process is more complex than binary fission.
Can eukaryotic cells be unicellular or multicellular?
Both
Eukaryotic organisms include fungi, plants, and animals.
What are the cell walls of prokaryotic cells made of?
Peptidoglycan
This structure is unique to bacteria.
What are the cell walls of fungi made of?
Chitin
Plants have cellulose walls
What do all cells have?
Genetic material (DNA or RNA), Cytoplasm, Cell membrane
These are fundamental components of all cells.
What is the third principle of Cell Theory?
All cells come from other cells
This principle emphasizes the continuity of life.
