Cell Theory
All _________________ are made of cells.
living things
Bacteria and protists are these types of organisms (uni or multi)
Unicellular
Protists, fungi, plants, and animals are _________.
eukaryotes
The basic structural and functional unit of life
Cell
Alive or Not: Potato chips
Not (but delicious!)
The cell is the most basic unit ____________.
of life
These organisms have groups of cells that work together to form tissue, organs, and organ systems to carry out life functions. (uni or multi)
Multicellular
The area within a prokaryotic cell where the DNA is found.
Nucleoid
An organism consisting of one cell
Unicellular
Which is not multicellular:
Bacteria
Humans
Plants
Cats
Bacteria
All cells arise from ___________________.
preexisting cells
The tail like structure extending out of the side of a unicellular organism is called this.
Flagellum
This is the most defining feature of a prokaryote
no nucleus
States that the cell is the basic unit of all living things
Cell Theory
How do scientists determine if something is alive?
It is made of at least one cell.
Cells _____________ in order to made new organisms.
divide or reproduce
Unicellular organisms use these structures to perform life functions.
organelles
These cells are simple and always unicellular.
Prokaryotes
An organism made up of more than one, often different, cells.
Multicellular
How do unicellular organisms get nutrients vs multicellular organisms?
Unicellular organisms use their organelles to take in, digest, process, and excrete waste from nutrients. Multicellular organisms use their digestive system to eat, digest, and excrete waste.
This scientist discovered cells in 1665
Robert Hooke
Both unicellular and multicellular organisms contain this structure around them.
cell membrane
Name 3 organelles found in both prokaryotes and eukaryotes
cell membrane, ribosomes, cytoplasm
Organism whose cells have a true nucleus and membrane-bound organelles
Eukaryote
Name the three tenets of cell theory
1- all living things are made of cells
2- the cell is the basic unit of life
3- cells arice from pre-existing cells
