Flashcards in The Diversity of Cellular Life/Prokaryotic & Eukaryotic Cells Deck (11)
Loading flashcards...
1
Unicellular organisms
Have one cell
2
Colonial organisms
Unicellular organisms that live together in a group - no relationship to each other
3
Multicellular organisms
A group of cells that live & work together in one organism - dependent on each other because differentiation & specialization
4
Advantages of specialization in multicellular organisms
Each cell only has one job so it can be more efficient at it
5
Disadvantages of
Cells are dependent on one another - if one cell fails to do its job the whole organism will perish
6
All cells have two characteristics in common
They are surrounded by a cell membrane & they contain DNA
7
Prokaryotic cells
Lack a nucleus and membrane-bound organelles, also have a cell wall
8
Prokaryotic cells example
Bacteria
9
Eukaryotic cells vs prokaryotic cells
Eukaryotic cells are generally larger & more complex
10
Eukaryotic cells
Have a nucleus and membrane-bound organelles
