Flashcards in The Diversity of Cellular Life/Prokaryotic & Eukaryotic Cells Deck (11):
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

11

Eukaryotic cells example

Plants, animals, protists, and fungi
