True
What Cell is this?
Animal Cell
These types of cells are larger and more complex, they contain organelles, and they can be both multicellular and unicellular, there DNA is contained in a nucleus.
Eukaryotes
What cell is this?
Plant Cell
These cells are all unicellular, do not contain many if any organelles, and contain a nucleoid instead of a nucleus.
Prokaryotes
A rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
Cell Wall
True or False
Earth's early atmosphere lacked any oxygen and the environment had freezing temperatures.
False
