1. as a group, write a definition for a prokaryotic cell.

1. as a group, write a definition for a eukaryotic cell.

1. complete the phrase below. each member must contribute one complete sentence. the words prokaryotic and eukaryotic must be used:

all cells are not the same because...

1. as a group, discuss the opening analogy of an efficiency apartment and a mansion as it relates to cells. record your final consensus of how this analogy applies to cell structure.

Explanation:

1. All cells have a cell - membrane, ribosome, cytoplasm, and DNA. Bacterial cells are prokaryotic, lacking mitochondria, a nucleus, and a nucleolus. Animal and plant cells are eukaryotic. Plant cells have a cell wall, while animal cells do not.
2. A prokaryotic cell is a cell that lacks a true nucleus and other membrane - bound organelles.
3. A eukaryotic cell is a cell that has a true nucleus enclosed by a nuclear membrane and other membrane - bound organelles.
4. All cells are not the same because some are prokaryotic with simple structures lacking a nucleus, while others are eukaryotic with a defined nucleus and various organelles.
5. The efficiency apartment can be compared to a prokaryotic cell, which is simple and has basic functions. The mansion can be compared to a eukaryotic cell, which is more complex with specialized compartments (organelles) for different functions.

Answer:

18.

	Bacterial Cell	Animal Cell	Plant Cell	All Cells
Ribosome	yes	yes	yes	yes
Cytoplasm	yes	yes	yes	yes
Mitochondria	no	yes	yes	no
Nucleolus	no	yes	yes	no
Nucleus	no	yes	yes	no
DNA	yes	yes	yes	yes
Cell Wall	yes	no	yes	no
Prokaryotic	yes	no	no	no
Eukaryotic	no	yes	yes	no
