sc.912.l.14.3 compare and contrast the general structures of plant and animal cells compare and contrast the general structures of prokaryotic and eukaryotic cells.
4 fill in the blank 2 points
complete the following chart for prokaryotes and eukaryotes.

	prokaryotes	eukaryotes
contains cytoplasm	choose your ar	choose your answe
contains a nucleus	choose your ar	choose your answe
contains membrane bound organelles	choose your ar	choose your answe
contains ribosomes	choose your ar	choose your answe
has a cell wall	choose your ar	sometimes choose your answe
has a cell membrane	choose your ar	choose your answe

Explanation:

To complete the chart, we analyze the characteristics of prokaryotes and eukaryotes:

Contains DNA

• Prokaryotes: Yes (DNA in nucleoid region).
• Eukaryotes: Yes (DNA in nucleus and mitochondria/chloroplasts).

Contains Cytoplasm

• Prokaryotes: Yes (gel - like substance in cell).
• Eukaryotes: Yes (fills the cell, holds organelles).

Contains a Nucleus

• Prokaryotes: No (no membrane - bound nucleus).
• Eukaryotes: Yes (has a membrane - bound nucleus).

Contains Membrane - Bound Organelles

• Prokaryotes: No (only ribosomes, which are not membrane - bound).
• Eukaryotes: Yes (e.g., mitochondria, ER, Golgi).

Contains Ribosomes

• Prokaryotes: Yes (for protein synthesis).
• Eukaryotes: Yes (for protein synthesis).

Has a Cell Wall

• Prokaryotes: Most (e.g., bacteria) have cell walls (peptidoglycan).
• Eukaryotes: Plant cells (cellulose), fungi (chitin) have cell walls; animal cells do not (so “sometimes” for eukaryotes).

Has a Cell Membrane

• Prokaryotes: Yes (regulates transport).
• Eukaryotes: Yes (regulates transport, present in all cells).
