Answer
A typical bacterial cell diagram includes the following labeled structures:
Cell Wall: The outer layer providing protection and shape.
Cell Membrane: A selectively permeable layer surrounding the cytoplasm.
Cytoplasm: A gel-like substance where cellular processes occur.
Ribosomes: Tiny structures where protein synthesis occurs.
Nuclear Area (Nucleoid): Where the bacterial DNA is located.
Plasmids: Small circular DNA molecules that can replicate independently.
Make sure to draw this diagram large and clearly label each part.

Answer
When environmental conditions return to normal, the endospore's wall breaks down, allowing it to germinate and form new bacterial cells.
