prokaryotes-vs-eukaryotes-what-are-the-key-differences-336095-1280x720_62ffcab3262fd.jpg
a
Organelles are specialized for cellular respiration while organs are specialized for breathing.
b
Organs are specialized for metabolism while organelles are specialized for homeostasis.
c
Organelles are similar in structure to organs.
d
Organelles have similar regulatory functions to organs.
Question 2
How is a mitochondrion's structure related to its function?
a
The mitochondrion's internal membrane is rigid, which prevents repetitive reactions from occurring inside.
b
The complex folding pattern of the mitochondrion's membrane provides transportation of waste materials, which are directly removed to the outside of the cell.
c
The complex folding pattern of the mitochondrion's inner membrane provides many sites where reactions can occur.
d
Mitochondria have a random folded membrane to increase rigidity and maintain cell shape.

b
Water will neither enter or exit the cells and their sizes will remain the same.
c
Water will exit the cells and cause them to shrink in size.
d
Water will enter the cells and cause them to grow in size.
