Compartmentalization

Which of the following best explains how compartmentalization within a cell “improves efficiency” of cellular processes

• A cell that has external membranes that decrease competing interactions

• Compartmentalization within a cell results in a high SA:V ratio

• It minimizes the surface area where cellular processes occur

• Has internal membranes that increase competing interactions within the cell

Compartmentalization means a cell

• has membrane bound organelles.

• is undivided.

• is simple.

• All of the above

the membranous compartmentalization of a cell

• divides the cell into two equal halves

• allows different chemical conditions in the cell

• requires the presence of a cell wall

• common to prokaryotes and eukaryotes

Which of the following questions would best help determine if a cell has membrane-bound organelles?

• Does the cell replicate genetic information?

• Are there ribosomes present within the cell?

• Are there different environments within the cell?

• Does the cell have a selectively permeable membrane?

Membrane-bound organelles have been an important component in the evolution of complex, multicellular organisms. Which of the following best summarizes an advantage of eukaryotic cells having internal membranes?

• Eukaryotic cells are able to reproduce faster because of the presence of organelles.

• Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure.

• Organelles isolate specific reactions, increasing metabolic efficiency

• Compartmentalization leads to a higher mutation rate in DNA, which leads to more new species.
