Or. Foyez Samar
The volume enclosed by the plasma membrane of plant cells is often much larger the c
corresponding volume in animal cells. The most regsengble explanation for this observation Is that
A) plant cells are capable of having a much higher surface-to-volume ratio than animal cells.
B) plant cells have a much more highly convoluted (folded) plasma membrane than animal cens.
C) plant cells contain a large vacuole that reduces the volume of the cytoplasm.
D) animal cells are more spherical, whereas plant cells are elongated.

Molecular Transport Across Membranes Workshop
How does the cell membrane control movement of materials?
The cellular membrane is critical to the maintenance of homeostasis in living
organisms. The cell membrane separates the cell from the external environment and
plays a critical role in regulating movement of material in and out of the cell.
Additionally, eukaryotic cells are made complex by the presence of internal
membranes that form organelles, so the cells may become specialized. These organelle
membranes create compartments within the cell that can do specific functions.
For this exercise, you will work in groups of four to progress through the activities.
At the end of each activity, one group (chosen at random) will share how they
responded and open the floor for further discussion.
