Question
Chapter 5, Problem 1AC
Summary Introduction
To hypothesize:
The reason that the plasma membrane of a paramecium is permeable to only 1% of water in comparison to human red blood cell and to explain whether paramecium has aquaporins in its plasma membrane.
Introduction:
AQP or aquaporins are the membrane proteins which act as channels for the transfer of water or some amount of solutes. These aquaporins are conserved in animals, plants, and bacteria. Paramecium is a free-living protozoan.

Students have asked these similar questions
What might happen to the contractile vacuoles in a paramecium if the organism were transferred from the culture medium into sea water? Hint use osmosis in your response.
Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings:
A single-celled freshwater protist is placed into a beaker of salt water.
A salt-water snail is mistakenly put into a freshwater tank.
A head of lettuce is placed soaked in a sink of salt water.
A carrot is soaked a sink of distilled, pure water.
If an animal cell was placed in a hypertonic
solution, which answers predict what would NOT
happen?
Osmosis will cause the cell to lose water
The cell will expand and possibly die due to the
gain of salt by diffusion.
The cell will shrivel and possibly die due
The cell will not change
The cell will shrivel and possibly die due to loss
of salt by diffusion.
The cell will develop cancer
The cell will expand and possibly die due to the
gain of water by osmosis.

- Give typing answer with explanation and conclusionarrow_forwardSuppose you are examining osmosis by studying a carrot soaking in water. First, you conclude that the cell walls of the carrot are semipermeable, allowing water molecules but not solutes to passively move into and out of the cell. Next, you measure the solute concentrations of the carrot cells and the surrounding water. You determine the carrot cells contain a higher solute concentration than the water in which the carrot is soaking. Which statement accurately describes this scenario? Group of answer choices The cells of the carrot are hyperosmotic compared to the surrounding water, so water will be drawn out of the cells through osmosis The cells of the carrot are hypoosmotic compared to the surrounding water, so water will be drawn out of the cells through osmosis The cells of the carrot are hypoosmotic compared to the surrounding water, so water will be drawn into the cells through osmosis The cells of the carrot are hyperosmotic compared to the surrounding water, so water…arrow_forwardChoose pne of these choices: A. Water molecules will still be able to move across the cell membrand but at a slkwer rate. B. Water moleces will no longer be able to move across the cell membrane. C. Water molecules will move across the cell membrand at a faster rate without the aquaporin regulating their flow. D. Water molecules will only be able to enter the cell by active transport.arrow_forward

- You said that " However, if the salinity level is too extreme or the exposure is prolonged, it could lead to cellular damage and potentially death. In summary, while marine mussels are adapted to live in a hypertonic environment and are osmoregulators, exposure to extremely high salinity levels could still be harmful to them." Where are you finding this I can't seem to find this on the internet do you have a research paper to show this. Thank you for your help and timearrow_forwardGive typing answer with explanation and conclusionarrow_forwardExplain osmotic balance in cells. What happens to a cell that is placed in a hypotonic solution, hypertonic solution, or isotonic solution? What is special about the maintenance of osmotic balance in halophiles that would allow them to survive in high salt concentrations? What is the natural habitat of archaea species Halobacterium salinarum?arrow_forward
