∙ 7y agoThe high partial pressure of CO2 in cells is due to the fact that cells produce CO2 as a byproduct of metabolism. This CO2 diffuses out of cells into the bloodstream where it is carried to the lungs for removal. In contrast, the environment outside of cells has a lower concentration of CO2, resulting in a concentration gradient that drives the movement of CO2 out of the cells.
The partial pressure of oxygen in the interstitial space of peripheral tissues is typically around 40 mmHg. This level is lower than the partial pressure of oxygen in arterial blood, which is around 100 mmHg. Oxygen diffuses from blood capillaries into the interstitial space to reach cells for metabolism.

Celery stalks become limp and soft when left in a salt solution because the salt causes water to move out of the cells in the celery through a process called osmosis. This loss of water results in the cells becoming dehydrated and the stalks losing their crispness.

A low-pressure cell is typically represented on weather maps as an area where atmospheric pressure is lower compared to surrounding regions. It is often depicted as an elongated oval shape with lines (isobars) indicating the pressure gradient. Low-pressure cells are associated with rising air, cloud formation, and potentially stormy weather.

That depends on whether you are asking about the red blood cells themselves, or the blood as a whole. The fluid portion of the blood will have a O2 partial pressure around 20%, but the red blood cells will have an O2 partial pressure nearing 100%.

Yes, vacuoles are found in both animal and plant cells. In animal cells, vacuoles are smaller and less prominent compared to plant cells, where they can be quite large and play a key role in storing nutrients, maintaining turgor pressure, and regulating the cell's internal environment.

Vacuoles store nutrients and are generally much larger in plant cells compared to animal cells. They help regulate the cell's turgor pressure, store waste products, and maintain an acidic internal pH.
If red blood cells were placed into a beaker with plasma, the red blood cells would absorb the liquid and start to expand due to the osmotic pressure. Eventually, the red blood cells may burst (hemolysis) if the osmotic pressure is too high compared to their structural integrity. This would release hemoglobin into the plasma.
