How does a cell's ratio of surface area to volume change as the cell grews large?
It will decrease. In a larger cell, you have less surface area per volume.
What is an advantage of a small cell over a large cell?
smaller surface area
How has red blood cell adapted to membrane surface area?
The red blood cell's biconcave shape increases its surface area for diffusion. The lack of a nucleus makes this shape possible.
How does gas exchange happen in capillary blood vessels?
It is because the capillary wall is only one-cell-thick. In addition, they have a large total surface area in contact with body cell and the blood flow is low.
How will surface area to volume ratios of a small cell compare to those of a large cell?
A small cell will have a larger surface-to-volume ratio.
What does the zone of cell elongation do?
provides a large surface area for transportation
What cell has a large surface area to absorb water quickly?
Tissue
What adaptations might help a very large cell survive?
The surface area of large cells is very small without an adequate adaptation. Large cells have many cell folds or Crista within their cell membranes and within the cell to maximize cell's surface area which speeds up the process of cellular metabolism.
Why is there a dip in the centre of a red blood cell?
To increase the surface area so that the blood cell can carry more haemoglobin and, therefore, oxygen.
Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
Which cell has the greater surface area compared to its volume the large cell or one of the smaller cells?
A smaller cell has a higher surface area to volume ratio. A reason for this is volume is cubic (3D) and surface area is 2D so when surface area increases a little bit, the volume increases exponentially. And when the surface area shrinks a little bit, the volume decreases exponentially.
Why is the erythrocyte sedimentation rate low with sickle cell anemia patients?
because the sickle cell has small surface. and the ESR is proportional to surface area of red blood cell.
