The pili allows bacteria to colonize cells or environmental surfaces. It also allows bacteria to hang on and avoid flushing.
Remember that as the diameter of a spherical cell increases, the surface area increases as the square of the diameter, and the volume increases as the cube of the diameter, so volume increases much faster than surface area. The same principle applies for other shapes than spherical cells, but the math is more complicated.
No to cannot live without cell division because our cells need to divide to make us grow. Also we need cell division to survive because our cells only live for a limited amount of time, so if our cells don't divide then the cells will just die and we won't survive.
Cell have a greater surface area to volume rations than a larger cell.
Answeran erythrocyte, or red blood cell (approx. 5um). This forces the blood cells to pass through in single file, maximising oxygen diffusion efficiency.***Average diameter of an erythrocyte is 7.8 micrometerAverage calibre (diameter of the lumen) is 5-10 micrometerThis means that the diameter of an average erythrocyte is smaller than the calibre of the narrowest capillaries. Young erythrocytes can be deformed into any shape. The old lack such deformability, hence, their membrane rupture during their passage especially through splenic capillaries. Their lifetime is 120 days. If we are hopeless to need the old ones, then the spleen will be removed.ahmetcorak
Generally speaking bacterial cells (about 2 micrometer diameter) are much smaller than eukaryotic cells (about 25 micrometer diameter). Therefore a bacterial cell is smaller.
The human epithelial cells are thick and boxlike whereas elodea cells are thin and platelike. The cells of elodea are rigid and rectangular in shape.
there are many cells that can be derrived via hematopoesis initially you have the stem cell, it can be turned into endotheliel cells, fibroblasts, adipocytes, macrophages, dendritic cells, neutrophils, eosinophils, basophils, erythrocytes, platelets, plasma cells, b cells, T cells and monocytes
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
Bacterial cells are prokaryotic and the cells of an onion are eukaryotic.
Skin cells. Epithelial cells
Bacterial prokaryotic cells are about 1-2 microns in diameter and 10 microns long.
Epithelial cells cover the surface of the intestine.
Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
Epithelial cells are the outer cells of the skin.
Epithelial cells
Squamous , cuboidal , stratified , columnar , pseudostratified are types of epithelial cells .
