Not all calls are small. Slime molds for example have gigantic cells with tens of thousands of nuclei in each.
every one but stem cells. which remain undifferentiated
No, all multicellular organisms have the same size cells.
Blood proteins and blood cells are indeed too large to pass through the filtration membrane in the kidneys. During the process of filtration in the kidneys, small molecules like water, electrolytes, and waste products are filtered into the urine, while larger molecules like blood proteins and cells remain in the blood. So, they should not normally be found in the filtrate that is eventually excreted as urine.
There are trillions of cells in the body so, they have to be extremely small to fit.
In leukemia, a small proportion of bone marrow stem cells become malignant and start producing abnormal cells. These abnormal cells then grow uncontrollably, crowding out normal blood cells. The majority of bone marrow stem cells remain healthy and continue to produce normal blood cells.
because cell has to maintain that ratio in order to absorb more nutrients and for efficient absorption of materials. Cells tend to remain small because it promotes efficient transport. If a size of cell get bigger, it takes a longer time for transport and diffusion.
pholem
No.
Most cells can enter a non-dividing stage called G0 phase. Some examples of cells that have a tendency to remain in G0 phase are mature nerve cells and muscle cells. These cells serve specialized functions and do not need to divide frequently like stem cells or progenitor cells.
his parents were just small.
very small
No. Most of the breakdown occurs within minutes in the mouth and stomach. Very few things that are at all digestible remain intact into the small intestine, and certainly entire cells are not absorbed into the bloodstream.
the G1 phase, dawg!
Yes.
