Re: What would happen to a cell if it did not have any vacuoles in it?

First of all, I want to note that not all cells do have vacuoles, most do, 
but there are a few animal cells that appear to lack vacuoles.  They are of 
greatest importance in plant cells where they perform several essential 
functions, I am going to focus the answer to your questions on plant 
cells.  If a plant cell were to lack vacuoles the result would be that the 
cell would be extremely limited in its ability to interact with its 
environment since the vacuoles are used for transporting and storing 
nutrients, metabolites and waste products for movement in and out of the 
cell.  Basically, without vacuoles the cell would be unable to take in 
signals from the outside, send out sigals or store metabolic and waste 
materials.  It would also not be able to stand rigid since the turgor 
pressure is maintained within vacuoles; without the vacuoles huge amounts 
of cytoplam would be needed to maintain growth of the plant cell.  Without 
vacuoles, the cell might be in danger of poisoning itself since the 
vacuoles often store essential molecules that are potentially harmful if 
present at high concentration in the cytoplasm.  Finally, without vacuoles, 
it would be difficult for plants to propogate themselves since the 
nutrients found in seeds are stored in vacuoles until needed.
