I overheard a rather heated argument about whether or not animal cells have vacuoles.
One person said that they do, but they're much smaller than vacuoles in plant cells.
The other person said they don't. While there is something there that acts similar to a vacuole, it's slightly different. The person also noted that the only websites that say that something as a vacuole aren't credible sites (ie. not University sites, etc...)
I'm really curious as to which it is: Do animal cells have vacuoles or not?
