why is it important for all biologists to be aware of what diffrent
cells and tissue types look like

When you say "look like" are you referring to a macrosopic view,
meaning to be able to identify tissue types in a dissected specimen
(as brodoc-ga points out in his/her Comment), for example, or
microscopically--meaning to know what cells have a sickle shape, which
have a round shape, that only plants have cell walls which are more
square...that type of thing?

Interestingly, researchers have not yet come to the point where we can
verify the identity of all cells/tissues in the body with 100%
accuracy. You can imagine that there are billions of cells in your
body and each cell/tissue is a little different from the next. To have
the ability to narrow your search for the one or several cells/tissues
by looking at morphology (cell/tissue size, shape, position, color,
etc...) can be very powerful. I have observed that in areas of the
brain, such as the hypothalmus, this can be nearly 100% accurate and
there are researchers that can point to a fairly innocous looking
section of brain and tell you excatly what you are looking at. Once
scientists find the region we are looking for, we can use more
intensive and accurate procedures, such as cell staining and genetic
characterization to verify we are seeing what we are looking for. I
hope this helps...
