Biology: Life is Full of Surprises

The above comic represents a cell, and all living things are made of cells. In fact, a cell is the structural component for all life on earth.

And cells run everything.

There are many different types of cells: Eukaryotic vs Prokaryotic (like bacteria!). Plant vs Animal. In animals, there are skin cells, blood cells, nerve cells, muscle cells, fat cells, and more!  … so many different cells – different structures, different functions, but ultimately all of these cells are making up every level of life on earth.

And the truly important part of knowing about Biology, is that it focuses on life. So, when scientists study biology, they have to decide whether they are interested in studying life at the cellular level, at the organismal level, at the population level (which would only look at a single species), at the community level (where there are many species living together), at the ecosystem level, landscape level, biosphere level, global level…oh my. 

Biologists work from very, very tiny scales using incredibly fined tuned microscopes to very, very large scales such as looking at how life is being affected by a certain factor, perhaps a virus like COVID-19, on a giant global scale.

Perhaps we should just agree that biology is a very large and very diverse field. But that’s a wonderful thing, because it gives you tons of options for deciding what you’re most interested in.
