Document Summary
Cells can be organisms (unicellular), or units in a multicellular organism. Constructed out of same chemical building blocks. Eukaryotic cells: nucleus, membrane-bound compartments with specific functions. Organelle: any structure which occurs in cells and has specialized function. Ribosomes = ribosomal rna, ribosomal proteins (are organelles as well) Wrong nodes split into 3 instead of 2 - bifurcating (original one) As long as using unscaled trees, lines that end early (shorter lines) are not extinct. As lo(cid:374)g as pi(cid:272)ture fits data, it"s acceptable. Biological diversity measured in terms of species number. Definition of species = human construction: we decide what a species is. Species = interbreeding group of diploid reproductively isolated organisms that produce fertile offspring. Some genetic material may not come from parent.
