Document Summary

+ ecology: organism, one individual of a specie, organ systems, parts of body divided, specialized in different tasks, e. g. digestive system vs nervous system, organs, individual organs within organ system responsible for specific job, tissues, cells, organelles. Botany, zoology: molecules occurs in all, leaves, people etc. The cell: the basic unit of life: performs all required activities. Lecture notes: eukaryotic (means true nucleus) e. g. humans, prokaryotic (before nucleus evolved) Archaea: we know very little about archaea, found in intestines. Dna: genetic material: chromatin, working cell, everything in place, settled home analogy, chromosomes, visible, wound up, packed up analogy, chromatin is the dna and proteins that make up chromosomes. Chromosomes are the separate "pieces" of dna in a cell (made up of chromatin). Sister chromatids are identical pieces of dna held identical chromosomes in the newly made cells: passed on from mother cell to daughter cells. Mitosis, plants: passed from one generation to the next.
