  • Mitosis - Microtubules attach to centromeres. Chromosomes align at the mid
    Metaphase
  • Having two sets of chromosomes (2n), characteristic of a sporophyte generation of a life cycle
    Diploid
  • specialized body within eukaryotic cells. Bound by a double membrane. Contains chromosomes.
    Nucleus
  • a taxon descended from a single ancestor = clade
    Monophyletic group
  • mitosis No microtubules. Nucleus reform. Cell wall present
    Telophase
  • Mitosis -Chromosomes condense
    Prophase
  • cellular division: duplicated chromosomes divide resulting in 2 identical daughter cells.
    Mitosis
  • The structure that carries the genes
    Chromosome
  • a monophyletic group made up of an ancestor and all of its descendents. = monophyletic group
    Clade
  • taxa that share an immediate common ancestor
    Sister taxa
  • an organism’s genetic characteristics
    Genotype
  • a unit of heredity, a DNA sequence that codes for a specific protein
    Gene
  • character trait that arose from a common ancestor of a group that is now present in all members of the group. A shared trait
    Synapomorphy
  • Having only one set of chromosomes.
    Haploid
  • derived trait
    Apomorphy
  • mitosis- Sister chromatids separate
    Anaphase
  • genetic information, that self replicates: composed of nucleotides denoted by A,C,G,T
    DNA
  • an organism’s physical characters: an expression of genes.
    Phenotype
  • Mitosis- DNA doubles
    Interphase
  • general term for any taxonomic category: class/order/phylum
    Taxon
