Taxonomy is the science of classifying and naming organisms. Taxonomy
The two-word scientific name for every species on Earth Binomial Nomenclature
Homo sapien (humans) Homo is its genus Sapien is its species Genus and species
Sula sula Dicrurus fortificus Tyrannus melancholicus Elanoides forficatus Which would be closely related to Tyrannus fortificus ?
One way is by an organism’s life cycles, or how it grows and reproduces How do we define kingdoms?
Binary fission, which is essentially cloning This is asexual reproduction asexual reproduction Archaebacteria and Eubacteria
If the environment is too harsh, the bacteria can form spores or cycsts Both are forms of dormancy (remember that word?), which means life processes slow and no reproduction occurs Harsh environments
If bacterium reproduces ever 20 minutes, how many daughter bacteria will exist after 2 hours? Thought Question 1
Significant decomposers (heterotrophs) They have many different ways of reproducing 1. Asexual reproduction 2. Sexual reproduction Fungi
Spore-flinging They grow where they land and extend string-like structures called hyphae into the soil or whatever food source on which they land Asexual reproduction in fungi
When two hyphae meet, the cells fuse like in plant or animal fertilization They then form sporgania to fuse the nuclei The sporangia undergo meiosis and form haploid spores, which the fungus releases to grow again Sexual reproduction Sexual reproduction in fungi
What does it meant to say that the fungus is haploid? How does it differ from a diploid organism? Thought Question 2
Yeast reproduce asexually through budding- similar to binary fission, except the cell does not split in two budding- The genetic material is copied multiple times, then split off from the parent to create many new, genetically identical “babies” Budding
These can include algae, mosses, ferns, and flowering plants They have alternating haploid and diploid stages of reproduction In every class the embryo is produced by the fusion of gametesfusion of gametes Plants
If human embryos were triploid, how many chromosomes would each cell have? Thought Question 3
