Milestone Minutes Organisms Week 2
Plants obtain energy through the process of photosynthesis Occurs in the chloroplast, chlorophyll (pigment) traps sunlight CO2 is used to make sugars that will be used to make cellulose for cell walls Sunlight + H2O + CO2 => C6H12O6 + O2 Animals obtain energy through the process of cellular respiration. Occurs in the mitochondria. Sugars in food are broken down to make Adenosine Tri-Phosphate (ATP) ATP is stored energy, ADP is released energy. ATP and ADP are cycled by plants and animals C6H12O6 + O2 => ATP + H20 + CO2 Plant and animals are dependent upon each other for life and recycle energy products.
There are six kingdoms of life: Archebacteria- prokaryote, live in oxygen-free environments Eubacteria- prokaryotes, auto-/heterotrophic, some cause disease Protista- uni-/multicellular, eukaryote, heterotrophic, some are parasitic Fungi-multicellular, eukaryote, heterotrophic, decomposers Plant-multicellular, eukaryote, autotrophic Animal-multicellular, eukaryote, heterotrophic Viruses are not considered living because they need a host.
Taxonomy is the classification of living things based on similar characteristics. The taxa groups are kingdom, phylum, class, order, family, genus and species. The more taxa organisms share in common, the more similar they are Additional kingdoms were realized with the discovery of the microscope Binominal nomenclature is the process of naming organisms developed by Linnaeus Scientific names are written in Latin and include the Genus name followed by the species name Body structures, behaviors, and DNA can be used to compare relationships between organisms
