Diversity of Life Lecture Notes IViruses, Bacteria, Fungi, Protists and Plants
Classifying Organisms ___________________: The scientific study of how an organism is classified. Levels of classification(see picture) The more levels of classification shared, the more characteristics they have in common!
Species with similar _____________________ histories are grouped together
3 Domains of Life
Viruses
Tiny, _______________________ particle that enters a ________ cell and reproduces its genetic information They can only multiply when they are inside a living cell! Structure
1. _____________ coat for protection 2. Genetic material (______________________)
They can either be ‘active’ or ‘hidden’ Harmful and helpful (causing diseases and curing diseases with
biotechnology)
Bacteria
_________________ (no nucleus or membrane bound organelles) Can be autotrophic or heterotrophic Need to go through cellular respiration for _______ Reproduce by ___________________________ Important organism to put ____________ on this Earth! Also used to make lots of food and medicine…(yogurt, insulin)
Protists
Eukaryotes that cannot be classified as animals, plants or fungi! Very ______________ grouping Unicellular or multicellular, various types of mobility, heterotrophs or autotrophs Animal like proists: _________________ Plantlike protists: ______________ Funguslike protists: Molds and mildews
Fungi
Eukaryotes with cell walls Heterotrophs by _________________ their food (release digestive enzymes and absorb
it through the hyphae) Use ___________ to reproduce (tiny cell that’s able to grow into a new organism) Reproductive structure where spores are released: __________________________ Hyphae make up the bodies of fungi (substances can move through) Positive and Negative: Cause diseases and act as decomposers!
Plants
____________________ that go through photosynthesis (Have chloroplasts ) __________________ to store water (shrinks and expands) Life started in water but plants adapted to living on land!
__________: waterproof layer to retain water A way to transport material Support Reproduction
Nonvascular Plants
Lack a well developed system of tubes for transporting water and other materials _______________________ (not more than a few cm. high) Live in ___________ shady places
Vascular Plants
Better adapted to life in dry areas. _______________________ to transport water and materials Seedless: Reproduce with spores Gymnosperms: Reproduce with ____________ (no flowers or fruit!) Angiosperms: Flower and reproduce with seeds that are surrounded by ______________
