Question Answer
Diagram of Staphylococcus
Diagram of Streptobacillus
How is bacteria helpful? - makes food such as yogurt and cheese - gut bacteria helps digest food
Lytic cycle vs Lysogenic Cycle -Lyctic Cycle: - virus takes over the cell, only producing the parts to assemble the virus, not the parts necessary to keep the cell alive - Lysogenic Cycle: - viral genes are incorporated into the host cells DNA, every time the host cell copies itself, a copy of the virus is made. Cell is kept alive
Why are viruses difficult to classify? - Viruses are difficult to classify because they have DNA, adapt to their environment but aren't alive
Why aren't viruses considered alive? - Viruses aren't considered alive because they arent made out of cells and can't reproduce on their own
Viruses vs. Prokaryotes and Eukaryotes - Viruses don't reproduce on their own, prokaryotes and eukaryotes do through mitosis and meiosis - Viruses have no organelles - Prokaryotes and Eukaryotes are alive
3 Classifications of Protists and their Characteristics - Animal like, Plant like and Fungus like - animal like: heterotrophs (captures and ingest food) - Fungus like: heterotrophs (mostly feed on decaying matter) - Plant like: autotrophs (produce their own food), contain chloroplast for photosynthesis
