How do fungi reproduce? |
Back (Definition)
|
|
Ecosystem |
Living in Air, earth, or water. Communities of living and non living things interacting. |
|
Community |
Animals and plants that live in one place |
|
Population |
One specific species |
|
What are the two types of cells |
Prokaryotic and Eukaryotes |
|
Prokaryotic |
smaller, simpler. Does not have a membrane-bound nucleus. Includes all bacterial cells. |
|
Eukaryotes |
Larger, complex cell. Have a Membrane-bound nucleus. Plants, animals, fungi, and protist cells. |
|
What are the 3 domains |
Bacteria, Archaea, Eukarya |
|
What are the 6 kingdoms |
Animalia, Plantae, Protista, Fungi, Eubacteria, Archaebacteria |
|
Animalia kingdom |
Multicellular, Eukaryotic Largest kingdom. |
|
Plantae |
Multicellular, eukaryotic. Flowering plants, mosses, and ferns |
|
Protista |
Eukaryotic, Unicellular, and Multicellular. Slime, molds, algae. All microscopic organisms. |
|
Fungi |
Multicellular, Eukaryotic. Mushroom, mold, mildew. Can’t make their own food so they aren’t plants. Get food from dead plant parts. |
|
Eubacteria |
Unicellular, Prokaryotic. Helpful, produce vitamins. |
|
Archaebacteria |
Unicellular, Prokaryotic. Found in extreme environments (boiling water, acid, thermal vents, volcanoes) Ancient bacteria. |
|
Species |
Organisms that can interbreed and produce fertile offspring |
|
What is the 2 name system called |
Binomial nomenclature |
|
What are the two parts of naming a species |
Genus name, and species name |
|
Taxonomy |
Science of naming organisms and assigning them to groups |
|
Systematics |
The study of biodiversity and the relationships among organisms. |
|
What are the 7 taxonomic levels |
Kingdom Phylum Class Order Family Genus Species |
|

|
Phylogeny |
Reconstruction of evolutionary relationships in a “family tree” |
|
Formula for specimen size |
SS = Field view / # of specimens that will fit across your FV |
|
Diagram magnification formula |
DM = size of drawing (mm) / Specimen size (mm) |
|
GRAMMIC |
G - growth and development R - reproduction A - adapt through evolution M - metabolism M - movement I - irritability (responds to stimuli) C - composed of cells |
|
virus |
Small, non-living particles that consist of genetic material surrounded by a capsid Has either DNA or RNA but never both |
|
3 types of viruses |
Baterial : bacteriophage, animal, plant : viroid |
|
Viroids |
Affect the growth and coloration of plant parts (ex. Leaves, petals) Strands or circles of RNA No capsid. |
|
Animal viruses - host range |
1) carrier hosts : virus reproduces but will not harm the host 2) prey hosts : viral reproduction is lethal to the host |
|
The Lytic Cycle |
1) Binding : virus binds or sticks to the surface of host cell. 2) Synthesis : viral genetic materials are released into the nucleus of the host cell to be replicated. 3) Assembly : viral DNA/RNA instructs the cell to make and assemble new viral DNA and capsids 4) Lysis : host cell bursts, the new viruses leave to infect other cells. |

|
Lysogenic Cycle |
Viral DNA is dormant in cell and carried through many generations. Steps. 1) Binding and Attachment 2) DNA/RNA of virus integrated into cell’s DNA but remain inactive 3) Replicated with host DNA and passed onto daughter cells. 4) Dormant stage is called lysogeny. 5) Cycle continues until a trigger happens and the virus can become active or enter the lytic cycle Triggers include: sun, stress, chemicals, radiation etc. |
|
Kingdom Archaebacteria characteristics and 3 phyla |
- oldest of all organisms on earth 3 phyla: anaerobic methanogens, halophiles, thermophiles. Anaerobic methanogens: live in the gut of animals, produce methane gas on earth Halophiles: salt loving bacteria Thermophiles: heat loving bacteria Archaebacteria can survive in hot, acidic, and salty environments. |
|
Kingdom Eubacteria Characteristics |
•unicellular •prokaryotes •single chromosome forms a loop called a plasmid •flagella for transportation |

|
3 basic shapes for bacteria and the 4 prefixes |
1) coccus = round [think coccus has an “o” in it] 2) bacillus = rod [think cill=pill] 3) sprillum = spiral Prefixes mono = one diplo = two strepto = chain staphylo = clump [like grapes] |
|
bacterial reproduction : binary fission |
•asexual reproduction •grow at an exponential rate when given the right amount of nutrients. step 1) chromosomes duplicate and copies get separated. step 2) cell elongates and copies of chromosomes move towards poles. step 3) cell divides into two daughter cells |
|
bacterial reproduction : conjugation |
step 1) donor cell makes contact with recipient cell step 2) conjugation tube forms at site of contact, bridging the 2 cells step 3) single stranded DNA of the plasmid gets transferred into the recipient cell step 4) conjugation tube disconnects |

who created penicillin, what is it, and what does it do? |
•alexander fleming in 1930s •mold juice used to kill bacteria |

|
What are fungi cell walls made from? |
Chitin |
|
Autotroph, heterotroph, and mixotroph |
Autotroph : produce their own food Heterotroph : depend on other organisms for nutrients Mixotroph : both |
|
Evolutionary milestones of animals order |
1. Base definition (heterotroph, diploid, multicellular, develop from zygote) 2. Presence of Radial symmetry (symmetrical all around) 3. Development of bilateral symmetry 4. Development of germ layers (ectoderm, mesoderm, endoderm) 5. Development of body cavity (coelom) to surround and contain internal organs 6. Protostome development 7. Segmentation 8. Jointed appendages 9. Deuterostome development 10. Development of large dorsal nerve cord 11. Backbone
