Unit 2 test
what are saprohysic
will eat dead or decomposing matter
What's heterotrophic
Needs to find food the food source
Are fungi heterotrophic or autotrophic
Heterotrocphic
what is autotrophic
creat their own food source
3 major groups of fungi
Mushrooms
Yeast
Mold
Why do we call mushrooms the dogeztive track of the forest
they can break down anything thats dead or decomposing.
What is Mycelium
made up with white filaments. composed of long threads that enter into the ground. The mushroom is what you see above.
How many species of fungi exist (approximatley)
1.5 million species
What are domains of prokaryotes
Bacteria, Archaea
what do Prokaryotes and Eukaryotic have in common
DNA, Ribosomes, Cytoplasm, Cell membrane
6 kingdoms
Archaea, bacteria, animals, plants, protists, fungi
What is Taxonomy
The science of the classification of all living organisms
What is the diagram that describes the relastionship between groups and organisms
Cladistic
What is Protists
belongs to the domain eukaryota. Can not be placed in another kingdom. Really hard to share similar characteristics.
what is charactiestics protozoans
Heterotropic, most can move, live in wetlands, Parastic, Different kinds.
What part of the bacteria cell helps it move
Flagella
What part of the bacteria helps it stick to surfaces
Pilus
what is the function of the cell wall (bacteria)
Protects the cell and gives it shape
What is on the inside of the cell wall (bacteria)
Cell membrane
What is the watery interior of the cell (bacteria)
Cytoplasm
Thoughtout the cytoplasm there are what? (bacteria)
Ribosomes
what is the endosymbiotic theory
it explains how eukaryotic cells evolved from prokaryotic cells through symbiosis.
who is carl linnaeus
the father of modern taxonomy
what is the classification of humans
domain:eukarya, kingdom:animalia, phylum:chordata, class:mammalia, order:primates, family:hominidae, genus:homo, species:homosapiens
what is a cladogram
a diagram that demonstrates the evolutionary relationships between groups of organisms.
what is binomial nomenclature
a system of naming species
how binomial nomenclature works
first word starts with a capital letter (Genus) the second word is all lowercase (species) (eg: Homo sapiens)
kingdom protists - Amoebas (how do they move?)
by stretching its cytoplasm into fingerlike extensions called pseudopodia.
kingdom protists - macro/micronucleus
the macronucleus is large and and controls cell activities, the micronucleus is small and only used for sexual reproduction
cilia vs pilus (whats the difference?)
cilia is found on cells whereas pilus is found in bacteria
what is the oral groove
typically found on paramecium, it leads to thr mouth and helps direct food particles
3 domains
archaea, bacteria, eukarya
what is a dichotomous key
a tool used to identify organisms and objects by answering questions that lead to the correct name or classification
Is the paramecium unicellular or multicellular
Unicellular
What kindom does paramecium belong to?
Kindom Protist
What does paramecium eat?
Algae and bacteria
How does a paramecium move?
using vibraiton of their cilia
What is conjugation
2 paralemecuim exchanging DNA (reproductin)
What is the function of the contractile vacuole (paramecium)
Remove water
What is the function of the Trichocysts
make the cell look bigger to scare off pretedors
where do paramecuim live
Ponds
hiw does the ameba reproduce
Mitosis
Zooflagellates use what to move/feed
Flagella
