Bacteria and Viruses
The two domains of prokaryotes are known as:
What is Archae and Bacteria
What is the simplest invertebrate known for having asymmetry?
What is porifera or sponge
five groups of vertebrates
What are fish, amphibians, reptiles, birds, mammals
A virus is not considered a living thing because...
(name 2 reasons)
It cannot reproduce on its own
It is not made up of cells
They don't grow
They cannot produce energy
What are 2 things plant-like protists have in common with plants?
photosynthesis, eukaryotic
Stage of plant life cycle that produces the spore
What is a sporophyte
Name two characteristics of most invertebrates .
no backbone
soft bodied, may have an exoskeleton
marine invertebrates have radial symmetry
Two defining features of vertebrates
notochord (nerve cord), most (except a very few species) have a complete backbone of vertebrae, bones, endoskeleton
One difference between the two domains of prokaryotes
archae cell walls have different molecular structure (chemical make-up)
archae thrive in extreme environments
How do fungi obtain and digest food and reproduce?
What is hyphae
structure that transports water up from the roots of plants or nutrients throughout the plant from the leaves
What is vascular tissue
clams (bivalves), snails, octopuses are part of this invertebrate group
What are mollusks
List three characteristics of ALL birds
feathers, hollow bones, wings, beaks
How are prokaryotic cells different from eukaryotic cells? (2 ways)
DNA in cytoplasm, not in a nucleus
no membrane-bound organelles
What are two defining characteristics of fungi?
heterotrophs (decomposers)
cell walls
A hard exoskeleton and jointed appendages are defining features of:
What are arthropods
Three distinctive features of mammals
give live birth, fur/hair, mothers feed their young milk
How do viruses reproduce?
inject DNA into host cell. Host cell copies viral DNA and protein coat.
What are mychorrhizae?
a symbiotic relationship between fungi and plant roots
What are the reproductive structures of Gymnosperms:
cones
Name 4 of the 6 characteristics most animals share
multicellular, consumers, specialized parts,
movement, need to maintain body temperature
most reproduce sexually
Explain the difference between an innate and a learned behavior AND give an example of each
Innate is a behavior done without teaching or experience. Learned is a behavior taught by a parent or other member of the species OR learned from experience
Any acceptable example
