Bacteria to Plants 2 Flashcards

Terms Definitions
flagella
whiplike tails
zygote
a fertilized egg
Organism
a living thing p7
Francesco Redi
believed in spontaneous generation
budding
asexual reproduction. No spores produced, instead a small yeast cell that grows from the body of a parent cell
asexual reproduction
unicellular undergo budding, when moisture and food are adequete, the fungi reproduces by growing fruiting bodies which release thousands of spores
virus
A small, nonliving particle that invades and then reproduces inside a living cell
Hyphae
the branching, threadlike tubes that make up the bodies of multi cellular fungi p89
Bacteriophage
a virus that infects bacteria (bacteria eater)
aerobe
an organism that uses oxygen for respiration
angiosperm
a flowering plant that produces seeds enclosed in a protective structure
vaccine
a substance that stimulates the body to produce chemicals that destroy viruses or bacteria
biomial nomenclature
the scientific naming of species giving each species a latin name having 2 parts (genus, species)
Antibiotic
a chemical that can kill bacteria without harming a person's cells p62
stamens
the male reproductive parts within a flower's petals
generation
the act of producing offspring or multiplying by such production
heterotroph
organisms that cannot make their own food
(hetero=other troph=feeder)
Eukaryote
An organism with cells that contain nuclei and other cell structures.
pseudopod
a "false foot" or temporary bulge of the cell membrane used for feeding and movement in some protozoans
genetic engineering
the process of altering an organism's genetic material to produce an organism with qualities that people find useful
natural selection
the process in which organisms with favorable traits are more likely to survive and reproduce
Species
A group of similar organisms that can mate and produce fertile offspring in nature.
Flagellum
a long, whip like structure that helps a cell to move p49
binomial nomenclature
the naming system for oranisms on which each organism is given a two-part name - a genus name and a species name
Biologist, classificaton, seperate, groups
_____________ use ____________ to ______________ living things into ___________ so that tehey are easier to study.
Prokaryote
An organism whose cells lack a nucleus and some other cell structures
Sexual reproduction
the process by which a new organism develops from the joining of two sex cells p9
spontaneous generation
A mistaken idea that living things can arise from nonliving sources (like flies being "born" from rotting meat)
what does a pseudopod do?
pseudopods help organisms move and eat. An organism will grow two pseudopods to trap food. A pseudopod acts as a foot to help an organism move.
how do protists differ from archaebacteria and eubacteria
because they all differ and they are eukaryoter which are cells that contain nuclei (A&E have no nucleus) (Eukaryotes have a nucleus)
