Mod. 9 Prokaryotes & Viruses
The science dealing with the description, identification, naming and classifying of organisms
Taxonomy
Tiny organisms that float in the water
plankton
What do we call the study of plants?
Botany
Nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
Xylem
the end of the animal that contains the head
anterior
Naming an organism with its genus and species name
Binomial nomenclature
Name an animal-like protist (a protozoan)
amoeba, zoo flagellates, paramecium, stentor are all examples
A life cycle in which there is both a multicellular diploid form and a multicellular haploid form
Alternation of Generations
Living vascular tissue that carries sugar and organic substances throughout a plant
Phloem
this organism only exists in the polyp stage, one end is covered in tentacles, tentacles are covered in nematocysts used for releasing chemicals into its prey
hydra
This is what we used to classify organisms by phylum, class, order, family, genus and species
A Biological Key
Digestion in fungi - extracellular or intracellular?
extracellular
A system of tube-shaped cells branching throughout a plant that transports materials between roots and shoots
vascular tissue
A plant that loses its leaves for the winter - give the scientific name
deciduous
this phylum contains crayfish, lobsters, spiders, scorpions and insects; all have an exoskeleton
arthropoda
Name one of the bacterial shapes
Round or Coccus, Rod-Shaped or bacillus, spiral-shaped or spirillum
Mycelium
The most abundant members of the gymnosperm group of plants
conifers
How a plant depends on water, ie. what it needs water for - name at least 2 of the 4
photosynthesis, turgor pressure, hydrolysis and transport
the organ of balance in a crustacean
statocyst
A noncellular infectious agent that has two characteristics: 1. it has genetic material (DNA or RNA) inside a protective protein coat and 2. it cannot reproduce on its own; it must infect a living cell
a virus
The fact that a fungus is called imperfect means that a mode of sexual reproduction has not been discovered. Because we do not know about an aspect of its life, our knowledge of it is imperfect.
Explain the difference between annual and perennial plants
Annual plants only live for one year, whereas perennials grow year after year
The hormones in plants that regulate the development over cells, altering the amount that they elongate.
Auxins
Name all four characteristics of all animals
cells are eukaryotic, cells lack cell walls, are multicellular organisms, and are heterotrophic
