Vascular Plant - answer has true leaves, stems, roots that contain xylem and phloem
Nonvascular Plants - answer lack true leaves, stems, and roots and do not have any
true vascular tissue but instead rely on diffusion and osmosis to transport most
matersals or recourses needed to survive
endotherms - answerAnimals (such as birds or mammals) that can regulate their body
temperature regardless of the environments.
ectotherms - answerAn animals that warms itself mainly by absorbing heat from its
surroundings.
Xylem - answervascular tissue that carries water upward from the roots to every part of
a plant.
Phloem - answerLiving vascular tissue that carries sugar and organic substances
throughout a plant
Phloem, Food
Convergent Evolution - answerProcess by which unrelated organisms independently
evolve similarities when adapting to similar environments.
Speciation - answerWhen organisms reach a point at which two new species are
formed
divergent evolution - answerThe evolutionary process in which organisms of one
species become increasingly dissimilar in appearance .
interspecific competition - answerCompetition between individuals of difference species
for the same limited recourses.
Angiosperms - answerA flowering plant which forms seeds inside a protective chamber
called an ovary.
gymnosperms - answerA plant that produces seeds that are exposed rather than seeds
enclosed in fruits
Parenchyma - answerFundamental tissue composed of thin-walled living cells that
function in photosynthesis and storage, tissue repair
, Collenchyma - answerMade of collenchyma cells. provides support in roots stems and
petrioles.
Sclerenchyma - answermade of sclereid cells. provides rigid structure and protection .
interspecific competition - answercompetition between members of different species
intraspecific competition - answerCompetition among members of the same species
Ecological succession - answerseries of gradual changes that occur in a community
following a disturbance
Primary succession vs secondary succession - answerPrimary: An ecological
succession that begins in an area where no biotic community previously existed,
Secondary: Succession following a disturbance that destroys a community without
destroying the soil
Chromotography - answera process which separates the parts of a solution with special
paper and a solvent.
Electrophoresis - answerA process where DNA fragments are separated according to
size using electrical charges
Cell theory - answerall living things are composed of cells, cells are the basic units of
structure and function in living things, new cells are produced from existing cells
Germ Theory of Disease - answeridea that infectious diseases are caused by
microorganisms
Waste Disposal Methods - answerLandfill, incineration, sewege
Energy Production - answerCoal fired power plants, gasoline, nuclear power plants,
hydropower, wind and solar power, geothermal power
Organic Molecule - answerA molecule that contains carbon and hydrogen
Covalent Bond - answerA chemical bond that involves sharing a pair of electrons
between atoms in a molecule
Four classes of micromolecules - answerCarbohydrates, nucleic acids, proteins, and
lipids.
First law of thermodynamics states that the - answerthe total energy of the universe is
constant
