PRAXIS 5236 EXAM QUESTIONS WITH
CORRECT ANSWERS
Vascular Plant - Correct Answers -has true leaves, stems, roots that contain xylem and
phloem
Nonvascular Plants - Correct Answers -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 - Correct Answers -Animals (such as birds or mammals) that can regulate
their body temperature regardless of the environments.
ectotherms - Correct Answers -An animals that warms itself mainly by absorbing heat
from its surroundings.
Xylem - Correct Answers -vascular tissue that carries water upward from the roots to
every part of a plant.
cohesion-tension theory - Correct Answers -theory that explains how the physical
properties of water allow it to move through the xylem of plants
Starch - Correct Answers -A storage polysaccharide in plants consisting entirely of
glucose.
Altruism - Correct Answers -unselfish concern for the welfare of others
Primary succession - Correct Answers -An ecological succession that begins in an area
where no biotic community previously existed
Secondary succession - Correct Answers -Succession following a disturbance that
destroys a community without destroying the soil
Phloem - Correct Answers -Living vascular tissue that carries sugar and organic
substances throughout a plant
Phloem, Food
Convergent Evolution - Correct Answers -Process by which unrelated organisms
independently evolve similarities when adapting to similar environments.
, Speciation - Correct Answers -When organisms reach a point at which two new species
are formed
divergent evolution - Correct Answers -The evolutionary process in which organisms of
one species become increasingly dissimilar in appearance .
interspecific competition - Correct Answers -Competition between individuals of
difference species for the same limited recourses.
Angiosperms - Correct Answers -A flowering plant which forms seeds inside a
protective chamber called an ovary.
gymnosperms - Correct Answers -A plant that produces seeds that are exposed rather
than seeds enclosed in fruits
Parenchyma - Correct Answers -Fundamental tissue composed of thin-walled living
cells that function in photosynthesis and storage, tissue repair
Collenchyma - Correct Answers -Made of collenchyma cells. provides support in roots
stems and petrioles.
Sclerenchyma - Correct Answers -made of sclereid cells. provides rigid structure and
protection .
interspecific competition - Correct Answers -competition between members of different
species
intraspecific competition - Correct Answers -Competition among members of the same
species
Ecological succession - Correct Answers -series of gradual changes that occur in a
community following a disturbance
Primary succession vs secondary succession - Correct Answers -Primary: 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 - Correct Answers -a process which separates the parts of a solution
with special paper and a solvent.
Electrophoresis - Correct Answers -A process where DNA fragments are separated
according to size using electrical charges
Cell theory - Correct Answers -all 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
