Abstract
(100 - 200 words; 1 or 2 sentences per section)
summary of
purpose
To determine if the assortment of
Armadillidium vulgare
is random
or not in response to phototaxis and hydrotaxis.
methods/techniques
Two petri dishes and were fastened for each taxis experiment. For
phototaxis, one dish excluded light and was attached with a dish that let light through. In
the hydrotaxis experiment, a circle was cut out of a paper towel to the diameter of the
bottom of the petri dish. After it was placed it in the dish, the towel was moistened.
numbers recorded
41 wet, 29 dry & 51 dark, 19 light

Intro
(at least one citation per statement of not common knowledge)
purpose/summary
In this paper I report evidence to determine if
Armadillidium vulgare
assorts randomly in response to phototaxis and hydotaxis. Many organisms have the
ability to recognize light, moisture, or both to guide themselves to locations within the
environment.
def/background
taxis
a motion or orientation of a cell, organism, or part in response
toward or away from an external stimulus.
phototaxis
the bodily movement of a motile organism in response to
light, either positively toward or negatively away from the source of light.
hydrotaxis
positive or negative response toward water
kinesis
an undirected movement of an organism involving a change in
activity caused by an external stimulus.
isopods
are an order of crustaceans that include both marine and terrestrial
creatures, and characterized by a cephalon.
