What is the response that the woodlice made?
Table of Contents
reflex response
Woodlice do move more quickly in dry conditions, and more slowly in damp. This is the reflex response that results in their accumulation in damp areas.
What would a woodlouse prefer answer key?
Because woodlice have very simple eyesight, Nora thought that maybe they use dark and light colors to decide where to go. They might choose to move towards darker colors and away from lighter colors to prevent ending up above ground where predators can easily find them.
How do woodlice respond to stimuli?
If you use a lamp to establish a light/ dark gradient, the woodlice may in fact be responding to the heat of the lamp. A directional response to stimuli is called a ‘taxis’ (for example phototaxis, or a phototactic response).
Why do woodlice prefer dark and humid conditions?
A behavioural adaptation is an action an animal takes that increases its chances of survival. Woodlice move faster in dry areas, and more slowly in humid environments. This behaviour results in woodlice spending more time in more humid environments and prevents their body from drying out.
How does kinesis occur in woodlice?
In kinesis, an organism changes its movement in a non-directional way—e.g., speeding up or slowing down—in response to a cue. For example, woodlice move faster in response to temperatures that are higher or lower than their preferred range.
Why do woodlice not like bright light?
Woodlice have a negative photokinesis- they move faster as the light stimulus increases. This has great survival value because bright places tend to be drier and dark places tend to be damper.
Do woodlice prefer dark or light?
HYPOTHESIS Woodlice prefer dark, damp and warm surroundings to light, dry and cold environments, by setting up a choice chamber with all of the available conditions within, I will determine that woodlice do prefer a wetter, darker environment to a lighter, drier one.
Which would a woodlice prefer?
Do woodlice have gills?
While most crustaceans live in water, woodlice live on land but breathe through gills like fish. Their gills need to be covered with a thin layer of water to work well, so they prefer to live in places with a lot of moisture. These creatures are found in cool, damp areas, such as under fallen leaves in flowerbeds.
What is a positive taxis?
A positive taxis is one in which the organism or a cell moves towards the source of stimulation (attraction). A negative taxis is when the organism or a cell moves away from the source of stimulation (repulsion).
What is the difference between kinesis and taxis?
Kinesis and taxis are both types of movement. Kinesis is undirected, random movement, while taxis is directed in relation to a given stimulus.
Why do woodlice clump together?
Woodlice tend to move quicker in dry places than damp places. You may also see them ‘clump’ together. This helps them to reduce their water loss as it reduces the surface area that is in the open air, as by less air passing their outer layer, less water is lost in that way.
