Re: What behavior is exhibited in Paramecium caudatum from action potentials?

Hello there!

Paramecium caudatum shows favorable behavior towards slightly acidic 
solution and unfavorable behavior towards too much acidic solution and 
salty solution. 

So it will show unfavorable behavior towards KCl solution by spinning and 
favorable behavior towards the acidic solution. The spinning is called 
swinging reaction.

I am summarizing the effects of different things on Paramecium caudatum.

Thermotaxis  
Extremes 10 C and 35 C
25 c is optimum.

Phototaxis
Diffused light is optimum.

Thermotaxis
Moves by trial and error method.

Chemotaxis
I talked about this earlier.

and so on...

The main cause for not entering a salt solution is that Osmosis might 
occur in a salt solution. Since the salt solution is hypertonic, the 
liquid in the P. caudatum would come out causing it to shrink and decay. 
Thus it avoides even slight salt solution.
The main types of responses are Trail and Error Method and spinning. P. 
Caudatum shows trial and error method when it strikes an object.
