with a nucleus
Paramecium has sensitivity through specialized structures called trichocysts and cilia. Trichocysts can be discharged in response to physical or chemical stimuli, aiding in defense mechanisms. Cilia help the paramecium to detect and respond to changes in its environment, such as light intensity or the presence of food particles.
come from
Paramecium can respond to light by moving towards or away from it through a process called phototaxis. When exposed to light, Paramecium will swim towards the light source (positive phototaxis) or swim away from it (negative phototaxis) depending on the species and environmental conditions.
bacteria do not respond to changes in the surroundings
No, paramecium do not have a nervous system or pain receptors, so they do not experience pain like animals with more complex nervous systems. They respond to stimuli in their environment to survive and reproduce.
yes
Not typically. Barereceptors respond to touch and pressure. Atmospheric changes are too small to activate them.
a consumer will respond to the price changes in such a way that it could express its marginal utility
because it has a thick outer membrane called the pellicle
Yes of course. Mushrooms are living things and living things respond to changes. ♡♥
Yes they do.
