It would, therefore, be a misconception to speak of tropism as of reflexes, since tropismsare reactions of the organism as a whole, while reflexes are reactions of isolated segments.
As might be expected of instincts, the feature of utility is more in evidence than in simpler tropisms because they have become of proportionately greater magnitude, but the same fundamental mechanism is apparently at bottom of both.
The tropisms in many cases become indistinguishable from reflex actions and these in turn grade up into the instincts of animals.
In higher animals, therefore, the tropisms where operative must act more or less through the agency of the nervous system instead of directly through the general protoplasm of the organism.
Even those among the Amblyopsidae which live in the open have the tropisms of the cave dweller.
These tropisms play an important rôle in animal behaviour.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "tropisms" in a variety of sentences. We hope that you will now be able to make sentences using this word.
