Assertion: Antheorozoids of Funaria show chemotrophic movement.
Reason: This is a paratonic movement of locomotion.


 Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Chemotactic movement is the movement of an organism towards or away from the chemical stimulus whereas Chemotropic movement is growth of an organism or its part in response to the chemical stimulus.
Antherozoids of Funaria move toward the archegonium in response to the sugars secreted by the Funaria showing chemotropic movement.
This is referred as paratonic movement since it occurs in response to an external stimulus i.e. chemicals are secreted from the archegonium.
