Vedclass · Answer

(C) In $Funaria$ (a moss),the archegonium secretes sucrose at the tip of the neck to attract the male gametes (antherozoids). This movement of male gametes towards the chemical stimulus (sucrose) is known as chemotactic movement,not chemotropic movement. Chemotropism refers to the growth of a plant part in response to a chemical stimulus,whereas chemotaxis refers to the movement of a whole organism or cell (like a motile gamete) in response to a chemical stimulus. Therefore,the Assertion is correct,but the Reason is incorrect because it uses the wrong terminology.

$A$: $Funaria$ archegonium has maximum concentration of sucrose at the tip of the neck.
$R$: Male gametes show chemotropic movement.
