Vedclass · Answer

(A) Thallophytes (primarily Algae) are characterized by a simple,undifferentiated plant body known as a thallus. They lack specialized vascular tissues ($Xylem$ and $Phloem$),which makes them non-vascular. They do not possess archegonia (female sex organs found in Bryophytes,Pteridophytes,and Gymnosperms),making them non-archegoniate. They lack a true root,stem,and leaf system,which makes them non-cormophytic. Since the Reason accurately explains the structural characteristics that define the Thallophytes mentioned in the Assertion,both are correct and the Reason is the correct explanation.

$A$ : Thallophytes are non-vascular,non-archegoniate and non-cormophytic plants.
$R$ : Thallophytes lack vascular bundles,archegonia and differentiated plant body.
