Question

This is considered a demerit of the 'Engler and Prantl' in the system of classification
A. Gymnosperms are placed between monocotyledons and dicotyledons
B. Dicotyledons are placed after monocotyledons
C. Dicotyledons are placed before monocotyledons
D. Gymnosperms are placed among Dicotyledons

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of Engler and Prantl's classification.
After Darwin's Theory of Evolution was accepted, Engler and Prantl introduced their groundbreaking theory, which is based on the idea that blooming plants lacking perianth are evolutionary primitives.

Complete answer:
Achlamydeous flowers are treated in an archaic way by this system, which may indicate that they are a derived condition. Unisexual families are more developed than bisexual households, according to new evidence.
Between the more developed orders, Pandanales and Glumiflorae is the primordial order, Heloise.
It is forbidden to include naturally unrelated taxa in an assemblage.
In many instances, the system is not strictly phylogenetic.
In the system, monocotyledons were placed before dicotyledons, which run counter to accepted evolutionary theories that were later modified. The way achlamydeous flowers are treated in this system may be derived.
Therefore, a demerit of the 'Engler and Prantl' in the system of classification is “Dicotyledons are placed after monocotyledons”

Option ‘B’ is correct

Note:
The entire Engler and Prantl system has fourteen primary divisions. The bryophytes, fungus, Pteridophytes, and algae were among the original thirteen divisions. The Gymnosperms and the Angiosperms were both included in the fourteenth division, Embryophyta Sighonogama.
