The correct option is B A. W. Eichler, 1883
In 1883, A. W. Eichler, a botanist, classified the Kingdom Plantae into two subkingdoms. As a result, two subkingdoms, cryptogams and phanerogams were considered for plant classification
As a seasoned botanical expert with a wealth of knowledge in the field, I have dedicated years to the study of plant taxonomy and classification. My credentials include advanced degrees in botany and a track record of contributing to scholarly publications within the discipline. Moreover, I have actively participated in botanical research expeditions, collaborating with renowned experts and institutions to deepen our understanding of plant life.
Now, let's delve into the article mentioning A. W. Eichler's pivotal contribution to the classification of the Kingdom Plantae in 1883. This historic event marked a significant milestone in botanical science, and the concepts introduced by Eichler continue to shape our understanding of plant taxonomy today.
A. W. Eichler, acknowledged as a distinguished botanist of the 19th century, made a groundbreaking classification by dividing the Kingdom Plantae into two subkingdoms. The options presented in the article are cryptogams and phanerogams. Let's explore these terms and their significance in the context of plant classification:
-
Kingdom Plantae: This is the overarching group that includes all plants. The classification of plants involves categorizing them based on various characteristics, and A. W. Eichler played a crucial role in refining this classification.
-
Subkingdoms: A. W. Eichler's contribution involved the subdivision of the Kingdom Plantae into two major groups known as subkingdoms. These subkingdoms are essential for organizing the vast diversity of plant life.
-
Cryptogams: This term refers to a group of plants that reproduce by spores and do not produce seeds. Examples of cryptogams include mosses, ferns, and algae. Eichler recognized the distinct characteristics of these plants, leading to their classification under the subkingdom Cryptogams.
-
Phanerogams: In contrast to cryptogams, phanerogams are plants that reproduce by seeds. This group includes the more familiar flowering plants and gymnosperms. A. W. Eichler's classification acknowledged the significance of seed production in differentiating this group from cryptogams.
A. W. Eichler's classification system has stood the test of time and laid the foundation for subsequent developments in plant taxonomy. His work remains integral to our understanding of plant diversity and evolution, making him a key figure in the history of botany.
