Can you explain this answer?

Question

Answer

Answer

The earliest system of classification used only the gross superficial morphological characters such as colour, number , habitat and etc  into consideration. They were generally based on the vegetative characters or on the androecium structure ( the system which was given by Linnaeus) .... such systems of classification were artificial because they separated the closely related species . The artificial system of classification gave an equal weightage to vegetative and sexual characteristics and this is not acceptable as we are familiar that these characters are more easily affected by the environmental conditions.

Answer

Explanation:

The system of plant classification proposed by Carolus Linnaeus was considered artificial because it was based on similarities and differences in floral and other morphological characters only. Here is a detailed explanation:

Morphological Characters:
- Linnaeus classified plants primarily based on their morphological characters, such as the structure of flowers, fruits, leaves, and stems.
- He developed a binomial nomenclature system, where each plant species was given a unique two-part name based on its genus and species.
- This system allowed for easy identification and organization of plants, but it did not consider their evolutionary relationships.

Floral Characters:
- Linnaeus placed a strong emphasis on floral characters, as these were often readily observable and easily distinguishable.
- He classified plants based on the number, arrangement, and structure of floral parts, such as petals, sepals, stamens, and pistils.
- This approach allowed for the categorization of plants into different classes, orders, families, and genera, but it did not take into account other important characteristics, such as their genetic makeup or evolutionary history.

Limited Scope:
- The Linnaean system of classification focused primarily on the external appearance of plants and did not consider their physiological or biochemical characteristics.
- This limited scope of classification failed to reflect the true evolutionary relationships between plants.
- For example, some plants with similar floral characteristics may belong to different families or genera due to differences in their evolutionary history or genetic makeup.

Artificial Classification:
- The artificial system of classification proposed by Linnaeus was based solely on easily observable morphological characters.
- It did not incorporate the concept of evolutionary relationships or phylogeny, which is crucial for understanding the evolutionary history and genetic relatedness between different plant species.
- The Linnaean classification system was later replaced by the more comprehensive and natural system of classification, which considers evolutionary relationships and genetic similarities.

Conclusion:
The Linnaean system of plant classification was considered artificial because it relied solely on floral and other morphological characters, without considering the evolutionary relationships or genetic similarities between different plant species.

Answer

The system of classification in which one or very few character are considerd as the key feature of classication called artificial system.
this system of classification nvr throws light on relationship of plants with one another.
BASIS OF LINNAEUS'S ARTIFICIAL SYSTEM
linnaeous claasifies all flowering plants under 24 classes on basis of floral character which includes:-
i. No. of stamens presnt in flwr.

ii. insertion of florl parts into the thallmus.

iii. arreangement adhesion & distribution of stamen.

iv. nature of anther & filaments & their arrangement.
