Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In artificial system of classification, only a few characters of the plants are being considered, for example, the grouping of plants into shrubs and trees or the sexual system of Linnaeus based on number of stamens and styles. The best known artificial system is of Linnaeus published in 1735. In natural system of classification, all the important characters of the plant are being considered, and the plants are classified according to their related affinities. Bentham and Hooker gave the natural system of classification. Phylogeny system in phylogenetic system of classification the plants are classified according to their evolutionary and genetic affinities. This system of classification was proposed by Engler in $1886$, Hutchinson in $1926$.

Concepts Used:
Plant Kingdom
The Plant Kingdom comprises all the plants that have some shared characteristics. These are bacteria (prokaryotes), photosynthetic plants, fungi, and several non-photosynthetic plants.

Several features of Kingdom Plantae are as follows:
- They are stationary. They are static and usually remain in one place only.
- They have branches that expanded and green leaves due to the presence of chlorophyll.
- They are an autotrophic mode of nutrition that simply means they prepare their food with the help of water, sunlight and carbon dioxide. It is further known as self-nutrition.
- They indulge in photosynthesis during the day and therefore more carbon dioxide is needed during the day and at night it is released.
- They secure their food in the form of starch-like algae.
- They have an inelastic wall around their cell known as a cell wall comprised of cellulose.
- There is an absence of the nervous system and excretory system.
- Reproduction is entirely dependent on air, insects and water. Asexual and vegetative method of reproduction is noticed or detected.
- The non-photosynthetic plants acquire their food through parasitism, i.e through their host like Indian pipe.
