Classification of Angiosperms
Angiosperms are divided into two subgroups—dicotyledonous (dicots) and monocotyledonous (monocots).
Monocotyledons
- There is only one cotyledon on each seed.
- The leaves have parallel veins and are simple.
- This group includes accidental roots.
- There are three parts in each floral whorl.
- It has numerous, closed vascular bundles.
- Bananas, sugarcane, flowers, etc. are a few examples
Dicotyledons
- These plants produce seeds with two cotyledons.
- Instead of adventitious roots, they have tap roots.
- The venation on the leaves is reticulated.
- The vascular bundles are arranged in rings, and the flowers are either tetramerous or pentamerous.
- Take grapes, sunflowers, tomatoes, etc. as examples.
Angiosperms
Angiosperms come under the classification of Plant Kingdom. Kingdom Plantae incorporates every one of the plants. They are eukaryotic, multicellular, and autotrophic life forms. The plant cell contains an unbending cell wall. Plants have chloroplast and chlorophyll shade, which is expected for photosynthesis. All eukaryotic, multicellular plants that use photosynthesis to create their nourishment belong to the kingdom Plantae.
Cell walls in plants are stiff and comprised of cellulose and pectin. They include photosynthesis-promoting organelles like chloroplasts and chlorophyll. These do not move. They are capable of both sexual and asexual reproduction. Few plants, like the pitcher plant, are unable to make their own food and obtain sustenance by feeding on insects. They help to keep the ecological equilibrium. Global warming is a result of a decline in plant diversity. They replicate abiogenically by vegetative engendering or physically. Different techniques are used by the species in the Kingdom Plantae to reproduce. Some species use sexual reproduction, while others use asexual methods. In the traditional system of classification, the plant kingdom is divided into two subdivisions- cryptogams and phanerogams. Seed plants are divided into two groups, gymnosperms, and angiosperms.
