Angiosperm Life Cycle Flowering plants are termed angiosperms. The flowering plants are the most dominant vascular plants that are found all around the world. What are Angiosperms? Phanerogams or spermatophytes are a plant division that comprises plants that bear seeds. This includes the gymnosperms as well as the angiosperms. Angiosperms are a plant group with flowers that produce seeds enclosed within a carpel. In other words, these are flowering plants that produce seeds within a fruit. Whereas gymnosperms are a plant group comprising seed-bearing plants with seeds unprotected by a fruit. Examples — conifers, cycads, etc. Examples of angiosperms — Roses, lilies, eggplant, tomato, rice, wheat, mango, etc. These plants typically have well-differentiated bodies with fully developed shoot and root systems. They can survive in various habitats. Angiosperms — Taxonomy The taxonomy of angiosperms is based on several primitive and advanced characteristics proposed by many systematists like Linnaeus and Takhtajan. Their ideas established different principles in taxonomy which are now helping us to understand the concept of angiosperms’ phylogeny.

Kingdom Plantae Division Spermatophyta Infradivision Angiosperms Angiosperms were formerly termed Magnoliophyta. This division of flowering plants is further divided into 2 classes: 1. Liliopsida (Monocotyledons) ~ Banana 2. Magnoliopsida (Dicotyledons) — Sunflower
