Magnoliopsida. Definition noun (plant taxonomy) A taxonomic class comprised of the dicotyledonous plants, according to the Takhtajan system and the Cronquist system of flowering plant classification Supplement The flowering plants (angiosperms) that make up the division Magnoliophyta may be grouped into two major plant groups: Dicotyledoneae (or Magnoliopsida) and Monocotyledonae (or Liliopsida).
Dicotyledon, or dicot, any member of the flowering plants that has a pair of leaves, or cotyledons, in the embryo of the seed. There are about 175,000 known species of dicots. Most common garden plants, shrubs and trees, and broad-leafed flowering plants such as magnolias and roses are dicots.

Magnoliophyta is basically divided into two main divisions: the Anthophyta commonly known as Angiospermae, and the Pinophyta, which is known as Gymnospermae. Magnoliophyta is compost of over 200,000 species, which are approximately made of two-third of the known land flora ref1. Related: Wild and cultivated species of guava

Flowers produce seeds that are not naked. The flowers also attract pollinating insects where they help in the transfer of pollen grains. This helps prevent the extinction of flowering plants and make them the mo...
Gymnosperms are non-flowering plants. Meaning: they do not produce flowers and their seeds are naked. The seeds are not coverd in an overy and the spermatozoids are motile.
Magnoliophyta is a phylum or division, and they the most dominant of all land plants both economically and ecologically.
Magnoliopsida is a class of flowering plants that produce a young plant or embryo with two cotyledons and net-veined leaves.

2 Classification of Angiospermae. The class Magnoliopsida (Angiospermae) includes 413 families referable to 55 orders with 273,000 species in ca. 14,000 genera (Mabberley 2008, the Plant List 2011). There is some disagreement about the actual number of taxa at the lower levels.
Dicotyledonous plants (Class Magnoliopsida) are thought to be the most primitive flowering plants. They are defined by several characteristics. Similar to gnetophytes, all dicots germinate producing two seed leaves, hence dicotyledons. All dicots have other similar characteristics.
Class Magnoliopsida (Dicotyledons) Embryo usually with two cotyledons, sometimes one, rarely with three or four. Cotyledons commonly with three vascular bundles. Leaves mostly petioled. Venation typically reticulate, either pinnate or palmate, and mostly not closed (with free vein endings). Leaf traces 1–3, seldom more.
May 3, 2017 · Class Magnoliopsida (dicots) Members of the Class Magnoliopsida are defined partly on the basis of the seed or seedling having two cotyledons, most obvious at germination. But the differences between dicots and monocots are many, and we will be able to recognize most flowering plants that we encounter as belonging to one or the other class ...
