Flowering plants or angiosperms are divided into two large groups. Monocotyledons or monocots have one seed lobe, which is often modified to absorb stored nutrients from the seed so never emerges from the seed or becomes photosynthetic. Dicotyledons or dicots have two cotyledons and often germinate to produce two leaf-like cotyledons.
They are a group of seed producing plants, which include Coniferophyta,Ginkgophyta,Cycadophyta and Gnetophyta. Angiosperms: Flowering plants approx. 300,000 They are divided into two main classes the monocotyledons and dicotyledons, produce seeds that are protected by fruits.
The spermatophytes were traditionally divided into angiosperms, or flowering plants, and gymnosperms, which includes the gnetophytes, cycads, [5] ginkgo, and conifers. Older morphological studies believed in a close relationship between the gnetophytes and the angiosperms, [ 6 ] in particular based on vessel elements .
The largest seed in the world is the coco de mer, [1] [2] the seed of a palm tree. [3] It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds).
The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided. The name refers to one of the typical characteristics of the group: namely, that the seed has two embryonic leaves or cotyledons. There are around 200,000 species within this ...
Image Credit: 123RF. Not all seeds sprout at the same rate. While environmental conditions may alter germination time (e.g., if the soil is too cold, tomato seeds may take longer to germinate ...
A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed] Dilleniales; superrosids consisting of Saxifragales and rosids (the APG IV system includes the Vitales in ...
