In turn, each order ex. In addition, the author Michael George Simpson gave the following proportionate composition of the two major groups in the angiosperms:.
Mathematical derivation indicates that the total number of species of angiosperms already described exceeds , exact calculation is , Certainly, the list is not finite, there are species that still wait to be discovered. The distinctive characteristics of plants belonging to these two groups of angiosperms are summarized in the table below.

Monocots, on the other hand, typically grow a fibrous root system, which is a dense network of roots that grows closer to the soil surface. The stem of a flower supports the leaves and flowers so that the plant can successfully perform photosynthesis and reproduction.
According to the Georgia Institute of Technology, stems contain two types of vascular tissue: xylem and phloem. The xylem tissue helps to support the stem and delivers water and nutrients from the roots to the rest of the plant.
Phloem transports the compounds produced during photosynthesis from the leaves to the rest of the plant. Both monocot and dicot stems have vascular bundles made up of xylem and phloem, but these tissues are arranged differently within the stem.
In a monocot stem, the vascular bundles are scattered and found in different locations in the stem, notes Wharton County Junior College. In dicot stems, the vascular bundles are found in a ring inside the stem. Another difference is that monocots only have one meristem at the tip of the stem. Most dicots , however, share a common pollen structure that differs from that of monocots and a minority of dicots ; this large subgroup of dicots is called eudicots.
A plant's pollen structure is what makes it a eudicot , but its seeds differ from those of monocots in the same way that the seeds of all dicots differ. How do you identify a monocot and dicot? How do you tell if a plant is a monocot or dicot?
