– Dicots = 2 cotyledons
This and This…

Seeds
DICOT: A – epicotyl, B – radicle, C – 2
cotyledons, D – seed coat
Monocot Seed
Stem
MONOCOT: 1- Epidermis, 2 – vascular
bundle/tissue 3- phloem, 4- xylem,
5 – parenchyma
Dicot Stem
A – epidermis, B – phloem, C – Xylem,
D- Sclerenchmya/collenchyma, E- parenchmya
