What is the difference between Zea mays and canna stem? Hypodermis is present and consists of 2 to 3 layers of sclerenchyma. No such hypodermis is seen. However, 2 to 3 layers compactly arranged parenchyma are found and this may be considered as hypodermis.

Stems of Monocotyledon plants exhibit a number of variations in their anatomy from that of dicotyledon stems. The following distinct differences are marked in monocot stem.
What is the difference between Tridax and Cucurbita stem? Each vascular bundles is conjoint, collateral and with one patch of cambium and phloem. Each vascular bundle is conjoint, bicollateral with two patches of cambium and phloem.
Distinct features of Internal structure of dicotyledon stem. The anatomy of a typical dicot stem shows clear distinction into different regions. The primary structure shows (i) epidermis, (ii) hypodermis, (iii) cortex which is generally narrow, (iv)Endodermis, (v) Pericycle, (vi)stele and (vii) pith.
The difference between Dicot Stem Anatomy and Monocot Stem Anatomy are dicot stem the epidermal multicellular stem hairs are present whereas in monocot stem usually stem hair are absent.
Secondary growth may be defined as an increase in thickness due to the formation of secondary tissues. The secondary growth in dicotstem occurs by the activity of cambium at the stellar region and cork cambium at the extra stellar region.
The difference between Dicot Stem and Dicot Root are :- in the former the outermost layer is called epidermis; the outer wall is covered with thick cuticle. The epidermis contains multicellular hairs and stomata here and there whereas in the later the outermost layer is called epiblema. It consists of thin-walled cells and containing intercellular hairs. Stomata and cuticle are absent.
The difference between Vascular Bundles in Monocot and Dicot Stem are in Dicot Stem vascular bundles are arranged in ring whereas in Monocot stem vascular bundles are scattered in ground tissues.
Transverse section of a monocot stem shows the following regions (Example. Maize): Epidermis- It consists of a single layer of cells at the outermost region of the stem. The outer surface is covered by a thick cuticle.Epidermis contains stomata here and there.
