|Bark||Includes secondary phloem and periderm|
Phellogen (cork cambium)
Phelloderm (secondary cortex)
|Bulliform cells||Modified adaxial epidermal cells in grasses|
|Parenchyma||Isodiametric, thin cellulosic cell wall.
Photosynthesis, storage and secretion
|Collenchyma||Present below epidermis in dicotyledonous plants.
No intercellular spaces, thickened corner due to cellulose, hemicellulose and pectin deposition.
|Sclerids||Present in fruit walls of nuts, pulp of fruits (guava, pear, sapota), seed coat of legumes and tea leaves|
|Xylem vessels||Multicellular, absent in gymnosperms|
|Xylem tracheids||Unicellular, elongated with tapering ends and lignified wall|
|Endarch primary xylem||Stem|
|Exarch primary xylem||Root|
|Ray parenchymatous cells||Radial conduction of water|
|Phloem of gymnosperms||Lack sieve tubes and companion cells.
Contain albuminous and sieve cells.
|Companion cells||Specialised parenchymatous cells and help in maintaining pressure gradient in sieve tubes|
|Phloem parenchyma||Plasmodesmatal connections between the cells.
Absent in most of the monocots
|Root hairs||Unicellular elongations of epidermal cell|
|Trichomes||Epidermal hairs on the stem|
|Dicot root||Vascular bundles- Radial, diarch to tetrarch, small pith|
|Monocot root||Vascular bundles- Radial, polyarch large pith.
No secondary growth.
|Dicot stem||Hypodermis- Collenchymatous
Endodermis- Starch sheath
Pericycle- Semi-lunar patches of sclerenchyma
Vascular bundles- Conjoint, collateral, open and arranged in a ring
|Monocot stem||Hypodermis- Sclerenchymatous
Bundle sheath- Surrounds each vascular bundle
Vascular bundles- Conjoint, collateral, closed (no cambium) and scattered
|Dicot leaf||Dorsiventral, more stomata on abaxial surface.
Mesophyll- palisade parenchyma (towards adaxial) and spongy parenchyma (towards abaxial).
Presence of air cavity.
|Monocot leaf||Isobilateral, stomata equally distributed on both the surfaces.
Mesophyll- not differentiated into palisade and spongy parenchyma.
Presence of bulliform cells.
|Casparian strips||Made up of suberin and present on the radial and tangential walls of endodermal cells of roots.|
Initiation of lateral roots and vascular cambium during secondary growth.
|Spring wood||Early wood, lighter, lower density and have vessels with wider cavities|
|Autumn wood||Late wood, darker, denser and have vessels with narrow cavities|
|Lenticels||Lens shaped openings in the stem of woody trees.
Help in gaseous exchange.
