Anatomy of Flowering Plants

Axillary bud Shoot apical meristem
Intrafascicular cambium Primary lateral meristem
Interfascicular cambium, cork cambium Secondary lateral meristem
Bark Includes secondary phloem and periderm
Periderm Phellem (cork)

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.
Pericycle Parenchymatous.

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.
