| Tissue : Group of cells similar or dissimilar type and origin working together to perform a common function | |
| Meristematic | Permanent |
| Retains the power of division Eg: Apical, Lateral Intercalary | Lost the power of division A. Simple: Parenchyma, collenchyma, aerenchyma b. Complex: xylem and phloem |

Basics terms of anatomy:
1. Eustele: Arrangement of vascular bundles like concentric ring
2. Atactostele: scattered
3. Conjoint: Xylem and phloem in same radius
4. Radial: Xylem and phloem in different radius
5. Exarch: Protoxylem toward periphery and meta xylem toward center
6. Endarch: Metaxylem toward periphery
Distinguishing features:
Root: Epiblema, radial, exarch
Difference between Dicot and Monocot stem
|
| Dicot | Monocot |
| Epidermis | Hair present | Usually absent |
| Stomata | Kidney shaped | Dumbell shaped |
| Hypodermis | Collenchymatous | Sclerenchymatous |
| Ground tissue | Heterogenous: differentiated into Cortex, pericycle, pith | Homogenous: undifferentiated |
| Vascular bundle | 1. Eustele: concentric ring like 2. Few 3. Wedge shaped 4. Conjoint collateral open | 1. Atactostele: scattered 2. many 3. Oval shaped 4. conjoint collateral closed ie. Cambium absent |
| Bundle sheath, Water cavity, Secondary growth | Absent | Present |
| pith | distinct | Not distint |
