Missing

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
