Types of Tissues

Tissues are groups of cells with a common origin.
Tissues are classified structurally into simple (one cell type) and complex (multiple cell types, like xylem and phloem).
Tissues are also classified functionally into meristematic (dividing cells) and permanent (developed cells).
Meristematic cells are living and have the ability to divide and form new cells.
Permanent tissues are living or non-living, with specialized structure to perform specific functions.
Apical meristem is the growing tip of the stem.

Plant Tissues (Diagrammed)

Different meristems (ground, procambium, and protoderm) give rise to different permanent tissues (primary xylem, primary phloem, ground tissue, and epidermis).
Secondary tissues (secondary xylem, secondary phloem, and periderm) develop from the vascular cambium.

Vascular Cambium

The vascular cambium is a lateral meristem that makes secondary vascular tissues.
It is formed of fusiform and ray initials.
Fusiform initials are elongated and produce the axial system of secondary vascular tissues.
Ray initials are isodiametric and form the parenchyma rays.
The cambial zone is composed of axial and ray systems, with a single layer of cambial initials.
Cambium cells divide either periclinally (producing new xylem or phloem cells) or anticlinally (increasing cambium diameter).
Vascular cambium can be storied (stratified) or non-storied.

Ray Initials

Ray initials divide periclinally, forming radial files of cells (parenchyma) towards the outside (secondary phloem) and inside (secondary xylem).
Ray initials can also divide anticlinally in plants with biseriate or multiseriate rays.
Vascular rays (ray parenchyma) are created from ray initials.
