List the 3 Meristem or Meristematic Tissues
Apical Meristems, Lateral Meristems, and Intercalary Meristems
region of cells capable of division and growth in the root and shoot tips in plants. give rise to the primary plant body and are responsible for the extension of the roots and shoots. responsible for length
Apical Meristems
young, undifferentiated tissue of a root or stem that eventually develops into epidermis. It gives rise to skin coverings.
Protoderm
gives rise to ground tissue and cortex pith, a group of tissues with generalized functions such as photosynthesis, storage, and support.
Ground Meristem
gives rise to the vascular tissue, which functions in transport.
Procambium
Known as primary tissues
Apical Meristem
responsible for secondary growth, or increase in stem girth and thickness.
Lateral Meristems
also known as secondary tissues
Lateral Meristems
Often referred to simply as cambium,
Vascular cambium
A thin cylinder or irregular arrangement of meristematic cells that runs the length of roots and stems of woody plants. It lies outside the vascular cambium just inside the outer bark which it produces.
Cork Cambium
the single-cell layer of cells that produces cork and phelloderm cells.promote growth of secondary xylem and phloem
Cork cambium
Simple Tissues
Parenchyma, Collenchyma, Sclerenchyma
Complex Tissues
Xylem, Phloem, Epidermis, Periderm, Secretory Cells and Tissues
A plant cell that is relatively unspecialized, is thin walled, may contain chlorophyll and is typically rather loosely packed. It is composed of parenchyma cells which are the most abundant cell types and are found in almost all major parts of higher plants.
Parenchyma tissue
provide mechanical support for growing plants
Collenchyma cells
composed of dead cells that have heavily thickened walls containing lignin and a high cellulose content (60%–80%), and serves the function of providing structural support in plants.
Sclerenchyma tissue
conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support.
Xylem
transport and distribution of sugars produced by the photosynthesis.
Phloem
to form the cuticle, forms a protective layer covering all plant organs that consist primarily of parenchyma and parenchymalike cells.
Epidermis
comprises the outer bark of woody plants consists mostly of cork cells but contains pockets of parenchyma-like cells.
Periderm
