a group of cells performing similar function
tissues
what are two types of tissues
> Meristematic Tissue
Permanent tissue
also known as “embryonic tissue”. responsible for the production of more cells
Meristematic Tissue
The assume into various shapes and sizes as they develop and mature
Permanent tissue
Under meristematic tissue, we have:
Apical Meristem
Lateral Meristem
Intercalary Meristem
found near the tips of the root, increase in length.
Produces new cells and primary tissue
Apical Meristem
produces new tissues.
Increase in girth of roots and stems
Lateral Meristem
the same with apical meristem, it also increases in length.
Develop at intervals where the tissues add to the length of the stem
Intercalary Meristem
Under Permanent Tissue there is:
Complex and Simple tissue
_____ are composed of multiple tissue (Vascular and Dermal Tissue)
Complex Tissue
____Are composed of only one type of cell (Ground Tissue)
Simple Tissue
Under Apical Meristem, we have:
Protoderm
Ground Meristem
Procambium
found in the outermost layer of cells
Protoderm
primary tissue of a growing tip of a stem or root
Ground meristem
forms cambium and primary vascular tissues
procambium
Under Lateral meristem we have
Vascular cambium
Cork cambium
Produces secondary tissue for support and conduction
Vascular cambium
Found outside the vascular cambium
Cork cambium
Under “ground tissue” we have
Parenchyma
Collenchyma
Sclerenchyma
primary component of ground tissue
Parenchyma
provides support in soft, non-woody plants
Collenchyma
provides support and strengthen non-extending regions of plants
Sclerenchyma
ground tissue that forms usually between dermal and vascular tissue
Cortex
ground tissue that usually forms inside the vascular tissue
Pith
chloroplast containing cells that specializes on photosynthesis
Chlorenchyma
tissues with extensive connected air/intracellular spaces
Aerenchyma
what happens when parenchyma and collenchyma come together
absorbs large amount of water
provides protection and prevents water loss
Dermal Tissue
____ is superficial layer of cells
Epidermis
replaces the epidermis in stems and roots of older woody plants
Periderm
transports water, minerals and food
Vascular Tissue
xylem conducts _______ and minerals
water
phloem distributes ______ and mineral
sugar
types of tracheary elements
Spiral
Scalariform
Pitted type
Reticulate
Annular
