Basic Tissue Types in Plants
|
Meristematic Tissues
Dermal Tissues Vascular Tissues Ground Tissues |
|
|
Meristematic Tissues
|
The actively growing parts
|
|
|
Dermal Tissues
|
The tissues that cover the surface of the plant (epidermis)
|
|
|
Vascular Tissues
|
Xylem - The tissue involved in transport of water and nutrients (interior) AND Phloem - The tissue involved in transport of sugars.
|
|
|
Ground Tissues
|
The simple cells that make up the bul of the body of an herbaceous plant.
|
|
|
Parenchym Cell
|
The least specialized cell of the plant, capable of resuming division at any point in the life of the plant.
|
|
|
Typical plant cell features
|
a primary cell wall with an exterior middle lamella made of pectin
a plasma membrane cytoplasm a nucleus ribosomes chloroplast and other plastids mitochondria plasmadesmata interconnections between the cells an internal membrane system consisting of the endoplasmic reticulum and Golgi bodies an enormous central cacuole that takes up the bulk of the cell volume |
|
|
Collenchyma cells
|
similar to parenchyma cells with unusually thick primary cell walls in the corner of the cell. They provide flexible support to herbaceous tissue of plants. Strings of celery are comprised of collenchyma cells
|
|
|
Sclerenchyma
|
Long thin fibers or short and fat sclereids. Have thick walls made of lignin (a strong polymer that gives wood its strength, similar to plastic) and are dead at maturity.
|
|
|
Plant organs
|
group of tissues with common functions
|
|
|
Angiosperms
|
Flowering plants
|
|
|
Monocots
|
One cotyledon of seed leaf,
Leaf shape strap-like, Venation pattern parallel Flowers in threes, Fibrous roots, Unable to produce secondary or woody growth |
|
|
Dicots
|
Two cotyledons or seed leaves
Leaf shape broad venation net-like Flowers in fours or fives Tap roots Able to produce secondary or woody growth |
|
|
Roots
|
A central vascular cylinder, and lateral roots that emerge from the inside and tend to occur in rows
|
