TISSUE
In Plant Morphology, what are the two systems?
Shoot and Root Systems
Name the two root systems
Taproot and Fibrous Roots
Covered by water-conserving cuticle.
Epidemis
Arrangement of leaves on the stem
Phyllotaxy
The upward push of xylem sap
Root pressure
What are the Three Basic Tissue Types
Dermal, Ground, Vascular
A layer of cells just inside the endodermis of the root. Gives rise to lateral roots.
Pericyle
What are the two vascular tissues?
Xylem and Phloem
Large, thin-walled cells located at the upper epidermis; helps reduce water loss
Bulliform cells
It allows unbroken columns of water to be pulled up narrow vessels and tracheids of stem xylem.
Cohesion of water molecules
What are the three Ground Tissues
Parenchyma, Collenchyma, Sclerenchyma
A specialized aerial root produced by certain trees living in swampy habitats. May facilitate gas exchange between the atmosphere and submerged roots.
PNEUMATOPHORE
Name the three primary meristems
Protoderm, Ground Meristem, and Procambium
Plants adapted to a freshwater habitat
Hydrophytes
Name the two structures for long distance transport of water and dissolved nutrients
Vessel elements and tracheids.
Name three structures found in the epidemis
Stomates, Trichomes, Root hairs
A band of waterproof material around the radial and transverse cells of the endodermis. Ensures that water and minerals enter the xylem only by passing through the endodermal cells.
CASPARIAN STRIP
Name three structures present in stems that are not found in roots.
Name three structures found commonly in monocot leaves.
Sheath, Ligule, and Auricle
Name the three Short-Distance Transport
Simple diffusion/osmosis, Symplast, Apoplast
Name the six plant organs
Root, Stem, Leaf, Flower, Fruit, Seed
An extension of an epidermal cell of a root that increases absorptive capacity of the root
Root Hairs
What are the three main functions of the stem?
Support, Conduct, and Produce new living tissues.
Name four factors affecting stomatal movement
Light, Moisture, Temperature, CO2 concentration
What theory/hypothesis explains the transport of water and food within plants.
Tension- Cohesion Theory and Pressure-Flow Hypothesis
