Plant Bio Final 1

soil layers with specific characteristics

a soil horizon rich with organic matter and decomposing litter

zone of leacing, may be dark in color

zone of deposition

parent rock

Nitrogen (N), Potassium (K), Calcium (Ca), Magnesium (Mg), Phosphorus (P), and Sulfur (S)

Sodium (Na), Iron (Fe), Manganese (Mn), Chlorine (Cl), Copper (Cu), Zinc (Zn), Boron (B), and Molybdenum (Mo)

roots that develop from the stem

a band of water resistant material in the radial walls of the endodermis

the innermost layer of cells of the cortex

roots that are adventitious from the stem and replace a prominent tap root.

roots that develop from the tap root.

a symbiotic association between the root and a fungus.

the outer most layer of cells of the vascular cylinder.

the principle site of cel division in the root tip.

adventitious roots that grow from the stem and help hold the plant erect. I think these are like corn and other such crops.

a group of cells that protect the root tip as it grows through the soil. It is also the site of gravity detection.

the xylem and phloem of the root.

layers of stem tissue exterior to the vascular cambium

the cambium and its immediate derivatives

a layer of dividing cells that forms the xylem toward the inside and the phloem toward the outside.

the outer covering of the plant that replaces the epidermis.

the amount of xylem produced in one year

Lens shaped openings that develop through the cork and allow exchange of grasses through the cork.

a file of parenchyma cells running from the pith to the cortex.

a waterproof material found in the walls of cork cells.

cork produced where living tissue is exposed to air.

the cell walls and intercellular spaces of a plant

the tendency of like molecules to adhere or stick together

an attraction between a positively charged hydrogen atom in a polar molecule and a negatively charged oxygen or nitrogen atom in another polar molecule.

thin, rotoplasic strands connecting cells.

a chemical bond in which electrons are shared unequally among participating atoms, resulting in differences in charge in different areas of a molecule.

an explanation for the way organic compounds, including sugar, move throughout the plant.

water molecules forming shells around ions, keeping them from interacting.

all the connected protoplasms of the cells of a plant.

in a column of water molecules, a result of the cohesion of water molecules.

the movement of organic compounds within the plant.

the evaporation of water from the leaf.
