Pericarp: The portion of a fruit that covers a ripened ovary. made up of three parts, the innermost called the endocarp, the middle layer called the mesocarp and the outer layer, called the exocarp or epicarp. The edible part of the fruit often varies. While one might eat the skin of a peach I would not suggest the same for an orange.

Petals: The colorful outer segments of the flower which serve to attract pollinating insects. Some petals have markings only bees can see.

pH In gardening it pertains to the measure of the Hydrogen ions in moist(with water) soil using a logarithmic scale. The scale range is from 0 to 14 with 7.0 being neutral. Most soil however, falls within 5.0 to 9.0.

Phenology Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and inter-annual variations in climate, as well as habitat factors (such as elevation, rainfall and sunlight).

Phenophase: An observable stage or phase in the annual life cycle of a plant or animal that can be defined by a start and end point. An example would be an open blossom till it dies or falls off the plant.

Phototropism: The orientation of a plant in response to light. Turn a plant away from a light and phototropism takes over reorienting the plant toward the light.


Phloem:Translocates food and nutrients from leaves to growing parts of the plant and to the roots where they is stored. Like the veins and arteries in your body the Phloem is moves water and nutrients to other locations.

Phycology: The study of algae.

You will find this term in the plants edit section under
the Plant Type category.

Polar Vortex:A large scale cyclonic atmospheric condition around the north and south poles. They are cold low pressure patterns, located in the troposphere and extending into the stratosphere, increasing size in the winter and shrinking in the summer. Fed by temperature differentials between the tropics and polar regions they rotate counterclockwise in the Arctic and clockwise in the Antarctic.
