on the same flower. (Compare with imperfect flowers.) Refer to Figure 2.
PERIANTH (which means "around the anthers") is the sepals and petals of a flower.
PERICARP is the fruit wall that develops from the ovary wall. The pericarp is divided
into the endocarp, mesocarp and exocarp.
PERICARPAL is the upper part of the flower stem, the receptable, and the lower part
of the pistil.
PETAL is one of the leafy structures that comprise a flower. Petals are often brightlycolored
and have many different shapes. They are located between the sepals and the
flower's reproductive organs.
PETIOLATE means having a petiole.
PETIOLE is a leaf stalk. On a compound leaf, the petiole extends from the stem to the
first set of leaflets. A leaf without a petiole is sessile. Refer to Figure 3.
pH is a value used to express relative acidity or alkalinity.
PHEROMONE is a substance secreted by an organism to affect the behavior or
development of other members of the same species; sex pheromones that attract the
opposite sex for mating is used in monitoring certain insects.
PHLOEM is the food-conducting tissue of a plant, made up of sieve tubes, companion
cells, phloem parenchyma, and fibers.
PHLOEM FEEDING is an organism that withdraws nutrients from the food-conducting
tissue of a plant's vascular system.
PHOTOSYNTHESIS is the process by which plants convert sunlight into energy.
PHYLLOCLADE is a flattened stem that looks like a leaf.
PHYLLODE is a leaf that has an enlarged midrib and no blades.
PINNATE COMPOUND LEAF is made up of many small
leaflets arranged in pairs on either side of a long central midrib (the
rachis). There is often a single terminal leaflet at the end of the
midrib. Refer to Figure 14.
