What is a COMPLETE flower?
ALL FOUR floral parts are present: sepals, petals, stamens and carpals
What is a compound flower?
A compound or composite flower has fewer sepals, petals, stamens and pistils that are fused together. See image with two different types of florets or flowers:
What is CONNATE in plant taxonomy?
Connate means LIKE or similar parts are fused together. Read diagram description only, not labels on pictures to understand connate.
What is COROLLA?
ALL PETALS = COROLLA
What is DIADELPHOUS?
What is DIOECIOUS?
Each plant has either only male reproductive parts or stamens OR only female reproductive parts ir pistils.
DIOECIOUS plants NEED the plant of the opposite sex to achieve pollination

What does EPIPETALOUS mean?
Having stamens inserted on the Corolla (petals)
What is a FILAMENT?

What does FREE CENTRAL mean?
What does GYNOECEUM mean?
The FEMALE reproductive part of a flower
What does HYPANTHIUM?
Hypanthium or floral cup is a structure where basal portions of calyx, corolla and stamens form a cup shaped tube.
What does HYPOGYNOUS mean?
What is an IMPERFECT flower?
An IMPERFECT flower has male sex organs OR female sex organs but NOT BOTH
What is an IRREGULAR flower?
A flower which one or more members of a whorl, or several whorls differ from the others.
What is a LOCULE?
Chambers within the ovary in flowers and fruits. LOCULES contain ovules or SEEDS
What does MONADELPHOUS mean?
Stamens are fused together and anthers are free
What does MONOECIOUS mean?
Have both male AND female reproductuve organs in same plant
What is a NECTAR SPUR?
Is a hollow extension from a part of flower like sepals, petals or hypanthium that contains secrete NECTAR
What is an OVARY?
Enlarged basal portion of the PISTIL, the female organ of a flower
What is an OVULE?
Plant structure that develops into a seed when fertilized
What does PARIETAL mean?
Ovules develop on the INNER wall of ovary
What does PERFECT mean in plant taxonomy?
A perfect flower or bisexual flower has BOTH stamens and carpels
What does PERIANTH mean?
Perianth is a non-reproductive structure that holds sexual organs in a flower made of CALYX and COROLLA
What does PERIGYNOUS mean?
When STAMEN and CARPEL at the SAME kevel in the flower
What is a PETAL?
Petals are called the COROLLA. Petals are colored to attract pollenators and protect the organs. They have NO reproductive ability
What is a PISTIL?
Is the FEMALE reproductive part of a flower containing OVARY, STYLE and STIGMA
What is a RECEPTACLE?
The part of the flower stalk where flower parts are attached
What is a REGULAR flower?
A radially SYMMECTRIC flower. All of the members (parts like petals) are similar in shape and size.
What are SEPALS?
They are small green, leaf like structures that protect the flower when in bud stage and support petals when flower in bloom
What is a SIMPLE flower?
Simple or primitive flowers usually have many sepals, petals, stamens and pistils, while more advanced flowers have less of each and are usually fused together.
What are STAMEN?
The male fertilizing organ of a flower consisting of an anther ( contains pollen) and a filament.
What is a STIGMA?
The part of the flower where the POLLEN GERMINATES
What is the STYLE?
The tube-like structure that HOLDS UP STIGMA
What are the TEPALS?
What is ZYGOMORPHIC?
