Lecture 4: Flower Terms Flashcards
What does the carpel consist of?
Stigma, style ovary
What does the stamen consist of?
Anther filament
What 4 parts make a complete flower?
Calyx, corolla, androecium, gynoecium
What are male and female incomplete flowers
Female psitaliate, male stameinate
____ male and female flowers present on the same individual and _____ male and female flowers develop on different individuals
Monecious, Dioecious
True or False: There are also polygamous plants: e.g. with hermaphrodite, male and/or female flowers on the same individual or on different individuals.
True
______ tepals resemble petals: they are large and nicely colored
Petaloid
______ tepals resemble sepals: they are small and greenish
Sepaloid
______ is radial symmetry and _____ is bilateral symmetry
Actinomorphic, Zygomorphic
What are the two types of calyx and corolla?
Free or fused
What are the 6 types of fused corolla?
salveform = corolla tube narrow-cylindrical and lobes more or less perpendicular on it.
ligulate = corolla tube narrow cylindrical opens asymmetrically into one formation called “ligule” (which is the result of fusion among all the petals).
tubular = corolla is tubular with teeth or lobes.
bell shape
urceolate = shaped like an urn.
bilabiate- labia
rotate = corolla tube is very short and the lobes are flared in such a way the flower looks like a wheel or like a start
What are the 4 types of androecium?
Didynamous: Androecium with 4 stamens: 2 have longer filaments, and 2 shorter
Tetradynamous: Androecium with 6 stamens: 4 have longer filaments, and 2 shorter
Monadelphous: All the stamens are fused in a group (regardless of their number)
Diadelphous: Stamens fused in 2 “groups”. In the case of Fabaceae: one group has 9 stamens and one “group” only 1 stamen
What the two types of gynoecium?
Inferior or superior ovary
What are the 3 styles of gynoecium?
Mocarpous = 1 carpel Apocarpous = free carpels Syncarpous = fused carpels
In order to be apocarpous or syncarpous, the gynoecium must have 2 or more carpels.
