|Plant Taxonomy 2015 Study Guide for Quiz Wednesday, September 16
Be sure you can label all the floral parts on Figure 4.16 in Judd et al. You need to be able to identify, define and label the stigma, ovule, carpel, gynoecium, filament, stamen, androecium, petal, sepal, calyx , corolla, perianth, pedicel, bract, anther, connective, ovary, style.
Understand difference between complete vs. incomplete flowers.
Understand difference between bisexual vs. unisexual flowers; monoecious vs. dioecious.
Understand difference between carpellate and staminate flowers.
Patterns of floral symmetry: actinomorphic (radial), zygomorphic (bilateral)
Funnelform vs. Salverform corollas
Apo- (distinct) vs. Syn- or Sym- (connate) as in syncarpous, apocarpous, sympetalous, apopetalous etc: see pg. 64 Judd et al.
How is adnate different from connate? What are the four floral whorls?
Number of parts: 4-merous, 5-merous etc.
Insertion types and inferior vs. superior ovary: study Judd et al Figure 4.21: hypogynous with superior ovary, epigynous with inferior ovary (conspicuous or inconspicuous hypanthium); what is a hypanthium? Perigynous with superior ovary (hypanthium=floral cup)
Placentation: axile and parietal especially, see Judd et al Figure 4.22
Miscellaneous terms: locule, tetradynamous, monadelphous stamens, diadelphous stamens, exserted, included
The Angiosperm Life Cycle (Study J&C Figure 4.17 on page 63)
Be able to define, label, and know the ploidy level and function (and whether mitosis or meiosis was involved) where appropriate of:
Microsporangium, microsporocyte, microspore, microgametophyte, pollen, intine, exine, columella, tectum, generative nucleus, vegetative nucleus, pollen tube, sperm nuclei and how many (2), double fertilization and what it means, micropyle, endosperm, megasporangium, megasporocyte, megaspore, megagametophyte, egg cell, antipodal cells, synergid cells, polar nuclei, testa, tegmen, nucellus, reduction of the gametophyte and how it relates to green plant phylogeny, alternation of generations, zygote, gametes, sporophyte, gametophyte, haploid, diploid, triploid, mother cell, seed coat, surviving megaspore, mature female gametophyte consists of 8 nuclei in 7 cells (usually), endosperm is triploid nutritive tissue for the developing embryo, pollen contains the mature male gametophyte, male gametophyte is NOT the same as sperm
