REVIEW - LAB QUIZ 2
REMEMBER: The emphasis of the lab quiz will be in identification of structures or organisms. Each station will have something for you to look at, either alone or on a microscope.
Name a plant to Division (Lycophyta or Polypodiophyta)
Lycopodium specimens: rhizome, microphyll, dichotomous branching, strobilus
Lycopodium stem x.s.: vascular bundle, cortex
Lycopodium strobilus l.s.: sporangia, spores, homosporous
fern vegetative morphology: rhizome, frond, pinnae, sorus
fern prothallus: antheridia, archegonia, rhizoids
fern frond with sporangia: annulus, sporangia, spores
GYMNOSPERMS
Recognize material to Division: Coniferophyta and Ginkgophyta
Pines – Be able to recognize the following structures:
fascicle, needle, staminate cone, ovulate cone (1st and 2nd year)
Staminate cone slide: microsporophyll, microspore, pollen
Ovulate cone slide: ovuliferous bract, scale, ovule
from cones determine when pollination and fertilization have occurred
Ginkgo – Know the species name! (Ginkgo biloba)
Leaves: deciduous, dichotomous venation
Reproduction: recognize the staminate and ovulate "cones", dioecious?
Be able to recognize an organism as belonging to one of the particular Divisions, including
Penicillium, Aspergillus, mushroom, earthstar, etc.
Saprolegnia slide: oogonia, zoosporangium, hyphae
Culture and slide of Rhizopus: asexual structure
sexual reproduction: structures and process
Cup fungi: sexual process & structures; how many spores per ascus?
Club fungi: sexual process & structures; mushroom anatomy
Lichens: What organisms are commonly included in lichens?
recognize the types on the slide
