Vascular Plants
Record total magnification of all drawings.
Record type of section (transverse, longitudinal, whole mount, etc…).
Record genus and species if available.
PLEASE return slides to the proper place in the slide box.
Seedless Vascular Plants (Pteridophytes)
Phylum Pterophyta:
Make a simple drawing of the fern gametophyte (labeled ‘fern prothallium’ on the
slide). Label archegonia, antheridia, and rhizoids. See page 585 in your text.
Use Page 33 of your Rust manual as an additional reference.
Box 104
Phylum Pterophyta:
Make a simple drawing of the Equisetum cone (labeled ‘mature strobilus’ on the
slide). Label the sporangium and spores. See lecture handouts and Page 587 in
your text.
Box 107
Phylum Lycophyta:
Make a simple drawing of the Lycopodium cone (strobilus) labeling the
sporangium, sporophyll, and spores. See lecture handouts and Page 587 in your
text.
Box 121
Seed Plants
Gymnosperms (Page 593 - 597)
Phylum Coniferophyta:
Make a simple sketch of the male and female pine cones on display.
Make a drawing of a longitudinal section of a male cone (also called a male
strobilus or pine staminate cone). Label the microsporophyll, pollen grains, and
microsporangium (pollen sac). See Page 597 in your text & Page 36 of your Rust
manual.
Box 125
Make a drawing of a longitudinal section of a female cone (also called a female
strobilus). Label the ovuliferous scale (also called a megasporophyll), ovule, and
sterile bract. See Page 597 in your text & Page 36 of your Rust manual.
Box 126
Make a drawing of a few pine pollen grains. Note the ‘wings’ that aid in wind
dispersal. See Page 597 in your text & Page 36 of your Rust manual.
