Reminder:

Be sure to follow all of the rules from producing figures for lab reports. One figure per page. Be sure the descriptive title for each figure includes appropriate taxonomic information. Corresponding to each figure, there should be a short paragraph that describes the significant features of the figure.

A. Draw prepared slides of:

·  Diatoms w.m.

·  Peridinium w.m.

·  Ceratium w.m.

·  Spirogyra Vegetative Single Chloroplasts w.m.

·  Chlamydomonas flagella stain

·  Volvox w.m.

B. Wet mount of live algae cultures

A. Rhizopus congregation

The Rhizopus Conjugation slide illustrates the formation of these zygosporangia. From your observations draw and label diagrams of several of these zygosporangia to illustrate their typical structure.

A. Rhizopus sporangia

From your observations of the slide (“Rhizopus Sporangia, w.m.”), draw and label several sporangia and their associated mycelia.

A. Yeast

Draw a labeled diagram of budding yeast cells from your observations of your microscope preparation.

B. Penicillium conidium

Draw and label a diagram of several of these conidia from your observations of the slide.

C. Lichen ascocarp

Draw and label diagrams that illustrate the algal cells among the hyphae and the structure of the ascocarp.

A. Mushroom life cycle

Draw and label a diagram that illustrates the structure of a typical fruiting body of a mushroom

B. Coprinus mushroom

Draw and label a diagram to illustrate basidia and their basidiospores on the gills.
