You will be required to identify all of these organisms by kingdom and phylum/division (phylum = animal, division = plant). If a genus name (italics) is given on this handout, you will be responsible for that as well. You must know all of the structures and terminology listed below. Due to the ever-changing nature of biology, the nomenclature used in lab may differ from that used in lecture. A labeled drawing and short written description is required for each numbered and highlighted organism. Please number your drawings accordingly. Be sure to use high magnification when necessary to see detail, and always note magnification next to each drawing. If in doubt,

Describe morphology, and the structures that are used for motility by each specimen. Label cilia, flagella, pseudopodia, nuclei, and cell membranes when present. 1. Phylum Rhizopoda – Amoeba (live, wet mount) 2. Phylum Foraminifera – Forams (prepared slide) 3. Phylum Actinopoda – Radilarians (prepared slide) 4. Phylum Zoomastigophora – Trypanosoma (prepared slide) 5. Phylum Apicomplexa – Plasmodium (prepared slide) 6. Phylum Ciliophora – Paramecium (live, wet mount): follow procedure on p. 17 of lab book to examine live specimen. • Algae: Autotrophic protests = photosynthesis (pp. 20 – 29) □ Observe each of the following, and draw in your notebook.
