Bio 1108 Lab Practical #1 (Protists, Fungi
and Microscope)
Mechanical Stage - ANS-means of holding and moving the slide on the stage
Scanning Objective - ANS-4X
High Power or Dry Lens - ANS-40x
Objective - ANS-10X
Depression Slide - ANS-A microscope slide with a circular depression in its center
Volvox - ANS-Motile Microorganism - multi-cellular colony with concentrated colonies
(daughter colonies), sphere, unicellular algae (photosynthesis)
Colonial - ANS-Composed of a loose association of many individual cells.
Chlamydomonas - ANS-single celled green alga, a small egg shaped cell with 2 flagella
and a single chloroplast has two small contractile vacuoles.
Ulva - ANS-multicellular green algae, contains specialized cell types a group of cells at
the base forms holdfasts that attach it to rocks
Spirogyra - ANS-colonial green algae, filamentous, individual cells joined together in
long strands
Conjugation - ANS-Two haploid filaments joining by a conjugation tube, followed by
movement of one cells contents to the other cell. The nuclei fuse to form a diploid
zygote, which will eventually undergo meiosis to produce new daughter cells.
Zygote - ANS-Diploid cell that will eventually undergo meiosis to produce new daughter
cells.
Chondrus - ANS-Red Algae protists, preserved specimen, common name: Irish Moss.
Color can range from yellowish green to red to dark purple or purplish brown. species C.
crispus, multicellular.
