CELLS alive! Library: Contents of Volume 5

Diverse organisms from a farm pond.

5.1 Diverse organisms from a farm pond.

These are shown with both optical and electronic color enhancement and include mixed populations of rotifers, ciliates, euglenoids, bacteria and more, all from a 600 sq. ft. farm impoundment.

Amoeba proteus (Sarcodinid)

5.2 Amoeba proteus (Sarcodinid)

Motility of this protozoan is shown at 2x normal speed to highlight cytoplasmic flow. Visible are the nucleus, vacuole and numerous organelles and food inclusions.

Paramecium multimicronucleatum

5.3 Paramecium multimicronucleatum

Sequences show the motility of this ciliated protozoan and the repetitious activity of both anterior and posterior contractile vacuoles.

Spirostomum (ciliated protozoa)

5.4 Spirostomum (ciliated protozoa)

Though they look a bit like worms, these are ciliates that move with a gentle gliding motility.

Stentor

5.5 Stentor  

Shows the slow deliberate movement of this ciliate, as well as the internal structure including the string of nuclei.

Euglena

5.6 Euglena

The organelles of this flagellated alga are clear, such as the red eyespot, the chloroplasts, and the flagella. Unrestricted, Euglena moves in a rotating motion using its flagella. When restricted between slide and coverslip, the pellicle gives and the Euglena can flex using its internal contractile machinery.

Volvox (Flagellated alga)

5.7 Volvox (Flagellated alga)  

Shows the gentle tumbling motility of this flagellated colonial alga.

Philodina (Rotifers)

5.8 Philodina (Rotifers)  

Shows leech-like movement and the characteristic cilia from which they get the name "rotifer" and with which they procure food. Shows smaller organisms being moved by the cilia.

Daphnia pulex (Crustacean)

5.9 Daphnia pulex (Crustacean)

Shows beating heart, eggs in brood pouch, and the saltatory swimming motion that gives them their common name "water flea".

Cephalobus (Nematode)

5.10 Cephalobus (Nematode)   

Nematodes are roundworms and have both a mouth and anus. Some nematodes are parasitic, but most are free-living and found in soil and aquatic habitats. VERY WIGGLY!
