and movement

Figure 2.1 Stentor and Trichodina pediculus are protozoans that have cilia.
Paramecia

Some of the most commonly studied ciliates are found in the
genus Paramecium. The paramecium in Figure 1.3 lives
symbiotically with green algae. The green algae undergoes

photosynthesis, providing nutrients to the paramecium.
A paramecium is a unicellular protozoan. It is enclosed by a The single-celled

layer of membrane called a pellicle. Directly beneath the Paramecium
pellicle is a layer of cytoplasm called ectoplasm. Embedded in bursaria hosts a
symbiotic green
the ectoplasm are the trichocysts, which are elongated,

function of trichocysts is not completely understood, but they biology careers,

guide food, primarily bacteria, into the gullet.

Green algae

bursaria provides a home for
green algae that enter the
paramecium during the
feeding process, but the green

Paramecium bursaria algae are not digested. 5
