Microscopes and Slides—Prepared Slides, continued
Covers the nonvascular and vascular plants . Plants exhibit true multi-cellular organization and are charac- terized by cells enclosed by a cellulose wall . The anthophytes—or flowering plants—are presented as two classes, the monocots and the dicots, both of which are represented by a number of detailed anatomical and comparative slides .
PLANTAE
Sexual vs. Asexual— ComparisetTM
The myriad solutions to the reproduction puzzle fall neatly into two divi- sions—sexual and asexual . Both have their advantages and disadvantages . This five-slide set will help to illu- minate the basic differences and provide visual examples for each . Asexual reproduc- tion is shown by fission of Paramecium and by budding in Hydra . The complex structures often associated with sexual reproduction are illustrated by a cross section of a Ranunculus flower, and by separate cross sections of a mammalian testis and an ovary .

Muscle, Bone,
and Cartilage— ComparisetTM
Enhance your students’ understanding of the structure and function of the skeletal and muscu- lar systems . Discuss the numerous vital func- tions performed by these systems—in addition to their providing the frame- work for movement and posture . Included are five separate slides of stri- ated, smooth, and cardiac muscle, ground bone, and hyaline cartilage . The cellu- lar structure of the three muscle types can also be compared and contrasted .
