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 five­slide 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.

Sexual vs. Asexual— ComparisetTM
Price/Each
$44.30
Covers the nonvascular and vascular plants. Plants exhibit true multi­cellular 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.

ANGIOSPERMS (DICOT: STEMS)
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.
