 ANGIOSPERMS (DICOT: ROOTS)
ML1142
 Herbaceous and woody roots, c.s.
Sections through representative annual root and perennial root of several years’ growth.
$9.45
 ANGIOSPERMS (DICOT: LEAVES)
  Roots and Stems— ComparisetTM
Compare the root and stem structures of a representa­ tive monocot (Zea mays, corn) and a representative dicot (Ranunculus acris, the buttercup). Root and stem cross sections of each plant comprise the four slides included. Students can closely examine and compare the arrangements of the vascular bundles (conductive tissues) in the two major groups of flower­ ing plants.

 Mitosis vs. Meiosis— ComparisetTM
This set of four slides is selected to introduce and compare and contrast processes which are integral to any study of biology—to say the least! Mitosis—cellular divi­ sion that results in two identical daughter cells; and meiosis—reduction division, the products of which are haploid sex cells or gametes; are examined in both plant and animal tissues. Slides for mito­ sis are sections of onion root­tip and whitefish blas­ tula. Slides for meiosis are sections of lily anthers and ovaries of Ascaris.
