Using this outstanding kit, students will be challenged as they:
Identify the phases of plant mitosis
Observe chromosomal development
Gain hands-on experience with the micro-techniques
Stain and mount their own slides
Students prepare their own plant cells by treating scientifically grown onion root tips cells with a mild acid, then staining the cells. A stained section of cells is then squashed onto a slide and smeared into a single layer for microscopic study. All of the activities in this kit can be completed in a standard lab period. Kit is for 30 students.
Scientific Concepts:
Prepare a squashed stained slide of a root tip
Observe cells undergoing mitosis
Gain experience in microtechnique and staining
