Mitosis and Cell Division

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

What a packed lesson! Provide your class with the opportunity to learn about the cell cycle in several exciting ways. Biologists first learn about the theory behind mitosis, then proceed to view onion tips under the microscope and create...

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this activity is not only appropriate, but also highly valuable in...

The lecturer starts by emphasizing that the mitotic process is a separate mechanism from cytokinesis—the cytoplasm splitting to become two cells. The video continues by explaining the stages of mitosis in great detail. Each stage is...

A presentation which concentrates on the development of the blastocyst and embryo after fertilization. Topics begin with the scientific names and processes at each stage and then develop into an explanation of embryonic and somatic stem...

It is hard to believe a 300-foot-tall Redwood tree began as a single cell hundreds of years ago. How did it grow so large? Observe how different kinds of cells (bacteria, sex cells, and eukaryotic cells) reproduce or make more cells...

You slough off all your skin cells once every seven years. Thank goodness for mitosis, or we would all be looking pretty strange without skin. The video begins by reviewing the cell cycle, looks at an overview of cells undergoing...

Watch as an animated cell goes through the process of mitosis as DNA coils and bunches into chromosomes. Once the nuclear membranes dissolve, spindles pull chromatids to opposite sides and stretch the cell. The video ends as mitosis...

How does cancer begin, and why can it get so out of control? Curious young cytologists use an interactive resource to study the cell cycle. After reviewing the background information, individuals go step-by-step through the process of...
