Here students become acquainted with the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drink in fluids by pinocytosis.
Subjects: Biology
-
How Cells Obtain Energy
This program illustrates the mechanisms of photosynthesis and cellular respiration. It introduces ATP, the universal energy carrier molecule, and shows the structure and function of Chloroplasts and Mitochondria, energy transforming organelles.
-
How Cells Are Controlled
Illustrations show how genetic instructions carried on DNA are transcribed into RNA, leading to the production of specific enzymes that control the thousands of biochemical processes going on in living cells.
-
How Cells Reproduce
This program shows how DNA replicates, how copy errors occur and are fixed by repair enzymes, how DNA is compressed into chromosomes making possible mitosis and cell division.
-
Inside the Living Cell
In this introductory cell biology series, students learn all about cells and how they carry out the fundamental processes of life. The menu structure offers over 30 learning chapters that can be discussed and repeated as needed to assure that everyone is up to speed on the content. The large topics in modules covered are: The Cell-Unit of Life, The Outer Envelope, How Cells Obtain Energy, How Cells Are Controlled, How Cells Reproduce.
-
The Cell: Unit of Life
This program shows the kinds of cells and emphasizes the fact that all cells have a common organization and how all cells carry out similar biochemical processes.

DNA – Secret of Photo 51
NOVA investigates the shocking truth behind the discovery of the double helix structure of DNA and presents a moving portrait of a brilliant woman in an era of male-dominated science-Rosalind Franklin. Watson and Crick had seen a crucial piece of her data without her permission, an X-ray image, ”Photo 51,” that proved to be a vital clue in their decoding of the double helix. Narrated by Sigourney Weaver.

Cracking the Code of Life
ABC Nightline correspondent Robert Krulwich lends a lighthearted touch to genetic science in this provocative two-hour NOVA special that takes you inside the amazing, complex and contentious race to decode the human genome. The Human Genome Project was born in 1990, when an international consortium of labs set out to sequence all 3 billion letters of our DNA. Armed with this powerful information, medical pioneers are in the midst of astonishing breakthroughs that will change medicine as we know it. Will you get cancer, arthritis, or Alzheimer’s? The answer lies in your genetic code–but the question is: Do you want to know? And will these new discoveries eventually lead to cures?

The Unknown World
They’re hiding in your closet. They’re lurking in your bed. They’re all over you–snacking on your skin, burrowing through your scalp, munching on your mascara. They’re the creepy crawlers of the unknown world, and now–thanks to micro-photographer Lennart Nilsson, who brought us The Miracle of Life–you can (shudder) catch these critters in the act, magnified to monster size.
