This program explores the basic structure of both animal and plant cells and the specific functions that different cell components serve. After an overview of a complete cell, individual segments dive in to detail each of the specific parts. Discrete, pedagogical segments cover: the plasma membrane, extracellular matrix, flagellum and cilia, the nucleus, nucleolus, nuclear envelope, cytosol and cytoplasm, the rough and smooth endoplasmic reticula, the golgi apparatus, ribosomes, lysosomes, vacuoles, peroxisome, and mitochondria. Where plant and animal cells different is made clear, and separate segments on structures unique to plants include the cell wall, plasmodesmata, and chloroplasts.
There are some 300,000 species of flowering plant on Earth. A small number have so captivated humans across the ages that they have become iconic. This series explores the biological and botanical history of four iconic plants, tracing each species’ epic journey across millennia.
The campfires of our ancestors; the ships with which we first explored the globe; instruments, artwork, buildings, furniture— these are only some of our innumerable uses for wood.

Nature or Nurture?” is a long-running debate in the social sciences, one heavily-influenced in the popular imagination by the idea "DNA is destiny” – the belief human behavior is broadly determined by a "good” or a "bad” roll of the genetic dice.
We are capable of precisely reprogramming the genetic code of our body’s cells, embryos, bacteria, viruses and plants. With the CRISPR-technology we can alter the characteristics of every organism to our own design. In doing so we will be able to eradicate diseases, improve the condition of our bodies and alter plants to meet the specific needs of our food consumption.
