Transcript of closed captions:

0:05: We are approaching a redwood tree. To animate a scientifically accurate leaf, artists studied the texture of a redwood leaf specimen on a glass slide at high resolution. They even counted the stomata, and used that exact count for this film!

0:25: These leaves would be measured on a centimeter scale. Throughout the animation, we will gradually zoom in to smaller scales.

0:40: As we approach a single stoma, we are now on a millimeter scale.

0:48: As we enter the interior of the leaf, we see many individual palisade cells. These cells are where photosynthesis takes place; they are translucent to allow sunlight to enter.

1:00: As we approach a single palisade cell, we’ll zoom down to the micrometer scale. The shapes inside the cell are organelles: the bright globules at the bottom are the Golgi apparatus; the yellow spotted tubes are endoplasmic reticulum studded with ribosomes.

1:09: That large, blue membrane surrounds the nucleus; the purple blobs are mitochondria.

1:18: The faint, yellow, spider-web structure of the cytoskeleton provides structure and support to the cell.

1:24: You are about to enter a chloroplast; inside you see flat, pancake-like membranous structures called thylakoids. This is where the light-dependent reactions of photosynthesis take place to produce ATP, the cell’s energy carrier molecule. way


1:38: The time scale has changed: the molecules are shown moving 1 million times slower than in real life!

1:42: As we near an individual thylakoid, the animation scale continues to shrink down to the molecular level, where things are measured in nanometers.


1:52: The green and blue bush-like structures are photosystems: clusters of proteins that absorb light energy from the sun and help convert it into the chemical energy that’s stored in the bonds of the energy carrier molecule called ATP.

2:03: The yellow-green, rotating structure is an enzyme called ATP synthase. This molecular machine facilitates the flow of protons down their concentration gradient from one side of the thylakoid membrane to the other, using the energy released in the process to assemble ATP.

2:16: The pulses of light in the thylakoid membrane in which the photosystems are embedded represent energized electrons being passed from one photosystem to another, passing along the energy which will be stored in the bonds of ATP (the classic “bucket brigade”).

2:26: The small “wigglies” are ATP molecules. Living things store energy in the bonds of the ATP molecules and then use that energy to conduct all the processes of life.

This animation is a model, and has its strengths and limitations. In order to model something well, visual artists have to make decisions about what to represent and how best to do so.

What might seem as waste to Africa’s many herbivores is gold to the Dung Beetle who needs animals dung for its species survival. Not only do these dung beetles gather and roll as much dung as possible but they will even resort to high jacking another’s ball, which it has spent many hours perfecting. But not without a fight.

Roots Tonic | Jamaica Documentary

#rootstonic #jamaicadocumentary #ineverknewtv

For the people of the Sahara, owning a horse is a mark of status, a great pride. In villages of the dry savannah, children are taught to ride horses very young. They live a free and exciting cow boy life, watching after the family’s herd. This is the case of Hisseini, 11, who is soon to participate his first Grand Fantasia, a ritual horse race in which he will represent his village. But Hisseini has no one to train him.
At the cattle market, Hisseini meets Stephanie, a French woman who manages an equestrian club. He makes friend with her right-hand man Abakar. Abakar agrees to help Hisseini and introduces him to the white man’s way of riding horses. Hisseini also meets Estelle, a 12 year old French girl, getting ready for her first jumping competition with Stephanie. In a nearby town, Moussa is working as a stable boy for Atanase, a Greek man who has trained horses and jockeys in Africa for over 20 years. Moussa dreams to become a jockey like his brother Adoum. Adoum is to run for the Ramadan competition in the town’s central square. In that race, most jockeys ride barefoot, with no saddle nor stirrups.
The big day has arrived for Estelle, Adoum and Hisseini. They have to prove to their family that they are seasoned riders of the Sahara.
