Dragon fruit is an exotic cactus that is found in Asia, Mexico, and parts of South America. It is not grown in North America or Africa, which is why the plant is not as common in these regions. Dragon fruit can be planted as ornamental plants, but they do bare delicious fruit that is rather tasty.

Which is why I was pleasantly surprised to see it growing pretty well in my Country Nigeria. Again, this is another confirmation to the humungous potentials of our country

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’s present in this model, and what’s intentionally missing or altered? Find out by visiting https://www.calacademy.org/edu....cators/travel-deep-i

The Food and Agriculture Organisation FAO, is calling for the transformation of Africa’s agri-food system to make healthy diets more affordable. A new report shows Africans are missing out on the nutritiuos foods such as fruits, vegetables and animal proteins due to high costs. The report also shows the number of undernourished in the continent has risen to over two hundred and fifty million people.

This is a step by step instructional video on how to make a Tyre Home/Kitchen garden. It is one in a series of videos produced under the 1 Million Home/Kitchen Garden Initiative by the Ministry of Agriculture, Livestock Fisheries and Cooperatives in Kenya. The initiative is part of Government of Kenya's response to the global outbreak of the COVID-19 Corona Virus.

This is a documentary highlighting on the progress of The Small Scale Horticulture Development Project (SHDP) Which is jointly funded by Africa Development Bank (ADB) and The Government of Kenya through the ministry of Agriculture.

We promote Permaculture with an African perspective through intercultural exchange, Youth and Women's empowerment and sustainable farming programs. visit http://betterworld-cameroon.co....m/what-we-do/project

Interview Tanjo of Satang Jabang on permaculture
The benefits of permaculture in the Casamance. Tanju, a member of the managing board of the school Satang Jabang relates how the Jardin Botanique in Kafountine was founded. Permaculture being one of the solutions to counter drought in Africa as it preserves and maintains the water balance.

Interview with Mugove Walter Nyika, coordinator of the 9th International Permaculture Conference and Convergence (IPC9).  The IPC9 will be held in Africa in November of 2009. Nyika discusses the history of Permaculture in Africa, what participants can expect to find at the Conference, why the "Green Revolution" isn't really green, and the role that Permaculture plays in Africa's move toward sustainability.
