Partners in crime II – chloroplasts and mitochondria

Chloroplasts are found in the cells of plants that conduct photosynthesis. They absorb sunlight and use it along with water and carbon dioxide gas (CO2) to produce food for the plant.

Mitochondria generate the energy that cells need to function. The energy made by the mitochondria is in the form of a chemical called adenosine triphosphate or ATP.

Mitchell’s equation I

This work belongs to the Mitchell’s dream series, inspired by the Chemiosmotic hypothesis that penetrates all biology. The Nobel prize winning British biochemist Peter Mitchell first published his ideas on the proton motive force in Nature in 1961. The equations here suggest the mitochondrial network.

Erich Gnaiger wrote a short paper inspired by these images. You can read it here.

Light wall – moss leaf

This image shows the leaf of a wall moss under the microscope. A wall moss is a small flowerless plant that grows in a dense green clump. The individual plants are usually composed of simple, one-cell thick leaves, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients.
