5 Times Evolution Did Its Best
Usually when you think of evolution or natural selection, you think of survival of the fittest. But sometimes, the resulting traits of evolution aren’t the most efficient solutions to the problems at hand. With the bar set to “good...

5 Times Evolution Should Have Planned Ahead
Natural selection can lead to some pretty amazing adaptations, but sometimes the resulting traits aren’t the most efficient solutions to the problems at hand. With the bar set to “good enough,” here are some features that arose from...

How We Could Prevent a Global Rice Shortage
Rice production needs to see a 50% increase by 2030 to keep up with population growth, but as the climate warms, rice plants will likely become less efficient. Fortunately, scientists are working on a pretty clever potential solution.

Photosynthesis: Crash Course Biology
Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.

Types of Photosynthesis in Plants: C3, C4, and CAM
We learned about photosynthesis over in the biochemistry series. But now that we are taking a closer look at plants, we need to learn about the different types of photosynthesis that exist within the plant kingdom. The version we learned...

Photosynthesis: The Biochemistry Behind How Plants Make Their Food
Plants, unlike most living things, produce their own food through a process called photosynthesis. Photosynthesis means 'making using light'. Plants use the energy from the sunlight to make food. The food matter comes from carbon dioxide...

C-4 Photosynthesis
Comparisons between C3 and C4 photosynthesis begin in this video. Next, the mechanism by which CO2 is incorporated into a 4-carbon compound is explained. This is an involved topic which can be very complicated. It should be an excellent...

Photorespiration
Salman Khan delves further into the Calvin Cycle (light-independent reactions). This presentation presents the information at a college level.

Khan Academy: Photorespiration
The focus of this video lecture is the Calvin Cycle and a competing pathway called photorespiration. [11:04]
