Holy crap, I know even less than I thought I did.

Just middle school or somewhat high school knowledge on concept of photosynthesis.

I know a bit. Was a forestry major for a couple of years....before I realized there weren't many jobs looking for the skill. Pretty cool that they did include the Krebs cycle in there. That was a fun bit to learn about.

ETA: It's unfortunate that they only refer to the reverse Krebs cycle in the linked article. Most people understand that plants consume CO2 and emit O2, yet the Krebs cycle requires that plants take in O2 and produce CO2. Might check out some reading on Photosynthesis and Respiration. Photosynthesis stores the energy, but the citric acid cycle puts that energy to work within the cells of the organism.

I know that things that are black absorb the most wave lengths of light, so you'd think that with how efficient nature is, that leaves would be black. Instead they are green, which I believe is one of the least present wave lengths that get through our atmosphere. I heard something about this on some podcast or another, but couldn't remember which one. So like most everyone else, I know next to nothing.

You perceive (see) green leaves because the plant does not absorb green light, it reflects it. They are absorbing most of the spectrum which easily passes through the atmosphere.

Is it then that the green is one of the more prevalent colors then? Either way, the point of the discussion was that you'd think the plant would be a different color than green, but it's not.

Only roughly understand what it is. I never was good at math.

My 17yo daughter loves biochemistry, so I got to hear about it more than I really needed to...

Topic is slowly transitioning from general biology to analytical/spectro chemistry.

Fun fact: The average human can only distinguish about 20 shades of blue, but more than 3000 shades of green...
