Photosynthesis and seedless fruit videos

Saw a couple of interesting videos on the Be Smart channel:

first one on photosynthesis:

In grade school I remember watching: Our Mr. Sun and wondering about the take on photosynthesis, the details of which weren't really known in the 1950s.  

photosynthesis is mentioned at about 36 minutes:

This is undeniably true:
although imperfect, photosynthesis gets the job done

I also got a kick out of this:



I actually have confused Joe of Be Smart with the guy on the right, Hank Green, of Scishow, who got cancer, lost his hair in treatment, then regrew his hair after remission but it came in curly:

The second video:



seedless fruit: https://www.youtube.com/watch?v=H8c1ObYSlQI

Reminded me of the book: The Botany of Desire by Michael Pollan.

  He tells the "real" story of Johnny Appleseed.  Even seeded fruit like apples are all basically clones: apples don't breed true from seed.  So when a "good" variety of apple is found the grower must get grafted trees to plant.  Apparently there was a Red Delicious tree in Iowa somewhere that is the source of all of those nice looking but bland apples in the store.  Johnny Appleseed may have distributed apple seeds but these were not for growing trees with eating apples, Pollan contends that they were for apples to make hard cider.  I do have a couple of volunteer apples trees on the property and one of them produces apples that aren't too bad.  The other produces spitters although our dog, Buddy, would eat them to the extent that we buried him next to his favorite tree :)

Here is the wiki: https://en.wikipedia.org/wiki/The_Botany_of_Desire

The other thing that I found interesting is that Joe actually bought and ate the infamous (the topic of the Yes, We Have No Bananas song) Gros Michel banana:

Apparently the Gros Michel ships well and tastes better than the Canvendish bananas we all get at the grocery store.  It's apparently just a matter of time before we lose the Canvendish banana to a similar plant disease that got the Gros Michel.
