Naturally I¹m with Bob about this and, for that matter. with Einstein as in

"Everything should be made as simple as possible, but not one bit simpler."
...Albert Einstein

Hence my use of this same quote in
<http://www.digitalpublisher.co.uk/Oxygraphics/ohwhat2.htm> where the whole
argument is restated ad nauseum.

If anyone doubts the trouble that over simplification causes in this context
take a look at http://en.wikipedia.org/wiki/Talk:Photosynthesis

Bob, Depending on the level of instruction, this seems rather like splitting hairs. For introductory students, it seems enough to let in go at what the textbooks are saying. And while I don't claim to have quite as much experience as you, during some of our TEM investigations, I think I recall seeing stroma lamellae connected to the inner membrane of the chloroplast.

Sometimes it's easy to forget how much introductory students need to learn.

Subject: Fwd: [Plant-education] Glucose is no more a product

The bottom half of my last email got cut off.

Chloroplasts are enclosed by a double-membrane
envelope composed of an outer and an inner
membrane (Fig. 10b). A common misconception seen
in most biology texts is that the double-membrane
envelope...

David,

Forgive me for returning to an old theme that I have troubled you with in
the past.

For half a century or more, it has been clear that the path of
starch synthesis in chloroplasts starts with triose
phosphates and progresses to polymer formation via
glucose-1-P rather than free glucose. Glucose is no more a product of carbon
assimilation by illuminated chloroplasts than is sucrose.
So, why do textbooks insist that it is?.

If you wish to read a recent article about this you can find it by pasting

into Google

It all happens inside a 2x2x.25" recorder that can be uploaded to a
computer.

We would like to monitor light intensities in our greenhouse and have the data saved in a laptop. Does anyone have a suggestion for an inexpensive radiometer that has data acquisition capability?
