I have been puzzling over a grass question for almost a year now. I understand that almost all plants are able to take in nutrients from the soil, to store for winter, as long as there is chlorophyll to produce the necessary sugars and carbohydrates.
My understanding has been that beyond that, the plant will cannibalize the leaves to store the rest of its necessities for the winter.
My question is: If grass is still able to take up nutrients from the soil in preparation for winter would it not also manufacture the better chorophyll to produce the carbohydrates?
OR - Is it possible that Chorophyll A is only necessary that time of year and the darker green Chlorophyll B is no longer produced?
Thank-you for any hints.

I strongly suggest that you consult a recent text relating to plant physiology for the answer to your chlorophyll query. The publication by Lincoln Taiz and Eduardo Zeiger entitled PLANT PHYSIOLOGY, 2nd Ed will give an answer to almost any question relating to 'what makes plants work'.
A local college will probably have it.
