HELP: chlorophyll in mosses

[j.kerslake]

HI...

Could anyone please help with the following question:

Is biosynthesis of chlorophylls and carotenoids light - dependent in 
bryophytes (particularly mosses) in the same way as it is in angiosperms?

If so, which wavelengths are required?

Any references?

(this is for a friend who is studying mosses under snowbeds)

Thanks for any help.....

Jim (for Clare).
