After treatment the tomato seedlings were incubated at 30 C for 48h under fluorescent lights providing 200μmolm -2 s -1 of photosynthetically active radiation.

The range of photosynthetically active radiation for PNS bacteria is 400-1000 nm.

In almost all cases these are photosynthetically active organisms (plants, cyanobacteria and a number of other unicellular organisms; see article on photosynthesis).

This huge amount of damage can result in almost total loss of photosynthetically active leaf area as well as reducing or prohibiting pollination.

Engelmann hypothesized that the bacteria were moving in response to oxygen generated by the photosynthetically active chloroplasts in the algae.

It is red-pigmented, not being photosynthetically active.

"Test of current definitions of photosynthetically active radiation against leaf photosynthesis data".

Geosiphon bladders are photosynthetically active, and are also capable of fixing nitrogen from the atmosphere.

Mixotrophic dinoflagellates are photosynthetically active, but are also heterotrophic.
