Crucially, the photorespiratory pathway is a major source of H2O2 in photosynthetic cells.
Unveiling Prochlorococcus: The Life and times of the ocean's smallest photosynthetic cell.
The action of HetR, in turn, is mediated by inhibitors that control how often a photosynthetic cell turns into a nitrogen-fixing one.
For example, for photosynthetic cells light can be eliminated for several hours and then re-introduced.
Most chloroplasts in a photosynthetic cell do not develop directly from proplastids or etioplasts.
Moist air is trapped in between the rows of lamellae, while the larger terminal cells act to contain moisture and protect the photosynthetic cells.
The leaves of Sphagnum have large dead cells alternating with living photosynthetic cells.
Bundle-sheath cells are photosynthetic cells arranged into tightly packed sheaths around the veins of a leaf.
The outer layers of leaves are designed for maximum solar absorption, containing two to three layers of photosynthetic cells.
Shaded leaves are generally broader and thinner, having only a single layer of photosynthetic cells.
