The photosynthetic apparatus is very similar to the one found in plants.

Chlorophyll fluorescence, an indication of the fate of excitation energy in the photosynthetic apparatus, has been used indicator for heat stress tolerance.

For example, transcription of nuclear genes encoding parts of the photosynthetic apparatus is regulated by light.

Some unicellular species rely entirely on external energy sources and have limited or no photosynthetic apparatus.

The enzyme is also thought to act as a safety valve for stress conditions in the photosynthetic apparatus.

The epithallium is a layer of many algae which bears the majority of photosynthetic apparatus.

It has been proposed that the before the evolution of leaves, plants had the photosynthetic apparatus on the stems.

Before the photosynthetic apparatus develops sufficiently in the early stages of germination, the stored energy reserves of starch nourish the seedling.

If photosynthesis is inefficient, excess light energy must be dissipated to avoid damaging the photosynthetic apparatus.

The photosynthetic apparatus is housed in these invaginations.
