The photosystems are named after the wavelength for which they are the most reactive. Photosystem II is P680 which means that it has the highest reavtivity when light that is 680 nanometers (nm) hits it. Photosystem I works off the same principle; however, it is named P700 because the optimal wavelength for it is 700 nm.

Where does photosystem 2 and photosystem 1 take placein the organelle?
Photosystems I and II are both in the thylakoid membranes of the chloroplast.
What are cluster of chlorophyll called?
Photosystems Photosystems
Photosystems are found in the structure called what?
There are two photosystems, and they can be found embedded in the thylakoid membranes. They are linked by electron transport molecules.
What is the evidence that there are two photosystems in plants?
The evidence for two photosystems in plants comes from experiments using isolated chloroplasts, which have shown that two distinct light reactions occur in the thylakoid membrane. Additionally, differences in absorption spectra and electron transport pathways of Photosystem I and Photosystem II provide further evidence for the existence of two separate photosystems.
Why are there several structurally different pigments in the reaction centers of photosystems?
Having multiple structurally different pigments in the reaction centers of photosystems allows for a broader absorption spectrum of light. This enables the photosystem to capture light energy across a wider range of wavelengths, maximizing the efficiency of photosynthesis. Additionally, these pigments work together to transfer excitation energy towards the reaction center, where it is converted into chemical energy.
