Answer:
1, Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
2, Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. ... There are two kinds of photosystems: photosystem I (PSI) and photosystem II (PSII) (Fig. 3.3).
3, Thomson's cathode ray experiment and Rutherford's gold foil experiment.
