Photosynthesis is composed of two main parts (light-dependent and light-independent). Photosystem I (PS I) and photosystem II (P
S II) are alike in many ways. How does photosystem I and photosystem II differ from one another? A) PS I produces glucose while PS II produces ATP. B) PS I occurs in the stroma while PS II takes place in the thylakoid membranes. C) PS I is a light-independent reaction while PS II is a light-dependent reaction. D) PS I absorbs the longer wavelength of light while PS II absorbs a shorter wavelength of light.
Photosystem I and II differ from each other in following ways –
a) Light absorbed in PS I has a longer wavelength as compared to light absorbed in PS II. PS I absorbs light of wavelength 700 nm while PS II absorbs wavelength of 680 nm
b) PS I receives electron through the ETC after the PS II completion. While PSII gets its electron form splitting of water.
The microscopic observations of cells form the basis of the cell theory and the idea that all living things are composed of cells; cells are the structural and functional unit of living things.
