Since summer (and other seasons) can begin and end on different days each year on the astronomical calendar, it can be hard to compare seasons from year to year in this way. To standardize the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, in the meteorological calendar, summer includes the months of June, July and August - always starting on 1 June and ending on 31 August.
NADPH or NADP plus stands for Nicotinamide Adenine Dinucleotide Phosphate. NADPH is created in the Stoma on the duration of light reactions accumulation.

Light dependent Reactions. Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy. 1  Chlorophyll and other pigments absorb energy from sunlight.2  Water is used to provide electrons and hydrogen ions but also produces oxygen. 3  The electrons and hydrogen ions are used to create ATP and NADPH.etâs take a look at how these are collected by plants. 1  Carbon dioxide from the air passes through small pores (holes) in the leaves. 2  Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. 3  Sunlight is absorbed by a green chemical in the leaves.
