The internal structure of a chloroplast. The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.
The Excel TIME function is a built-in function that allows you to create a time with individual hour, minute, and second components. The TIME function is useful when you want to assemble a proper time inside another formula.
Similarly, you can convert a time to hours by multiplying by 24, or to seconds by multiplying by 24*60*60, or to weeks by dividing by 7. Excel can also do arithmetic on times; so if you want to find the difference in minutes between times stored in A1 and A2, just enter the formula =(A2-A1)*24*60 in B2, and change the format.
