TRUE has the value of 1 and FALSE has the value of 0. So if you are only getting TRUE and FALSE results, you can add them directly, like you would any numbers. If as a result of your functions you are getting other numbers, like you could from an IF function, then you can add those values with standard methods too.

Cells are the fundamental element of a worksheet. All formulas are put into them. Most functions and formulas will reference cells on the worksheet. So cells are extremely important in Excel. Without them, you do not have a worksheet.
The Logical category functions are the ones most appropriate, like the IF function, but some functions in other categories could be used too, like SUMIF in the Math & Trig category.
Yes, plant cells contain DNA. They contain it because DNA is necessary to the cells so that they can carry the instructions to carry out life functions and reproduce.Nucleus and chloroplasts
Practically all formulas and most functions will reference cells, so there is an infinite amount of answers. They can use any cell or cells on your worksheet. There are some functions that don't refer to cells, like NOW, but most will do so.
