Question:
Is the size of a lemon determined by the number of seeds it has?



Replies:
You have the opportunity to determine the answer yourself. Buy a dozen lemons, measure their weight and their circumference along the North-South direction and also along the East-West direction with a tape measure. You can use a piece of string and then measure the string.

Cut each lemon into several, maybe 6 to 8, cuts along the North-to-South axis of the lemon. Extract the seeds with a fork, or other pointed tool. Count them. Now you can measure the number of seeds in a lemon against the size of the lemon.

You now see that one has to be careful about what you mean by "the size" of the lemon. Is it the circumference in the East-West or the North-South directions? Is it the weight? There are many kitchen scales that are accurate enough for your needs.

Or is it the average of the various "sizes", North-South compared to East-West? This gets you into a very important subject -- What do measurements mean? This is far more advanced than you need to go.

Also be aware, depending upon the lemon species, the answer may be none!

The size of a fruit is determined by many factors including genetics and growing conditions (soil fertility, water availability, and so on).

A larger fruit might have more seeds depending upon the type of fruit/tree.
