In each fruit, were there similar patterns in which the seeds were arranged? Does the same type of fruit always hold a similar number of seeds, or does the amount vary a lot? Repeat this activity but this time use a ruler to measure each fruit before you count their seeds to see if larger fruits tend to produce more seeds than smaller ones.
You can also use a scale to weigh each fruit as an alternative way to measure fruit size. Do larger fruits make more seeds? Dissect several different varieties of seedless fruits and look for seeds.
Are "seedless" fruit varieties completely seedless, or simply have fewer seeds than normal? What is the decreased seed productivity of seedless varieties compared with normal varieties on a fruit-to-fruit comparison basis?
Observations and results Did some types of fruit clearly have more seeds than others? Did the cucumbers, squash, tomato and pepper have a lot of seeds, easily over each? Did the apple only have a few seeds, no more than 10? Fruits are divided into three general groups, with the "simple fruits" group making up the majority we encounter. They're formed from one ovary in one of the plant's flowers. As the ovary turns into fruit, different ovary parts become different fruit parts; when fertilized, small structures called ovules become the fruit's seeds—and more fertilized ovules means more seeds!
The other two fruit groups are more complex. In "aggregate fruit"—such as raspberries—multiple ovaries fuse on a single flower. In the third group, called "multiple fruit," many ovaries and flowers unite. A pineapple is a good example of a "multiple fruit. You are commenting using your Facebook account.

Find some unusual fruits. Record each fruit on a chart and leave spaces for how many of each type of fruit counted and the total number of seeds. Cut each fruit in turn and count the seeds. Put them in a paper cup or other container to keep track. Count several of each fruit to get a better count of seeds.
Write down all the data and compare the productivity of the fruits, which is how many seeds each type creates. Divide the number of seeds by the number of pieces of fruit counted for each type. Twenty seeds in five apples would be a productivity total of four per fruit.
Ask yourself how apples compare to the other fruits. Which fruit had the most and least seeds? Were there any patterns of production?
