Fruits get the "Ha-etz" (הָעֵץ) blessing. In Jewish law, a fruit is defined as something growing from a perennial tree that does not renew its stem and does not grow too close to the ground. Thus, apples, grapes, nuts (except peanuts) and figs are fruit, but strawberries, watermelon and bananas are not.
Here's the blessing:
בָּרוּךְ אַתָּה יְ‑יָ אֱ‑לֹהֵינוּ מֶלֶךְ הָעוֹלָם בּוֹרֵא פְּרִי הָעֵץ
Bah-rookh ah-tah ah-doh-noi eh-loh-hay-noo meh-lekh hah-oh-lahm boh-ray pi-ree hah-aytz.
Blessed are You, L-rd our G‑d, King of the universe, who creates the fruit of the tree.
Listen to this blessing
After eating most tree-fruit, say Borei Nefashot (click here for audio and text). However, after eating grapes, figs, dates, pomegranates, and olives, say Al Hapeirot.
If strawberries, watermelon and bananas are not fruit, what are they, please?
Please see this link where it is explained that we make the Borei Pri Ha'adamah blessing for these foods.
See as well Rabbi Adelman's comment under that article as to the definition of the Hebrew word Pri in these blessings.
