Yes, but they are considered a vegetable because they are not sweet. A fruit is any plant's organs that protect the seeds in the ovaries of flowering plants. The seed-producing portion of herbaceous perennial life for two or more years of reproductive structures. Some fruits are meaty and pulpy while others are dry and hard such as grapes, bananas, watermelon, etc., but all these declared fruits can't be called vegetables. It is said that the first humans ate fruit so they have some kind of sweet flavor, and fruit is rich in sugar. For example, an apple is a fruit because it is pulpy and contains seeds. It tastes sweet because there are sugar molecules inside of it, not just because it's considered a fruit. But olives are savory without any sugar so it's considered a vegetable. It does not have seeds as fruit does. The seeds of olives are in an ovary and are spread all over the olive stone. It is not a fruit, but it does have some similarities with fruits. Olives do not have any sugar inside. The seeds in olives are similar to the seeds stored inside of an apple, except that they are in olive stone and are said to be contained in follicles when the olive stone is crushed. The olive stone is the place where the olive fruit develops. During the first year, the green olives grow on trees, and in their second year, they drop to the ground. In this period there are two kinds of olives: green and black. Both kinds have a seed in them until they turn ripe, which is when you can harvest them. Until it turns ripe, they don't have any taste no matter how long you leave them on your table. When olives turn ripe, their color changes and the seed comes out from their stone. Olive oil is the liquid that comes out when olives turn ripe. Olive oil is extremely highly valued for its different uses such as olive oil soap and olive oil cosmetics such as face cream, eye cream, foundation, and body lotion. This high-valued commodity is on the verge of entering the world's largest market! What you have to do is crush it with a mixer, and it becomes olive paste or olive paste juice. Then the leftover paste is called olive paste. Although olives are considered a vegetable, they have the same nutritional value as a fruit because they are full of vitamins and minerals. And they try to put more oil into olives to make them more attractive to people because oil is the most valuable resource in their bodies, and this is why some people don't eat many of them.
