|Top 12 intersting facts about fruits|
Many fruits have tasty flesh, to tempt animals to eat them and so spread the seeds inside. But not all fruits are sweet and some aren’t even fleshy. Fruit is the seed-bearing part of a flowering plant and forms from the flower’s ovary.
Fruit grows as part of the lifecycle of a flowering plant. When pollen from the male parts of a flower lands on the female parts of another flower, the flower is fertilized and a seed is produced inside the ovary (the part of the flower that produces female
egg cells). The ovary wall swells up to protect the fertilized seed, forming the fruit. In a simple fleshy fruit, such as this peach, the skin, flesh, and seed case all form from the swollen ovary wall.
1. Raspberries are not berries at all but aggregate fruits—lots of fruitlets grown from a flower with multiple ovaries. True berries form from a single ovary, and include cucumbers, bananas, tomatoes, oranges, and grapes.
2. Also known as pitaya, the dragon fruit has a striking appearance but a bland taste. It’s the fruit of a night-blooming cactus grown across Asia and Central America.
3. Watermelons were first farmed in Africa 5,000 years ago. Prized for their high water content, they appear
in ancient Egyptian hieroglyphs, and seeds were even found in the tomb of King Tutankhamun.
4. Many nuts are actually a type of fruit. Instead of soft flesh, walnuts have a hard casing with a large, edible seed inside.
5. The durian is renowned as the world's smelliest fruit. Its powerful pong is often described as smelling like onions, cheese, or stinky socks.
6. Apples and pears are false fruits—the flesh develops from the flower’s base not its ovary. The true "fruit" is the core that surrounds the seeds, which most people throw away.
7. Wild bananas are full of bitter, inedible seeds. The bright yellow variety familiar from supermarket shelves has been cultivated to remove the seeds. Each fruit is a seedless clone genetically identical to all the others.
8. A pineapple plant produces just one fruit every 2–3 years. Pineapples are multiple fruits that form from up to 200 scalelike flowers fusing together.
9. Tomatoes were once believed to be poisonous, possibly because they
are related to deadly nightshade. Today more than 100 million tons of tomatoes are produced every year as food.
10. A coconut is a fruit but its white flesh is part of the seed. It is sometimes reported that falling coconuts account for 150 deaths every year. This figure hasn’t been proven but many tropical beaches have been cleared of coconut palms, just in case.
11. Pomegranates may have antiaging properties. They release a substance called urolithin -A that helps cells regenerate. In studies, worms fed this molecule lived almost twice as long as other worms.
12. Is eating apple cores bad for you? It’s true that apple seeds contain amygdalin, a chemical that releases the deadly poison cyanide. But you’d need to eat hundreds of pips, finely ground, to reach a dangerous dose.
