The pit protects the seed until it begins to grow and flourish, and it is the inner layer of the fruit, which is usually hard and inedible. There are pits in peaches, plums, cherries, nectarines, apricots, mangoes, and coconuts. This scenario may come as a surprise to people, but raspberries and blackberries have pits.
They grow in clusters, and each berry is a cluster of tiny fruits, as each berry has bumps that are the fruits. These fruits are called stone fruits. Fruits that have seeds include strawberries, blueberries, figs, grapes, apples, watermelon, cranberries, oranges, grapefruit, pineapple cantaloupe, and tomatoes.
Strawberry seeds are located on the outside of the berry. Apple seeds and cherry pits contain cyanogenic acids, which means that they can be dangerous in large quantities, but accidentally eating these pits and seeds in small amounts can be detoxified by the body. Some of these fruits even have both seeds and pits.
A seed is a fertilized and ripened ovule, usually enclosed in a seed coat. The ovule contains the embryo. In other words, the formation of the seed is after the fertilization of the ovule. It shows that the reproduction process is complete. The pit, on the other hand, should not be confused for seed because its function is to protect the seed. The pit functions mostly during the formation of the seed. To have a better understating of this, the pit is covered by the fleshy part of the fruit. Most fruits have their pit in the inner layer of the fruit. It is called pericarp in some fruits and can be a little bit hard too. While you can only see a pit inside a fruit, the pit can house so many seeds. Also, some fruits contain a lot of seeds, whereas a fruit can only contain one pit.
The pits are known to be part of the fruit that will be in charge of protecting the seed. The only time when the seed will not be protected anymore is when the seed is ready to be put out. The seed is known to be the ovule. This will contain the embryo of the plant.
This explains why a lot of plants can only grow when you plant the seeds on the soil, although there are some plants that can grow without the seeds. Another difference between the two is the number of pits and seeds that are available in one fruit. Fruits will only have one pit, but the number of seeds that are available in one fruit may vary. For example, a banana will have more than one seed, but a rambutan will have just one per fruit.
Seeds and pits are not the same, although both are most times found together in a fruit. A seed is a fertilized ovule encased in fruit and starts germinating when it falls into the right environment and might end up growing into a mature plant. Seeds are usually found in the fruits, but a part of the fruits which covers and protects the seed before it starts growing. Some fruits have pits which can be very hard, and also, some of these pits are eatable.
There can be a lot of seeds in fruit or inside a pit, but just a pit is most times seen in fruits. While seeds are present virtually inside every fruit, on the other hand, pits cannot be found inside some fruits. For instance, pits are not present in some fruits like mango, while pits are present in fruits like cherry, peaches, plums, etc.
