Question

Do all flowers turn into fruit?

Answer 1

The main distinction between flower and fruit is that a flower is an angiosperm's reproductive organ, whereas a fruit is a seed-bearing structure that develops from the ovary. Flower and fruit are the byproducts of blooming plants' sexual reproduction. Gymnosperms, for example, generate ‘naked' fruits since they do not produce flowers.

Complete answer:
Fruits are produced by all flowering plants, however they all are not edible. Flowers are a plant's reproductive unit since they contain the reproductive organs of the plant. Flowers have both male and female reproductive components, with the stamen being the male reproductive part and the pistil being the female reproductive part.
The male plants of dioecious species do not produce fruits. But, if a plant that is not dioecious fails to produce fruit, then there is a “problem.” There may be several possibilities, such as
It may be a product of hybridization and meiosis fails to work properly (as in a mule).
There may have been a frost so “hard” that the flowers just fell off. It may be self-incompatible (its own pollen does not work on its own stigmas) and needs another plant for successful pollination (as in some varieties of cherry trees).
Yes, all flowering plants produce fruit but they all are not edible.
A plant that does not bear flowers would not be able to bear any fruits.

More likely than these is that the plant is experiencing environmental factors that are within its tolerance range for self (can grow, produce vegetative roots, stems and leaves) but are beyond the range of tolerance for producing flowers. Good examples of this can be seen in ornamental plants. Many nice ornamental plants seem to be flowering plants, but never produce flowers. If one moves the plant, such as moving a houseplant to a brighter window, it may flower.

They are usually only at their peak for a short length of time. Many plants, on the other hand, will not grow unless they are fertilised, and they will not generate seeds. The flower's ovary develops into a fruit, resulting in a seedless fruit.

Five plants which grow without flowers are cucumber, mustard, strawberry, watermelon, pineapple, avocado, Olive and Jackfruit.

Note:
Rose plants do produce fruit, which are normally red to orange in colour but can range from dark purple to black in some species. Rose Hips, also known as Rose Haws, form following successful pollination of flowers in the spring or early summer, and ripen in the late summer and autumn. After a rose has been pollinated, the petals fall off, revealing the rose fruit, also known as a hip. Rose hips are actually seed pods with dozens of seeds inside each one.
