Question

Sujatha who is a native of a remote village wondered about finding seedless fruits in the market. How will you explain it to her about it?

Answer 1

Hint: Since Sujatha is from a remote village, she might have not known about the process used to create seedless fruits which are fairly common in the urban areas. She needs to explain the procedure behind the production of such seedless fruits.

Complete answer:
I will explain to Sujatha about the process of parthenocarpy which will help her understand how seedless fruits exist. Parthenocarpy is the natural or artificially induced process to produce fruits without the fertilization of ovules. This results in the production of fruits that do not contain seeds.
This parthenocarpy can be brought about in many ways.
-One way is by spraying the plant with any of the plant hormones gibberellins, auxins, and cytokinins which could stimulate the development of a parthenocarpic or seedless fruit.
-Another method is the hybridization of plants. Normal varieties of plants usually have two sets of chromosomes. Scientists have discovered genetically engineered varieties of plants that have four different sets of chromosomes. If a normal plant is pollinated with the pollen from a genetically-engineered plant, the resulting plants also called hybrids have three sets of chromosomes. This makes the new plants sterile and this allows the production of seedless fruits.

Note: -Another method of producing seedless fruits is known as stenospermocarpy which does not produce true seedless fruit.
-In this method, seeds are produced but are aborted when they are still small and immature.
-Most commercial seedless grapes such as the ‘Thompson Seedless’ are produced using this method.
