FAQs on Parthenocarpy & its types Video Lecture - NEET
| 1. What is parthenocarpy? |  |
Ans. Parthenocarpy is a biological phenomenon in which fruits are formed without the process of fertilization. It is the development of fruit without the fertilization of ovules by pollen.
| 2. What are the types of parthenocarpy? | |
Ans. Parthenocarpy can be classified into two types: natural and induced. Natural parthenocarpy occurs in some plant species naturally, while induced parthenocarpy is artificially induced in plants through various techniques.
| 3. How does natural parthenocarpy occur? | |
Ans. Natural parthenocarpy occurs due to mutations or alterations in the genetic makeup of a plant species. These mutations can affect the hormones and enzymes responsible for fruit development, leading to the formation of seedless fruits without pollination.
| 4. What are the advantages of parthenocarpy in agriculture? | |
Ans. Parthenocarpy offers several advantages in agriculture. Seedless fruits produced through parthenocarpy have a longer shelf life compared to seeded fruits. They also have a uniform size and shape, making them more visually appealing to consumers. Additionally, parthenocarpic plants can be protected from diseases and pests that often target seeds and develop healthier fruits.
| 5. How is induced parthenocarpy achieved in plants? | |
Ans. Induced parthenocarpy can be achieved in plants through various methods such as hormone application, genetic manipulation, and mechanical stimulation. Hormone application involves the use of plant growth regulators like auxins or gibberellins to stimulate fruit development without fertilization. Genetic manipulation techniques can alter the genetic makeup of plants to induce parthenocarpy, while mechanical stimulation involves manually pollinating flowers to trigger fruit formation without fertilization.
