1 BIOLOGY MCQS

The fruits without seed, like banana, are called:

  • Seedless fruits
  • Parthenogenesis fruits
  • Parthenocarpic fruits
  • Placental fruits
Correct Answer: C. Parthenocarpic fruits

Detailed Explanation

Some fruits, such as bananas, grapes, and pineapples, develop naturally without seeds. These are scientifically known as parthenocarpic fruits. The process through which these fruits develop is called parthenocarpy, which means the formation of fruit without fertilization of ovules.


In most plants, fruits develop from fertilized flowers where male pollen fertilizes female ovules, forming seeds inside the fruit. However, in parthenocarpy, the fruit develops from the ovary of the flower without fertilization, resulting in seedless fruits. This can occur naturally in some plants, like bananas, or can be induced artificially by applying plant hormones such as auxins and gibberellins in agriculture.


Parthenocarpic fruits are widely cultivated because they are more convenient to eat and often preferred by consumers. Bananas, for example, are triploid plants that do not produce viable seeds but can reproduce vegetatively from suckers. Farmers propagate these plants without needing seeds.


The other options given in the question are incorrect:




  • Seedless fruits: A general term; not the scientific name.




  • Parthenogenesis fruits: Parthenogenesis refers to reproduction without fertilization in animals, not plants.




  • Placental fruits: Fruits do have a placenta (tissue holding seeds), but this term does not define seedless fruits.




  • Organic fruits: Grown without chemicals; unrelated to seed presence.




Parthenocarpy is an important concept in plant biology and agriculture. It helps scientists and farmers develop seedless varieties of commercial fruits to improve quality and consumer demand. Other examples of parthenocarpic fruits include seedless oranges, seedless grapes, and cucumbers grown under controlled conditions.


This MCQ belongs to Biology, specifically plant reproduction and fruit development, highlighting how certain fruits form without the normal fertilization process.
