Domesticated banana plants produce seedless fruit because they are ________.

  1. a. triploid
  2. b. monocots
  3. c. endangered
  4. d. treated with colchicine
  5. e. propagated by grafting
  6. f. infected with Phylloxera

Summary Introduction

Introduction: A developing plant that is covered by a protective outer covering is called as seed. They is the results of fertilization of the ovules. Vegetative reproduction is a mode of asexual reproduction from which new shoots and roots are developed from the fragments of a parent plant. They include budding, cuttings, grafting, and air layering techniques. The seedless fruit produced by certain plants can be propagated through the process of grafting.

Explanation

Reason for correct answer:

All the commercially produced banana plants produce seedless fruit because they are triploid (3n). These three chromosomes will not be divided equally between the two spindle poles during the meiosis I process. As a result, the possible gametes are not formed. Thus, the seeds are not produced.

Some plants produce fruits even though the fertilization process does not take place. As a result, the fruits that are developed from these unfertilized flowers will not have seeds. The seedless fruits can also be formed when the plants having mutations cause embryos or ovules to terminate during their development.

The seedless fruit produced by certain plants can be propagated through the process of grafting. The seedless fruit produced by certain plants can be propagated through the process of grafting. But the grafting is difficult in banana. So, the banana is propagated either by using tissue culture techniques or from shoots that sprout from nodes on their corms.

Option a. is given as “triploid”.

All the commercially produced banana plants produce seedless fruit because they are triploid (3n). These three chromosomes will not be divided equally between the two spindle poles during the meiosis I process. As a result, the possible gametes are not formed. Thus, the seeds are not produced.

Hence, the correct answer is option a.

Reasons for incorrect answer:

Option b. is given as “monocots”.

The seeds containing only one cotyledon are called monocot seeds. But the domesticated banana produces seedless fruit...
