Which one of the following organisms reproduces sexually only once in its lifetime?
a. Banana
b. Mango
c. Tomato
d. Eucalyptus
Banana is an exceptional perennial plant. It reproduces sexually only once in its lifetime. Hence, it gives flowers only once in a lifetime. If further fruit is needed from a banana plant then the reproduction of the banana plant can be done by parthenocarpy – which is known as the seedless formation of fruit. Mango is a perennial plant because it grows and flowers for more than two years. Tomato is a perennial plant that continues to grow and flowers for more than two years. Eucalyptus is an annual plant. It completes its life cycle within one year and then dies. The answer is the option (a).
