List two advantages of vegetative reproduction practised in case of an orange plant.
List two advantages of vegetative reproduction practised in case of an orange plant.
Official answer
Two advantages of vegetative reproduction in orange plants are:
- Orange plants have lost the capacity to produce seeds, so vegetative propagation is the only practical method to grow more orange plants of the same variety.
- Plants raised by vegetative propagation bear flowers and fruits earlier than those produced from seeds, so the farmer gets a quicker harvest.
Marking scheme
- 1.1 mark for stating that orange has lost the capacity to produce seeds, so vegetative propagation is the only method of reproduction.
- 2.1 mark for stating that plants raised by vegetative propagation bear flowers and fruits earlier than those grown from seeds.
Hint
Read the section on Vegetative Propagation carefully and look for the special mention of 'orange' as an example.
Quick oral answer
Q: Can you name any other plant, besides orange, that is commercially grown only by vegetative propagation? A: Banana, rose, jasmine and sugarcane are other common examples.
Common mistakes
- 1.Students often write generic advantages of vegetative propagation (e.g., 'no seeds needed', 'good qualities retained') without specifically relating them to the orange plant.
- 2.Confusing vegetative reproduction with grafting — they are not the same; grafting is one method that uses vegetative propagation.
- 3.Writing only one advantage in detail instead of two separate points.
Analysis and explanation
The NCERT chapter specifically states that vegetative propagation 'makes possible the propagation of plants such as banana, orange, rose and jasmine that have lost the capacity to produce seeds.' It also says that 'Plants raised by vegetative propagation can bear flowers and fruits earlier than those produced from seeds.' Since the question asks specifically about the orange plant, the seedless nature of orange is the most relevant advantage — without vegetative propagation, orange would be very difficult to cultivate commercially. The early-bearing advantage is universally applicable to vegetatively propagated plants.
Interesting facts
Orange, banana, rose and jasmine have all lost the ability to produce viable seeds — they exist only because humans propagate them vegetatively.
If left in the wild without human help, vegetatively propagated plants like orange would eventually die out because they cannot produce offspring on their own.
