A farmer wants to do farming of roses. Which of the methods of propagation should be followed ?
(A) Spore formation
(B) Gamete formation
(C) Cutting
(D) Fragmentation
Answers
Answer:
A. Spore Formation is a method in Asexual Reproduction. ... When Sporangia burst; minute single-celled, thin or thick walled structures called spores are obtained. Under suitable conditions, they develop into a new Plant.
b. Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
c. Cutting is the separation or opening of a physical object, into two or more portions, through the application of an acutely directed force. Implements commonly used for cutting are the knife and saw, or in medicine and science the scalpel and microtome.
d. the process or state of breaking or being broken into fragments.
Explanation:

For farming of roses, the method of propagation to be followed is Cutting(option C).
What is vegetative propagation?
- Vegetative propagation is a type of asexual reproduction in plants wherein new progeny(clone) is grown using fragments of the parent plant.
- Vegetative propagation can include methods such as propagation by leaves, underground stem, adventitious roots, etc.
What is Cutting?
- Cutting is a type of vegetative propagation in which a part of the parent plant is cut, such as root or stem, and allowed to grow into a full plant by providing a suitable environment to it.
- If a stem cutting is planted, it will grow roots and vice versa.
- In the case of a rose, stem cutting is an effective method of growing clones. A cutting is allowed to grow in a nutrient-rich environment and supplied with appropriate hormones.
Thus, rose follows the Cutting method of propagation.
