Question

Propagation of a rose plant is through
A) Flower
B) Stem
C) Fruit
D) Root

Answer 1

Hint: The agamogenesis in roses may occur through stem cutting. The new rose plant shaped from the cutting is analogous to the parent plant and the area is unremarkably big by this methodology.

Complete answer: Sexual reproduction in rose plants happens with the fusion of male and feminine gametes created by the plant. The male gametes are created by the method of microsporogenesis that happens in the reproductive structure whereas the feminine gametes or eggs are usually created within the ovary of the flower. When maturation of gametes occurs the next step is the fertilization of gametes which happens when male reproductive cells reach the feminine gametes for fertilization to give rise to new rose plants. The agents which help in this process of pollination are called pollinating agents e.g.: insects, wind, etc. Thus after fertilization, an embryo is formed which gives rise to a new rose plant. Rose plants are propagated or reproduced by means of cutting the stems (or shoots) as follows: a bit of the stem (or facet shoot) having bud is cut from associate existing. The lower part of this gutting is buried in dampish soil. After a few days, the top of the cutting buried in soil develops roots and afterward grows to become a brand new rose plant.
Hence option B i.e. stem is the correct answer.

Note: The plants like rose, vine, Chrysanthemum, grapes, sugarcane, bananas, and cactus, etc. may be grown by the means of stem cutting. Stem cutting could be a style of vegetative propagation. This itself is enough for the expansion of plants.
