Vedclass · Answer

(B) The primary reason for the failure of fruit formation in many cultivated rose varieties is that they are often 'double-flowered' cultivars. In these varieties,the stamens (male reproductive organs) have been evolutionarily or artificially modified into additional petals through selective breeding. Because the stamens are absent or non-functional,there is no production of pollen grains. Without pollen grains,pollination cannot occur,and consequently,fertilization does not take place. Since fruit formation is a post-fertilization event (where the ovary develops into a fruit),the absence of fertilization leads to the failure of fruit development.

Rose plants produce large,attractive bisexual flowers but they seldom produce fruits. On the other hand,a tomato plant produces plenty of fruits though they have small flowers. Analyze the reasons for the failure of fruit formation in rose.
