NEET Solved Paper 2017 Question 55
Question: A dioecious flowering plant prevents both:
Options:
A) Cleistogamy and xenogamy
B) Autogamy and xenogamy
C) Autogamy and geitonogamy
D) Geitonogamy and xenogamy
Show Answer
Answer:
Correct Answer: C
Solution:
- Dioecious plants have distinct male and female individuals, meaning that a single plant will have either male or female flowers, but not both. This separation prevents self-fertilization (autogamy) and also prevents fertilization between flowers on the same plant (geitonogamy). However, it does not prevent cross-pollination between different plants (xenogamy).
