A dioecious flowering plant prevents both :
A dioecious flowering plant prevents both :
Updated On: Jul 13, 2024
- Autogamy and geitonogamy
- Geitonogamy and xenogamy
- Clesitogamy and xenogamy
- Autogamy and xenogamy
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
When unisexual male and female flowers are present on different plants the condition is called dioecious and it prevents both autogamy and geitonogamy.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
