If pollen grain is transferred from anther to stigma of the same flower, it is called Correct Answer Autogamy
The correct answer is Autogamy.
Key Points
- Pollination : The process of transfer of pollen (from male reproductive part i.e. anther) to the stigma (from female reproductive part i.e. carpel) of flowering plants is called Pollination. After pollination fertilization (fusion of male and female gamete) takes place and flower turns into fruit.
- Kinds of pollination : Pollinations can occur either within a flower or between flowers of the same plant or flowers of different plants. Depending on this, pollinations are of three types, namely:
- Explanation :
- Autogamy - Transfer of pollen grains from anther to stigma of the same flower.
Figure. Autogamy (A type of Self-pollination)
Example of plants - Viola, Oxalis
Additional Information Geitonogamy - Transfer of pollen grains from anther to the stigma of another flower of the same plant.
Example of plants - Cucumber, pumpkin
IXenogamy - Transfer of pollen grains from anther to the stigma of another flower of the different plant.
Example of plants - Papaya.
HintSyngamy (A part of the fertilization process)
Figure. Syngamy (fusion of male gamete fuses with egg)
- An important characteristic of angiosperms is double fertilization, The pollen tube releases two male gametes into the embryo sac. One of the male gametes fuses with an egg to form a diploid zygote. This is called syngamy & other fuses with a diploid secondary nucleus is called triple fusion.
- This phenomenon of two fusions is called double fertilisation and is unique to Angiosperms (flowering plants).
- Zygote forms the embryo.
- During syngamy, the zygote is produced which forms the embryo.
