उत्तर
No, pollination and fertilization are not required in apomixis. Apomixis serves as an alternative method to sexual reproduction, even though the female reproductive structures are utilized during the process. In apomictic plants, embryos can develop directly from cells such as the nucellus, synergid, or egg without the need for pollination or fertilization. Hence, neither pollination nor fertilization is necessary for apomixis to occur.
