Types of Pollination by Pollen Source — NEET
📚 Practice ConceptKinds of Pollination: Depending on the source of pollen, pollination can be divided into three types.
Which of the following statements regarding megasporogenesis and female gametophyte development in angiosperms are NOT correct? S1: The megaspore mother cell (MMC) is a diploid cell that undergoes meiosis to produce four haploid megaspores. S2: In all angiosperms, all four megaspores formed from meiosis are functional and directly contribute to the formation of the embryo sac. S3: Monosporic development of the embryo sac refers to its formation from a single functional megaspore. S4: The functional megaspore, typically located towards the chalazal end, undergoes mitotic divisions to form the female gametophyte. S5: The primary role of the nucellus in the ovule is to provide a landing platform for pollen grains after pollination.
