plant sexual reproduction happens when pollen grains are transferred from a another male reproductive part into the stigma female reproductive part of a flower​

Sagot :

Answer:

Pollination in angiosperms is the transfer of the pollen grains from the anther of a stamen to the stigma of a pistil. The pistil of a flower may receive pollen from the stamens of the same flower, in self-pollination (e.g., peas and tomatoes). ... This process, double fertilization, occurs only in angiosperms.
