how outbreeding devices in flowering plants helps in cross pollination?
plz say how(explain)
Answers
Answer: The out breeding devices that flowering plants have developed receptivity stigma that releases pollen grain that is not synchronized which helps stop self -pollination.
Three outbreeding devices that flowering plants have developed: Receptivity of stigma and release of the pollen grain is not synchronized, i.e., stigma becomes receptive much before pollens are released or after they are released to avoid self-pollination.
Flowering plants have developed many devices to discourage self pollination and to encourage cross-pollination. ... This is a genetic mechanism and prevents self-pollen (from the same flower or other flowers of the same plant) from fertilising the ovules by inhibiting pollen germination or pollen tube growth in the pistil.
