Answer:

Step-by-step explanation:

Hibiscus flowers attract pollinators with their bright colors and a bull's-eye pattern leading to a deep throat. The deep throat and prominent stamen and stigma mean pollinators need to bump the stigma to probe deeper in the flower. Pollen sticks to the pollinator and is transferred to the female parts of either the same flower or sometimes a different flower. Pollinators are rewarded for their pollination efforts by by being allowed to consume the surplus pollen the flowers produce.not sure about spider lily

answer for 2 The top part of the pistil is called the stigma and is sticky so it will trap and hold pollen. In flowering plants, the flower functions in sexual reproduction.

answer for 3 The ultimate function of pollen is to deliver male gametes (sperm) from the stamen of a plant to an ovule for fertilization of an egg, which then develops into a seed
