Pollination

In geitonogamy, pollen is transferred to the stigma of another flower of the same plant with the help of a pollinating agent, so it is genetically similar to autogamy.
Xenogamy transfers pollen between different plants; apogamy is reproduction without fertilisation; cleistogamous flowers do not open and self-pollinate.

Honey is made from flower nectar, not by digesting pollen; it consists of sugars, minerals, enzymes and water.
So the statement about honey is not true.

Geitonogamy is the transfer of pollen from the anther to the stigma of another flower of the same plant.

Cleistogamous flowers never open, so self-pollination is assured and seed set does not depend on pollinators.

Commelina produces cleistogamous flowers, which never open.
Their anthers and stigma lie close together, so self-pollination and seed-set are assured even without pollinators.
Fig depends on wasps, Zostera on water and Salvia on insects.
