Pollen, seeds, flowers, and fruits are considered among the most advanced characteristics in the plant kingdom. What evolutionary advantage(s) does each of these offer (relative to what existed before)

Advantage of plant kingdom

Explanation:

Capacity tissue to sustain development and a defensive coat give seeds their prevalent transformative preferred position. A few layers of solidified tissue forestall drying up, liberating propagation from the requirement for a steady stock of water.  Flowering  plants have a regenerative favorable position over gymnosperms due to various adjustments, for example, having blossoms t consider fertilization and organic product for seed dispersal. Fertilization can be permitted by wind, or by dust being conveyed by creatures.  Seed and pollen were innovative structures that improvement of the undeveloped organism,to vanquish dry land and permitted seed plants to break their reliance on water for proliferation. The dust grains are the male gametophytes, which contain the sperm (gametes) of the plant.

This bacteria must be very strong as it has a large amount on antibiotic targeting it. this bacteria could be one of many different types and it is very hard to tell which one with out more information.
