Bio Lab Observation

One of my observations in Jean-Mance Park, the pale jewelweed, is the most recent common ancestor to Impatiens minor and can be found on 1 of the 2 branches of the Ericales genus placed on the phylogenic tree. As you zoom out, it can be seen that it is part of the Eudicots family, and further zoomed out, under flowering plants.

One adaptation that is shared between all observed species of flowering plants, angiosperms, is the rejection of pollen from its own anthers (the part of the stamen where pollen is produced) plant versus from others around it. This adaptation uses cellular responses to prohibit a flower’s own pollen from getting fertilized through the restriction of pollen tube growth, hence maximizing its growth.

One unique adaptation to the Purplestem Beggartick Bidens connata is the hook-like shape of the seeds that allows them to grab onto whatever they touch. This allows for more rapid seed dispersal of the plant as because the host acts as a dispersal agent.
