That would be the chloroplasts. They are small cells in a leaf that store chlorophyll.
The development of seeds are considered to one of the most important in the evolution of land plants especially the spore-bearing vascular plants. The seeds will serve as the alternative means of dispersal for reproduction purposes especially in areas where there is no water.
It is because they have hydrophilic phosphate groups that are attracted to water and hydrophobic fatty acid tails that avoid water.
Hope this helps!
