First, let’s define plants as immobile, terrestrial, photosynthetic multicellular eukaryotes which are generally autotrophs and are derived from algae. Plants and algae have many morphological similarities but the terrestrial lifestyle of most plants sets them apart. Living on land presents new challenges in contrast to an aquatic lifestyle. Plants have to deal with engineering problems due to different physical conditions and this triggered the evolution of novelties in the reproduction mode.
