Why did early scientists believe that plants were fundamentally different than animals?

Both plant and animal cells have a mitochondria! Plant cells have a cell wall, a cell membrane and a chloroplast. Animal cells have a lysosome, where as plant cells usually don't have this present. 
        
             
        
        
        
The shuffling of chromosomes that occurs during both fertilization and meiosis can lead to genetic variation. This is because of the independent assortment and crossing over. Hope this answers the question. Have a nice day. Feel free to ask more questions.
