Generalized organisms are usually relatively simple,or undifferentiated in structure the one from the other; they areconceived to be fundamental or stem types, from which specializedascendants may arise in the long courses of time. The orchidsare highly specialized plants. 258c. The environment is the sum of all the conditions or cir-cumstances in which a plant or an animal lives. Literally, it meansthe surroundings.
