(2) the placenta allows nutrients to diffuse from the mother to the embryo.
Explanation:
The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.
Cell theory was given by Schleiden and Schwann in the year of 1839 which gave a basic idea about the cells and its relationships with an organism. The research on plants were done by Schleiden and on animals were done by Schwann.
<h3><u>Explanation:</u></h3>
Theodor Schwann was a German physiologist and physician who made different contributions in the field of science. His discovery of Schwann cells on neurons, the pepsin enzyme in stomach as well as the cell theory are worth remembering. Theodor Schwann did his research on animals and saw that the animal bodies are made up of different cells and their products just like plants. So on 1839, along with Matthias Schleiden, he gave the cell theory which stated that all the living organisms are formed of one or more cells and they are the structural and functional units of living organisms. In 1950s Rudolf Virchow added that cells do arise from pre-existing cells only.
