Let us make a thin longitudinal section of the tomato berry and examine it under transmitted light! The tomato is covered externally by a membranous epidermis, beneath which the fleshy fruit wall can be seen. This, especially its outer part, contains a lot of red pigment (lycopene). In the middle, the placenta can be seen, to which the seeds are connected by a funiculus. The slimy seed coat of the tomato seeds forms the high water content jelly layer located under the fruit wall. This often completely fills the space between the inner surface of the fruit wall and the placenta. Make a horizontal section of the tomato as well and examine this under a magnifying glass! On the horizontal section, it can be clearly seen that the partitions of the fruit wall divide the inner space of the berry into three compartments (the number of partitions can vary in different varieties of tomatoes). The placenta’s rays extend into the three fruit compartments, to which the slimy-coated seeds are connected (Figs. 8.1, 8.2, 8.3, and 8.4).
