ABSTRACT
Diploid cells have one system more than bacteria. Phylogenetically, this addition seems to be related to sexuality. Morphologically, the nucleus is covered within the cell. The new accomplishment of diploid cells is that they can produce multicellular organisms. The change from a haploid cell to a diploid cell indicates a new organization of inner and outer systems. The first stage of evolution was characterized by materialization and reification of Transcendental Subjectivity (TS) in an inner system. The second stage consists of an introjection of the environment of the pro-caryotic cell into a diploid inner system and an eu-caryotic cytoplasm and membrane. The TS is represented in the diploid cell, a representation that enables the cell to communicate with other cells and with matter beyond its own border. An additional condition for the communication relation beyond the cell is the organization of DNA and RNA in the nucleus.
