How can a single celled organism sustain life
Web4.4: Life Cycle of the Multicellular Eukaryote. Alexey Shipunov. Minot State University. The life cycle of a unicellular organism begins with syngamy: one cell unites with cell having different genotype. To recognize each other, cells which are going to fuse ( gametes) frequently use surface proteins, like cells of our immune system. WebWhile prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular. For example, most protists are single-celled eukaryotes! Even though prokaryotes do not have a nucleus, they DO contain genetic information. Prokaryotes generally have single circular chromosomes where they store their genetic information.
