BASIC PROCESSES 2 Basic Processes In order to survive all organisms need to reproduce. The process of reproduction is different in different life forms. The most common form of reproduction is asexual. The simplest is sexual reproduction. Asexual Reproduction is when one cell becomes two under favorable environmental conditions. This process is called binary fission in prokaryotic cells and mitosis in all others. In some bacteria, the resultant cells separate immediately and become independent organisms. Conjugation is the simplest form of sexual reproduction. This is when a pilus, a cytoplasmic bridge, develops between two individuals through which a one-way exchange of genetic material occurs. There are three different types of life cycles: the Diploid cycle; this cycle is seen in all animals, some protists, and algae: Haploid cycle; this is frequently seen in fungi, and in some algae: and, alternating cycle; all plants and some algae live this life cycle.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
