Such a group is called a functional group. The âï»¿OH functional group is called a phenol (pronounced fee-nol) group if it is joined to a benzene ring. The same word, phenol, is also used as the name of the compound you made (2.3) consisting of a benzene ring carrying an âï»¿OH group and no other substituent groups.t is a carboxylic acid group and has a whole set of chemical properties that make it different to the âï»¿OH group. To simplify writing this functional group it is often abbreviated to âï»¿COOH or âï»¿CO 2 H. Some people refer to it as a âcooâ (rhymes with blue) group in conversation.
In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.
Many protists reproduce by mitosis until their environment deteriorates, then they undergo sexual reproduction to produce a resting zygotic cyst. Phases of Meiosis | Back to Top. Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).
