Chapter 10 - Vocabulary Review
1. Describe how the following terms are related to one another.
asexual reproduction, sexual reproduction: Both produce a new organism:
asexual reproduction involves one parent, offspring have the same DNA
sexual reproduction involves two parents, offspring are a mixture of DNA
chromosome, centrioles: Centrioles are structures in animal cells that organize
spindle fibers so duplicated chromosomes can be separated during mitosis
centromere, chromatid: A centromere is an area on chromosomes where spindle
fibers attach and pull apart sister chromatids during mitosis
binary fission, mitosis: Binary fission is the process by which duplicated DNA in
prokaryotes is separated between two new cells (organisms). Mitosis is similar in
that it involves the separation of duplicated DNA between dividing cells in
eukaryotes; unlike binary fission, mitosis is not typically a way to produce an new
organism.
