- a A cell containing two sets of chromosomes (2n), one set inherited from each parent.
- b A cell containing only one set of chromosomes (n).
- c A haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.
- d The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
- e A display of the chromosome pairs of a cell arranged by size and shape.
5 Multiple choice questions
- The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
- The phenomenon observed in normal animal cells that causes them to stop dividing when they come into contact with one another.
- The spread of cancer cells to locations distant from their original site.
- An ordered sequence of events in the life of a cell, from its origin in the division of a parent cell until its own division into two. The eukaryotic is composed of interphase (including GG1, S, and GG2 subphases) and M phase (including mitosis and cytokinesis).
- The complex of DNA and proteins that makes up eukaryotic chromosomes. When the cell is not dividing, it exists in its dispersed form, as a mass of very long, thin fibers that are not visible with a light microscope.
5 True/False questions
synapsis → The pairing and physical connection of duplicated homologous chromosomes during prophase I of meiosis.
gametophyte → In organisms (plants and some algae) that have alternation of generations, the multicellular diploid form that results from the union of gametes. it produces haploid spores by meiosis that develop into gametophytes.
cytokinesis → The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.
somatic cells → A haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.
interphase → The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.
