5 Written questions

5 Matching questions

  1. alternation of generations
  2. asexual reproduction
  3. mitosis
  4. interphase
  5. density dependent inhibition
  1. a The period in the cell cycle when the cell is not dividing. During this phase, cellular metabolic activity is high, chromosomes and organelles are duplicated, and cell size may increase. often accounts for about 90% of the cell cycle.
  2. b The generation of offspring from a single parent that occurs without the fusion of gametes (by budding, division of a single cell, or division of the entire organism into two or more parts). In most cases, the offspring are genetically identical to the parent.
  3. c A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants and some algae.
  4. d The phenomenon observed in normal animal cells that causes them to stop dividing when they come into contact with one another.
  5. e A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei.

5 Multiple choice questions

  1. The pairing and physical connection of duplicated homologous chromosomes during prophase I of meiosis.
  2. A method of asexual reproduction by "division in half." In prokaryotes, it does not involve mitosis, but in single-celled eukaryotes that undergo this, mitosis is part of the process.
  3. A cell containing two sets of chromosomes (2n), one set inherited from each parent.
  4. 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).
  5. The X-shaped, microscopically visible region where crossing over has occurred earlier in prophase I between homologous nonsister chromatids. they become visible after synapsis ends, with the two homologs remaining associated due to sister chromatid cohesion.

5 True/False questions

  1. S phaseThe synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.


  2. G2 phaseThe first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.


  3. sporophyteIn 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.


  4. somatic cellsA haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.


  5. metastasisThe spread of cancer cells to locations distant from their original site.
