- density dependent inhibition
- asexual reproduction
- a 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.
- b 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.
- c 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.
- d The phenomenon observed in normal animal cells that causes them to stop dividing when they come into contact with one another.
- e The spread of cancer cells to locations distant from their original site.
5 Multiple Choice Questions
- A chromosome that is not directly involved in determining sex; not a sex chromosome.
- 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.
- A modified type of cell division in sexually reproducing organisms consisting of two rounds of cell division but only one round of DNA replication. It results in cells with half the number of chromosome sets as the original cell.
- A haploid reproductive cell, such as an egg or sperm. unite during sexual reproduction to produce a diploid zygote.
- In organisms (plants and some algae) that have alternation of generations, the multicellular haploid form that produces haploid gametes by mitosis. The haploid gametes unite and develop into sporophytes.
5 True/False Questions
cell cycle → specific location of a gene on a chromosome
gene locus → specific location of a gene on a chromosome
alternation of generations → 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.
homologous chromosomes → A chromosome responsible for determining the sex of an individual.
cytokinesis → 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.
