Topic 5's Cellular Reproduction Flashcards, set of 22 flashcards

QuestionAnswer
Cell cycle All the stages a cell goes through including phases of growth, preparation for division, and division
Interphase Part of a cell's life cycle when it is living, growing, and getting ready to divide
Asexual reproduction Process of creating offspring or daughter cells using DNA from only one parent, and the resulting offspring or daughter cells are identical to the parent
Cytokinesis When copies of cell organelles (except the nucleus) move into new daughter cells
Mitosis Process of division of the nucleus in which the nucleus divides once to make identical nuclei for each of 2 identical daughter cells; a type of asexual reproduction
Chromosome What DNA is called during mitosis...DNA is wound up and easily visible
Daughter cells Name for cells at the end of cell division
Offspring Science term for children (relative to their parents)
Fission Type of asexual reproduction where an organism divides into two equal parts (the way bacteria reproduce)
Budding Type of asexual reproduction where a new organism grows from the body of the parent organism (hydra is an example)
Regeneration Type of asexual reproduction where a whole new organism grows from a piece of another organism (planarian worm is an example)
Diploid Adjective to describe a cell that has a set of matching chromosomes from each parent (46 chromosomes in a human, 23 from mom and 23 from dad)

Gamete General name for a sex cell
Sperm Name for a male sex cell
Egg Name for a female sex cell
Haploid Adjective to describe a cell that has half the normal number of chromosomes (one copy of each chromosome - usually a gamete)
Fertilization Process of sperm and egg joining
Zygote The name for a fertilized egg before it starts doing mitosis
Meiosis Process division of the nucleus in which the nucleus shuffles DNA then divides twice to make four unique nuclei,one for each of four haploid daghter cells called gametes; a type of sexual reproduction
Crossing over The "shuffling" of DNA that happens during meiosis
Sex chromosomes The 23rd chromosome pair that makes the difference between males and females, XX for females, XY for males
