What are gametes? - Sex cells (sperm and egg)
What is uncontrolled cell growth? - Cancer
What is the longest cell cycle phase? - Interphase
What are the stages of interphase? - G1, S, G2
What happens during G1? - Cell is preparing to divide (growth & development)
What happens during S? - DNA is replicated
What happens during G2? - Organelle synthesis; new organelles created for new cell
What do chromosomes contain? - Genetic information (DNA)
What is the longest phase of the cell cycle? - Interphase
What is mitosis? - Division of the nucleus
What kind of reproduction is mitosis? - Asexual reproduction
What are the phases of mitosis? - Prophase, metaphase, anaphase, telophase
When do chromosomes become visible? - During prophase
What happens during prophase? - Chromosomes condense and coil, become visible
under microscope, the nuclear membrane breaks down, centrioles migrate to opposite poles,
and microtubules form Spindle
What happens during metaphase? - Paired chromatids lineup in the middle of the cell,
(equator), and then they attach to spindle via centromere
, What happens during anaphase? - Centromeres split, sister chromatids separate, become
individual chromosomes, move towards opposite poles, and microtubules of spindle pull them
to opposite ends of cell; cell elongates
What happens during telophase? - Chromosomes uncoil, spindle disappears, and nuclear
membrane reappears
What stage are most cells in? - Interphase
How can you tell if a cell is in interphase? - Chromosomes are not visible
What organelle in "animal" cell division is not present in plant cell division? - Centrioles
Why are all chromosome numbers even? - Chromosomes are stored in pairs; 1 set from
each parent
What are homologous chromosomes? - Corresponding chromosome pairs; carry genes
for same traits
diploid cell - has two full sets of chromosomes (1 from each parent) (2n)
haploid cell - has one set of chromosomes (n)
What is the cell cycle divided into? - Interphase and cell division
2 phases of cell division - mitosis and cytokinesis
cytokinesis - Division of the cytoplasm
products of mitosis - 2 identical daughter cells
How is cytokinesis different in plant and animal cells? - Animal cells divide by cleavage
furrow; plant cells divide by cell plate
What type of cells undergo mitosis? - Eukaryotic somatic cells
What does it mean to be 2N diploid? - 2 full sets of chromosomes
All of your body cells are 2N diploid except? - Sperm and egg cells
what cells frequently undergo cell division? - Skin, digestive, connective tissue, bone,
blood, and cancer cells
proteins that regulate the cell cycle - cyclins
two factors that slow cell division - limited space and nutrients
