Cell Division & Reproduction - Foundations to Biology



Sister chromatids line up in the middle of the cell

S phase

DNA is replicated (synthesized)


G1, S, and G2 are sub-phases of this phase


The nuclear membrane breaks apart and disappears


cleavage furrow and cell plate form


chromatids are pulled apart to opposite sides of the cell

Interphase or G1

cell is carrying out its normal activity and is not actively dividing


When the cell physical divides; splitting of the cytoplasm


two nuclei are visible and the nuclear membrane starts to reform


chromosomes become more relaxed and begin to uncoil

Cells are smaller and divide more often rather than grow larger because

1: DNA Overload 2: Cells need more 3: More efficient moving wastes and nutrients out

What is the correct sequence of the phase of Mitosis?

PMAT - Prophase, Metaphase, Anaphase, Telophase


The number of chromosomes in a body cell is represented by the symbol

Mitosis; Meiosis

Somatic cells are produced by ________________ and gametes are produced by _____________.


The structure that holds the sister chromatids together and helps to connect to spindle fibers

Sister chromatids

The two arms of a chromosome that are identical to one another are called?

16 chromosomes

During normal mitosis cell division, a parent cell having 16 chromosomes will produce two daughter cells, each containing

23 (they are haploid "half" the number of chromosomes)

How many chromosomes are found in a typical human sperm or egg cell?

Division rate

Cancer is a disorder in which some cells have lost the ability to control their...

Binary Fission

Prokaryotic cells create identical offspring during the cell division process known as?

Homologous chromosomes

Chromosomes that are similar in size and shape but carry different "options" for a gene or trait are called?

cell movement"; splitting one cell into two cells

Cytokinesis means?


Cells spend approximately how much time in Interphase preparing for division?

Mitosis & Cytokinesis

In the cell cycle, Cell Division includes which phases?


Meiosis or Mitosis? Chromosomes number is halved


Meiosis or Mitosis? Results in two identical daughter cells


Meiosis or Mitosis? occurs in somatic cells only


Meiosis or Mitosis? occurs in germ cells to produce gametes


Meiosis or Mitosis? crossing over occurs


Meiosis or Mitosis? one round of cell division


Meiosis or Mitosis? two rounds of cell division


Meiosis or Mitosis? Results in 4 genetically different cells
