Categorize the following into mitosis or meiosis

  • Has two rounds of cell division

  • Produces cells with half of the genetic material in them

  • Produces 4 cells

  • Produces two new cells

  • Produces identical cells (identical to each other and to the parent) as long as there are no mutations

  • Produces diploid cells

  • Is intended to repair tissue or grow the organism

  • Produces cells that can be used in sexual reproduction

  • Produces haploid cells

  • Makes sex cells/gametes

  • In a human it only in the ovaries or testes

  • Mitosis

  • Meiosis

  3. Metaphase 1

  4. Anaphase 2

  5. Prophase 1

  6. Prophase 2

Sort the following into each step of meiosis 1.

  • Spindle fibers pull apart the homologous pairs (separating the tetrads)

  • Crossing over occurs

  • 2 new nuclei may form

  • Centrioles produce spindle fibers

  • Spindle fibers that aren't connected to chromosomes start to stretch the cell

  • Spindle fibers break down

  • Spindle fibers move tetrads to the midline of the cell

  • Cell divides into 2

  • DNA coils and chromosomes form

  • Tetrads form

  • The nuclear envelope breaks down

  • Prophase 1

  • Metaphase 1

  • Anaphase 1

  • Telophase 1/Cytokinesis

Categorize the following into the steps of meiosis 2

  • The number of chromosomes doubles in the cell

  • Spindle fibers break down

  • Spindle fibers move chromosomes to the midline of the cell (not in pairs)

  • Spindle fibers stretch out the cell

  • The cell divides into 4 new haploid cells

  • Spindle fibers pull apart the sister chromatids

  • The DNA uncoils

  • 4 new nuclei form

  • Spindle fibers continue to be formed

  • DNA coils and chromosomes form (if the DNA uncoiled in the previous step)

  • Nuclear envelope breaks down (if two new nuclei were formed in the previous step)

  • Prophase 2

  • Metaphase 2

  • Anaphase 2

  • Telophase 2/Cytokinesis

Identify the following cells as products of mitosis or meiosis. I am only giving you an image of one of the cells.

  • A product of mitosis

  • A product of meiosis

Categorize the following as a step in mitosis or a step in meiosis. I am only showing you one cell in each diagram.

  • FYI: the top and bottom chromosomes are intended to be the same size

  • A step in mitosis
