Bioflix activity: meiosis -- comparing mitosis and meiosis can you identify the similarities and differences between mitosis and
meiosis? to review mitosis, watch this bioflix animation: mitosis. to review meiosis, watch this bioflix animation: meiosis. part a - two types of cell division drag the labels onto the grid to indicate the phases of mitosis and meiosis. use only pink labels for pink targets.
1. Similarities: they are both processes of cell division by which cells reproduce. They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps. In both cases the cell duplicates its DNA by pulling it
apart into two sets, place the sets on each end of the cell, and then
divide down the middle.
Both produce new cells
based on their parent cells' genes.
2. The differences:
Mitosis: - has 1 division per cycle - one cell produces 2 new cells - the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same) - it occurs in somatic cells Meiosis: - two divisions per cycle. - one cell when divides produces 4 new cells - the new cells have different genetic information. mixes the the genetic material from the
parent cells - the number of chromosomes of the daughter cells is half of the mother's.
Answer: What substances dissolve in ocean water. This is the only question that can be answered through scientific investigation because it is the only question that can be tested. The other questions cannot be answered through scientific investigation because they based on opinions which are more abstract.
