Why is mitosis important in multicellular organisms?
Mitosis is essential for growth and repair.
Mitosis ensures that diploid reproductive cells divide twice, forming four haploid daughter cells.
Mitosis is responsible for passing on genetic variability and beneficial mutations to the next generation.
Mitosis allows tissue growth in multicellular organisms by resulting in the formation of gametes, which then form new cells.
A single prokaryotic cell can divide several times in an hour. Few eukaryotic cells can divide as quickly. Which of the following statements best explains this difference?
Eukaryotic cells are smaller than prokaryotic cells.
Eukaryotic cells have less DNA than prokaryotic cells.
Eukaryotic cells have more cell walls than prokaryotic cells.
Eukaryotic cells are more structurally complex than prokaryotic cells.
Which of the following events takes place during Synthesis (S) phase? (usually before mitosis meiosis in reproductive organs)
nuclear division
DNA replication
RNA redistribution
cell membrane pinching
The results of meiosis are:
2 diploid identical cells
4 haploid unique cells
46 diploid unique cells
23 haploid identical cells
*Two copies of chromosomes that share similar genes, but may have different alleles are called:
sister chromatids
Chromie Homies
Replicated chromosomes
homologous chromosomes
Germ cells (cells that make egg and sperm cells) go through:
mitosis
meiosis
DNA replication
Germ cells (cells that make egg and sperm cells) go through:
mitosis
meiosis
DNA replication
All of the following create genetic variation EXCEPT..
Mutations
DNA Replication
Law of Independent Assortment
Crossing Over
When does crossing over occur?
Mitosis
Meiosis
Prophase II
Anaphase I
Chromosomes exchange genetic material during Meiosis I are called
What is a mutation?
When stem cells turn into specialized cells
A change in an individuals DNA that has no effect on genetic variation
A change in an individuals DNA that can increase genetic variation
A change in an individuals DNA that can decrease genetic variation
The diagram below represents a change that occurred in a pair of chromosomes during the formation of an egg cell. The alteration that occurred will most likely be passed on to every cell that develops from the egg cell. Why would this type of alteration result in offspring with combinations of traits that differ from those found in either parent?
It converts sex cells into body cells.
It results in the formation of diploid gametes.
. It results in new combinations of genes on each chromosome.
It changes the chromosome number of the body cells that develop from the egg cell.
A pair of identical chromosomes (one inherited from mom and one inherited from dad) are called ______________________________.
homologous chromosomes
sister chromatids
When homologous chromosomes pair up together during Meiosis I (during crossing over), they form a ______
tetrad
sister chromatids
homologous chromosomes
mitosis cells

Why is meiosis important in multicellular organisms?
Meiosis is essential for growth and repair.
Meiosis is needed for sexual reproduction and production of gamete cells.
Meiosis is NOT responsible for passing on genetic variability and beneficial mutations to the next generation.
