Vocabulary I
Specialized cells used for sexual reproduction
Gametes
A form of nuclear division that divides a diploid cell into haploid cells.
Meiosis
Is cytokinesis part of Mitosis?
No
What are the differences in the results of the cells in Mitosis and Meiosis?
Mitosis results in diploid cells, Meiosis results in haploid cells.
Two separate chromosomes; one from your mother, one from your father.
Homologous Chromosomes
A cell with two complete sets of chromosomes (2n)
Diploid cells
How many rounds of cell division does Meiosis involve?
2
What are the four main phases of Mitosis?
- Prophase - Metaphase - Anaphase - Telophase
What do Mitosis and Meiosis both produce?
Cells
The region of a chromosome where sister chromatids are joined and where spindle fibers attach.
Centromere
One half of a duplicated chromosome is a __________.
Chromatid
What are the four main phases of Meiosis?
- Prophase - Metaphase - Anaphase - Telophase
How many genetically identical daughter cells do Mitosis?
2 daughter cells
What process is involved in asexual reproduction, and which one is involved in sexual reproduction?
- Mitosis: asexual - Meiosis: sexual
- Mitosis: asexual - Meiosis: sexual
The series of events that cells go through as they grow and divide.
Cell cycle
The exchange of genetic material between homologous chromosomes during meiosis I, leading to genetic diversity.
Crossing over
When are homologous chromosomes divided?
Meiosis I
What is the purpose of Mitosis?
To produce body cells for growth and repair.
How many chromosomes do each new cell end up having in both processes for human?
Mitosis-46, Meiosis - 23
Identical copies of a chromosome connected by a centromere.
Sister chromatids
A group of four chromatids formed during meiosis by the pairing of a homologous chromosome pair.
Tetrad
What is the purpose of Meiosis?
To produce gametes for sexual reproduction
How is Interphase connected to Mitosis?
It prepares the cell to divide and provides time for the duplication of organelles and for DNA replication.
How is it different what time they both take place in an organism's life cycle?
Mitosis takes place in an organism's lifetime, Meiosis only takes place at certain times in a life cycle.
