Phases of Meiosis
The cell prepares for meiosis at it doubles the chromosomes in the cell.
The DNA of the cell is copied in to prepare for cell division. The outcome is two identical sets of chromosomes.
What is interphase?
The organelle that is in charge of the cell and houses commands and genetic material for the cell.
What is the nucleus?
When a parent cell moves DNA and other material into position for cell division. A single cell is then divided into two identical daughter cells. This is asexual reproduction.
What is mitosis?
the homologous chromosome pair reach the poles of the cell, nuclear envelopes form and the cytokinesis follows to produce 2 cells
What is telophase?
The chromosomes go into an X formation and pair up so both pairs of chromosome 1, 2, etc, are paired up. The membrane around the nucleus dissolves, releasing the chromosomes. The mitotic spindle stretches across the cell between the centrioles as they move to opposite ends of the cell
What is prophase?
A layer of polysaccharides surrounding the plasma membrane of plants, bacteria, and fungi.
What is a cell wall?
To grow and repair cell and create exact copies of itself.
What is the purpose of mitosis?
chromosomes become visible, crossing-over occurs, the nucleolus disappears, meiotic spindle forms, the nuclear envelope disappears
What is prophase?
The chromosomes line up neatly in the center of the cell. The centrioles are at opposite ends of the cell with mitotic spindles extending from them.
What is metaphase?
An organelle found in all cells. It takes care of the energy production of the cell
What are mitochondria?
Repair, grow, and sexual reproduction
What is the purpose of meiosis?
pairs of chromosomes are referred to as bivalents are fully condensed
What is metaphase?
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The membrane surrounding the cytoplasm of a cell.
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
What is the definition of meiosis?
2 chromosomes of each bivalent separate and start moving to opposite poles of the cells the result of the action of the spindle
What is anaphase?
At each pole of the cell, a full set of chromosomes gather together. A membrane forms around each set of chromosomes to create 2 new nuclei. The single cell then pinches in the middle to form 2 separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis
What is Telophase?
A plastid that contains chlorophyll where photosynthesis takes place.
One process goes through sexual reproduction and the other goes through asexual reproduction. One has four daughter cells and the other has two.
