Mitosis and meiosis
Daughter Cells
A mother cell is divided into 2
Tetrad
A structure formed during meiosis that consists of 4 chromatids
Volume
As a cell grows, the ________ of the cell increases much more rapidly than the surface area of the cell membrane
Cleavage Furrow
At the end if cell division, animal cell will begin to pinch in. This "pinched in" are is called a _________
Homologous
Chromosomes that each have a corresponding chromosome from the opposite sex parent
Variation
Crossing over leads to _______ in the offspring
Telophase
Cytokinesis will occur during this stage
Chromosomes
DNA is packaged into ________
Nuclear Membranes
During interphase, the nucleus well defined and is surrounded by the _______
Nucleolus
During prophase, this disappears from the nucleus.
Organelles
During the G1 phase, the cell grows larger and the number of ________ is doubled
Anaphase
During this phase, the chromatins will be pulled to the opposite sides of the cell
Metaphase
During this stage of mitosis, the pairs of sister chromatids will be lined up at the center of the cell
Proteins
Each gene in a DNA molecule is the instructions
Five
How many stages are in the cell cycle
Large
If a cell grows too ____ it may have trouble moving enough food and wastes across the cell membrane.
Identical
In mitosis, daughter cell will be ________ to their mother cell.
Asexual
In this type of reproduction, a parent passes all of its genes to the offspring.
Sexual
In this type of reproduction, each parent passes down half of its genes to the offspring
Sex
Meiosis is the type of cell division that produces _____ cells
Four
Mitosis consists of how many stages
Body
Mitosis is a type of cell division that occurs in the __________ cells
Sister chromatids
Prior to cell division, the chromosomes form duplicates. These duplicates are known as
Meiosis
Reduction division in which the number of chromosomes per cell is cut in half
Gametes
Sex cells; egg and sperm
Haploid
Term meaning that a cell has only one of each kind of chromosome
Diploid
Term meaning that a cell has two of each kind of chromosomes.
Interphase
The G1, S, and G2 phases are known as
Replication
The _____ of DNA occurs during the S phase
Cytokinesis
The division of the cytoplasm
Mitosis
The division of the nucleus
Crossing over
The exchange of genetic information between segments of homologous chromosomes during prophase 1 of meiosis
Centrioles
The function of these organelles is to organize the microtubules into a spindle
Cell Cycle
The life of a cell from the time it is first formed from a dividing parent cell until its own division into two cell.
Prophase
The nuclear membrane begins to fragment and break apart during what phase.
Cell Division
The process by which cellular material is divided between two new cells.
Fertilization
The union of sperm and egg
Microtubules
These are put together to form the spindle
Cancer
This disease is caused by uncontrollable cell division
Cell Plate
This forms in plant cells to separate the two new cells from one another
Asexual Reproduction
This is the result of Mitosis in a unicellular organism
Nuclear Membrane
This reforms during telophase
Nucleolus
This returns to the nucleus during telophase
Spinole
This structure is a framework to which the chromatids will be attached
Centromere
Two sister chromatids are held together at a region called a _________
Zygote
A fertilized egg
