The Basics
The purpose of meiosis is
production of gametes
Which phase occupies most of the cell's time?
S Phase
A structure found during animal cell mitosis that is not found during plant cell mitosis is a
cleavage furrow
The process of mitosis insures equal distribution to the new cells of the
chromosomes
Two chromatids joined at the centromere are called
sisters
The purpose of mitosis is
growth, repair of injury, replacement of worn out cells
What is occurring in the G1 and G2 phases?
Growth
A structure found during plant cell mitosis that is not found during animal cell mitosis is a
cell plate
By which process are two daughter nuclei formed that are identical to each other and to the original nucleus?
mitosis
In the mitosis phase, what is dividing?
Nucleus
After mitotic cell division, the number of chromosomes in each daughter cell as compared to the parent cell is
the same
In which phase does chromosome replication occur?
S Phase
prokaryotes reproduce by a type of cell division called what?
Binary fission
By which process are two daughter nuclei formed that are NOT identical to each other and to the original nucleus?
meiosis I
What is the name of a fertilized human egg
zygote
After meiotic cell division, the number of chromosomes in each daughter cell as compared to the parent cell is
Half
The nuclear envelope and nucleolus disperse during what phase of mitosis
Prophase
A cell that is undergoing cellular division is examined with a microscope. The cell is most likely an animal cell if the
centrioles migrate
What is the correct order for the phases of mitosis?
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
Each pair of chromatids is attached at an area called the
centromere
Meiosis would only be found in what organs
ovaries & testes
In antaphase I what is separating
Tretrads/Homologous Chromosomes
In an attempt to reduce the population of starfish feeding on clams, fishermen cut into pieces and threw overboard any starfish that they caught. The following season there were more starfish than before. This increase in population was most likely the result of
Regeneration
What is the correct order for the phases of meiosis?
Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis, Prophase II, Metaphase II, Anaphase II, Telophase II, Cytokinesis
What would result if cytoplasmic division did not accompany mitosis?
one cell with two nuclei
