What is mitosis?
Mitosis is the process in which two eukaryotic cells divide into two cells
Mitosis is the process in which one eukaryotic cell divides into two cells different from the parent cell
Mitosis is the process in which one eukaryotic cell divides into two cells identical to the parent cell
Why is mitosis a synonym of reproduction in some cases?
Mitosis destroys cells
In the asexual reproduction of eukaryotes, mitosis is the mechanism by which the cells that make up the new organisms are produced.
In asexual reproduction cells lose their nucleus
What is the importance of mitosis in embryonic development?
Every embryo grows from a single cell that undergoes mitosis and generates other cells that also multiply via mitosis, forming tissues and oxygen
Every embryo grows from a multi cell organism
Every embryo grows from a single cell that undergoes mitosis and generates other cells that also divide via mitosis, forming tissues and complete organs
What is the role of mitosis in the growth of pluricellular organisms?
All pluricellular organisms grow as their number of cells increases. This increase is produced by mitosis
All pluricellular organisms shrink as their number of cells increases. This increase is produced by mitosis
To kill all cells
What is the name for the disease caused by uncontrolled mitosis in pluricellular organisms?
Cancer
Parkinson's
Asthma
What is cellular regeneration?
Tissues are not able to be regenerated.
In tissue regeneration, cellular proliferation occurs via mitosis. Some tissues are able to regenerate when injured.
Cells getting energy via sunlight
What is the cell cycle?
The cell cycle is the time period that begins when the cell is created and ends when it is divided by mitosis, creating two daughter cells
The cell cycle is the time period that begins when the cell is created and ends when it is divided by mitosis, creating four daughter cells
The cell cycle is the time period that begins when the cell is created and ends when it is divided by mitosis, creating one daughter cell
Cell division happens during the entire cell cycle?
True
False
What is interphase?
Interphase is when too many cells are created
Splitting the cell membrane to create two daughter cells
During interphase, processes that prepare for cell division take place, such as the duplication of DNA and centrioles
What are the three stages of interphase?
G1, G2, and G3
G1, Synthesis, and G2
G1 G2, and Prophase
Which phase of the cell cycle takes more time?
prophase
metaphase
telophase
interphase
What events mark the beginning and the end of the first stage of interphase?
It begins with the end of the preceding cell division. It ends with the beginning of DNA replication
It begins with the beginning of DNA replication. It ends with the end of the preceding cell division.
It begins with prophase. It ends with the end of the preceding cell division.
What events mark the beginning and the end of the second stage of interphase?
it starts with the beginning of DNA replication and finishes with the end of that process
it starts with the beginning of DNA destruction and finishes with the end of that process
it starts with the beginning of metaphase and finishes with the end of that process
What events mark the beginning and the end of the third stage of interphase?
It begins with the end of DNA replication and ends with the beginning of the last period of the mitotic phase
It begins with the end of DNA replication and ends with the beginning of the first period of the mitotic phase.
It begins with the end of the membrane splitting and ends with the beginning of the first period of the mitotic phase
Does mitosis occur before or after interphase?
before
after
never
What are the stages that make up mitosis?
Mitosis is divided into four stages: prophase, metaphase, anaphase and telophase.
Mitosis is divided into three stages: prophase, anaphase and telophase.
Mitosis is divided into four stages: prophase, metaphase, anaphase and interphase.
What are centrioles?
Centrioles are phases of mitosis
Centrioles are structures that house DNA
Centrioles are tiny cylindrical structures made of nine microtubule triplets.
In which types of cells are centrioles found?
plants
animals
none
What are the main events of the first stage of mitosis?
It starts with the beginning of DNA replication and finishes with the end of that process.
the splitting of the cell wall, creation of new cells
the migration of each centriole pair to opposite poles, the formation of spindle fibers between the two centriole pairs
What is the mitotic apparatus?
The mitotic apparatus is a set of aster fibers and spindle fibers
Interphase is the phase preceding mitotic division.
Cell division normally occurs during the mitotic phase of the cell cycle.
