Cell Division
____ is vital for the reproduction of organisms and the growth and development of multicellular organisms
What is Cell Division?
The cell cycle begins with ______, during which the cell grows, carries out normal cellular functions, and replicates its DNA.
What is interphase?
During cell division, there are two main parts: mitosis and ______.
What is cytokinesis?
This part of mitosis is where chromosomes decondense, nuclear envelopes reform, and the mitotic spindle disassembles.
What is telophase?
Proper ______ of the cell cycle is crucial for preventing mutations, genomic instability, and diseases such as cancer.
What is regulation?
_____ involves the creation of genetically identical offspring from a single parent
What is asexual reproduction?
This is when the cell grows bigger.
What is G1 phase?
The mitotic phase includes ____, during which the nucleus divides, and cytokinesis, where the cytoplasm divides, resulting in two daughter cells.
What is mitosis?
The division of the cytoplasm and organelles between the two daughter cells, completing the cell cycle.
What is cytokinesis?
Mitosis helps maintain a constant number of cells in an organism, contributing to the overall balance and stability of the body's internal environment.
What is homeostasis?
____ involves the fusion of gametes from two parents, resulting in genetically diverse offspring
What is sexual reproduction?
This is where the cell makes a copy of its DNA.
What is S phase?
This part of mitosis is where chromosomes condense, the nuclear envelope breaks down, and the mitotic spindle forms.
What is prophase?
In animal cells, cytokinesis involves the formation of a __________, which pinches the cell in two.
What is a cleavage furrow?
_____ is characterized by uncontrolled cell division and growth, often resulting from mutations in genes that regulate the cell cycle.
What is cancer?
Asexual reproduction typically involves ______
What is mitosis?
This is where the cell gets ready for the next step, mitosis.
What is G2 phase?
This part of mitosis is where chromosomes align at the metaphase plate, attached to spindle fibers.
What is metaphase?
In plant cells, a ________ forms between the daughter nuclei, eventually developing into a new cell wall.
What is a cell plate?
Errors during mitosis can lead to chromosomal abnormalities, such as aneuploidy, which can cause genetic disorders such as _____.
What is Down syndrome?
Sexual reproduction involves _____ followed by fertilization
What is meiosis?
This is when the cell does three main things: grows bigger, does its usual jobs, and makes a copy of its DNA.
What is Interphase?
This part of mitosis is where sister chromatids separate and move to opposite poles of the cell.
What is anaphase?
____ are control mechanisms that ensure the cell cycle progresses accurately and can halt the cycle if necessary to repair DNA damage or other abnormalities.
What are checkpoints?
_____ and _____ regulate the progression through the cell cycle by activating key proteins involved in cell cycle transitions.
What are cyclins and cyclin-dependent kinases (CDKs)?
