Cell Division and mitosis Flashcards
Cells only come from other ________________
cells
All organisms are made of _______________
cells
Cells are the basic units of _____________and __________ in all living things.
structure and function
Why is it necessary to create more cells? (Name 3 reasons)
1.to grow and develop
2. repair and replace damaged cells
3. replace old cells that die
the continuous process of a cell dividing and creating two new cells
cell division
The life cycle of a eukaryotic cell
cell cycle
The cell cycle is the life cycle of a _________________ cell
eukaryotic
The cell cycle includes the division of the _______________, the ____________________, and the creation of ____________ new cells.
nucleus, cytoplasm, 2
Do prokaryotic cells contain a nucleus?
no
What do we call the coiled structure made of DNA and protein that is present during cell division and visible with a light microscope?
chromosomes
Chromosomes are the coiled structure made of ____________________ and _________________ that is present during cell division and visible with a light microscope.
DNA and protein
What are the four phases of mitosis, in the correct order?
prophase, metaphase, anaphase, and telophase
In what phase of mitosis are chromosomes moving toward opposite sides of the cell?
anaphase
What is cytokinesis?
A phase of mitosis when the cytoplasm pinches in half and each daughter cell has an identical set of duplicate chromosomes.
What are the two main parts of the cell cycle?
mitosis and interphase
division of the nucleus that separates chromosomes equally
mitosis
the stage when the cell does not go through mitosis- it prepares for cell division
interphase
The cell cycle ends with __________________.
cytokinesis
The original cell is called a _______________ cell and the two cells that result are called _____________________ cells.
parent, daughter
What type of cell division results in daughter cells that contain half the DNA of the parent cell?
meiosis
sex cells that contain the DNA of the parent cell
gametes
the fertilized egg that results from the union of the egg and sperm.
zygote
a cell that contains a full set of DNA
zygote
