|
The process by which a cell divides into two new daughter cells is called
|
Cell division
|
|
|
The production of genetically identical offspring from a single parent is known as
|
Asexual reproduction
|
|
|
Offspring produced by two parents were they inherit some genetic information from both
|
Sexual reproduction
|
|
|
What are some of the difficulties a cell faces as it increases in size
|
The larger the cell becomes the more demand the cell places on acid DNA in the less efficient in moving nutrients and waste materials across the cell membrane
|
|
|
Chromosomes
|
Genetic information bundled into packages of DNA
|
|
|
Chromatin
|
Complex of chromosome in protein
|
|
|
What is the role of chromosomes in cell division
|
Chromosomes make it possible to separate DNA precisely during
|
|
|
What Events of a cell cycle
|
A cell grows prepares for division and divides to form two daughter cells
|
|
|
Interphase
|
Life of a cell as one cell division after another separated by an in between. Of growth
|
|
|
What are the four phases of mitosis
|
Prophase metaphase anaphase telophase
|
|
|
What are the two main stages of cell division in eukaryotes
|
mitosis cytokinesis
|
|
|
Mitosis
|
First stage of the process of cell division
|
|
|
Cytokinesis
|
Second stage of the of the division of the cytoplasm it begins while mitosis is still taking place
|
|
|
Prophase
|
First phase of mitosis genetic material inside the nucleus condenses and the duplicated chromosomes become visible
|
|
|
Centromere
|
Region of a chromosome where the two sister chromatids attach
|
|
|
Chromatid
|
1 of 2 identical sister parts of a duplicated chromosome
|
|
|
Centriole
|
Tiny paired structures located in the centrosome
|
|
|
Metaphase
|
The second stage of mitosis in which the chromosomes line up across the center of the cell
|
|
|
Anaphase
|
Third stage in mitosis in which the chromosomes separate and move to opposite ends of the cell
|
|
|
telophase
|
Fourth stage of mitosis in which the individual chromosomes begin to spread out into a tangle chromaton
|
|
|
Huh how do daughter cells split apart after mitosis
|
Cytokinesis completes the process of cell division this place in one cell into two
|
|
|
Cyclin
|
Is a protein that regulates the cell cycle
|
|
|
what are that to regulatory proteins
|
Internal regulators and out or regulators external regulators
|
|
|
G growth factors
|
Stimulate the growth and division of cells external regulatory proteins is the group made up of the growth factors
|
|
|
Apoptosis
|
Process of programmed cell death
|
|
|
Cancer
|
A disorder in which the body cells lose the ability to control growth
|
|
|
Tumor
|
Mass of cancer cells
|
|
|
How do cancer cells different from other cells
|
Cancer cells do not respond to the signals that regulate the growth of most cells as a result the cells divide uncontrollably
|
|
|
Embryo
|
When living things pastor to a development stage
|
|
|
Differentation
|
The process by which cells become specialized
|
|
|
Totipotent
|
A cell that can literally do everything
|
|
|
blastocyst
|
Hollow ball of cells with a cluster of cells known as the inner cell mass
|
|
|
Pluripotent
|
Can develop into most but not all of the body's cell types
|
|
|
Stem cells
|
the unspecialized cells from which differentiated cells developed are known as stem cells
|
|
|
Multipotent
|
They can develop into many different types of differentiation cell s
|
|
|
What are the possible benefits and issues associated with stem cell research
|
Stem cells offer the potential benefit of using undifferentiated cells to repair or replace badly damaged cells and tissues
|
