Mitosis and meiosis
Cell cycle/ stages of mitosis
Cancer cells
Stem cells and apoptosis
Genetic stuff (meiosis)
100
The nucleus divides, and the chromosomes separate into two nuclei
What is mitosis?
100
The phase in the cell cycle where cells grow and carry out normal cell processes,and DNA is replicated.
What is interphase
100
The uncontrolled growth of cells
What is cancer?
100
Unspecialized cells that have the potential to develop into specialized cells
What are stem cells?
100
Telophase 1 ( meiosis)
What is the final stage of meiosis 1?
200
A kind of division that reduces the number of chromosomes by half through the separation of homologous chromosomes
What is meiosis
200
In this stage chromosomes attach to the mitotic spindle and align along the equator of the cell
What is metaphase
200
How cancer kills an organism
What is the over crowding of normal cells?
200
Programmed cell death ( like cell suicide)
What is apoptosis
200
Is created by the crossing over and fertilization ( when two haploid a combine)
What is genetic diversity?
300
What meiosis is for
What is sexual reproduction?
300
Microtubules shorten, and chromosomes move to opposite poles of the cell
What is anaphase
300
Substances known to cause cancer
What are carcinogens?
300
Two types of stem cells
What are embryonic stem cells and adult stem cells?
300
Because the ________ cells are different, meiosis results in genetic variation
What is daughter?
400
Is for growth , repair, and asexual reproduction
What is mitosis
400
The phase where the nuclear membrane disintegrates, the nucleolus disappears and the mitotic spindle begins to form
What is prophase
400
People might inherit _________ from their parents which increases their risk for cancer
What are DNA mutations?
400
Occurs during embryo development and to cells that are damaged beyond repair
What is apoptosis
400
The DNA on the chromosomes is is arranged in sections called _______
What are genes
500
Results in 4 daughter gametes
What is meiosis?
500
The phase where the cell plate forms to divide the two daughter cells... It's to final stage of mitosis
What is cytokinesis
500
______ people have a higher risk of getting cancer?
What are older?
500
Causes leaves to fall off trees in autumn
What is apoptosis?
500
Living things have thousands of _________ (hint: it's not cells)
What is genes?
