What are the 4 stages of mitosis: Prophase, Metaphase, Anaphase, and Telophase
100
The difference between "internal" and "external"
What is that internal is inside; external is outside
100
Cells without a nucleus (PROKARYOTIC cells) reproduce this way
What is by BINARY FISSION
100
The way our bodies are organized, from smallest to biggest
What is: cell, tissue, organ, organ systems
200
the stage of the cell cycle during which DNA is copied
What is synthesis
200
What happens during prophase
What is that DNA coils itself into chromosomes
200
During normal cell growth, when a cell physically "bumps" agianst another cell, this happens
What is the cell stops growing.
200
Some Eukaryotic cells also reproduce asexually, through a process known as this
What is mitosis (or mitotic reproduction)
200
The process of cells becoming specialized is known as _________
What is cell differentiation
300
What happens in Gap 1
Cell grows and does its job/fuction
300
The stage when chromosomes line up in the Middle of the cell
What is Metaphase
300
The definition of "apoptosis"
What is planned cell death
300
The three types of Mitotic reproduction
What are budding, fragmentation, and vegetative reproduction
300
Why stem cells are important
What is because they can turn into anything, and thus have the potential to cure a large number of diseases and disabilities
400
The stage of the cell cycle during which the one cell has two copies of DNA in its one nucleus
What is Gap 2
400
The stage during which spindle fibers pull Apart the chromosomes
What is Anaphase
400
Out-of-control cell growth is called ____________
What is cancer
400
Name two advantages of asexual reproduction
What are (any 2): No need to waste time/energy finding a mate. No genetic changes - so you remain adapted to your environment. Greater number of offspring (1 parent --> 2 offspring)
400
The three classifications (potentcies) of stem cells
What are totipotent, pluripotent, and multipotent
500
Why different cells have different life spans
Those with more wear-and-tear (like skin cells or cells inour intestinal lining) replenish faster than other cells with less wear-and-tear (like nerve cells)
500
The end result of Mitosis
What is 2 daughter cells that are identical
500
A malignant tumor is this
What is a "bad" tumor - whose cells can break away and grow in other parts of the body, spreading cancer
500
A disadvantage of asexual reproduction
What is that the organism can not evolve or adapt to a changing environment.
