Cell Growth, Division, and Reproduction
The Process of Cell Division 1
The Process of Cell Division 2
Regulating the Cell Cycle
Cell Differentiation
100
The process in which a cell divides into two new identical daughter cells
What is cell division?
100
Threadlike structures within the nucleus that contain genetic information that is passed on from one generation to the next
What are chromosomes?
100
Series of events in which a cell grows, prepares for division, and divides to form two daughter cells
What is the Cell Cycle?
100
One of a group of external regulatory proteins that stimulate the growth and division of cells
What are Growth Factors?
100
The developing stage of a multicellular organism
What is an Embryo?
200
What is difference between sexual and asexual reproduction?
Asexual= Single parent produces genetically identical offspring
Sexual= 2 parents combine to form unique offspring.
200
Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
What is Chromatin?
200
Division of the cytoplasm to form two separate daughter cells
What is Cytokinesis?
200
The process of programmed cell death.
What is Apoptosis?
200
Process in which cells become specialized in structure and function
What is differentiation?

What is the surface area to volume ratio of a 3cm x 3cm x 3cm cube.
Surface Area = 54cm2 (3 x 3 x 6)
Volume = 27cm3 (33)
Ration = 2:1
300
The longest period of the cell cycle, where the stages G1, S, and G2 take place
What is Interphase?
300
Part of eukaryotic cell division during which the cell nucleus divides
What is Mitosis?
300
One of a family of proteins that regulates the timing of the cell cycle in eukaryotic cells
What are Cyclins?
300
What is the difference between totipotent, pluripotent, and multipotent stem cells?
Totipotent- can develop into any cell type
Pluripotent- can develop into most cell types
Multipotent- can develop into some cell types
400
What are the three main problems of size for cells.
Surface area to volume ratio, Traffic Problems, Information Overload.
400
What phase of Mitosis is the cell currently undergoing?
Metaphase
400
What are the 4 phases of Mitosis?
Prophase --> Metaphase -->Anaphase--> Telophase
400
What masses are produced when cells lose control of their growth and division?
Tumors

What makes Stem Cells special?
They are unspecialized cells that can develop into one or more types of specialized cells.
500
Give 2 examples of how organisms asexually reproduce.
Examples include, binary fission (like in bacteria), Budding (like in hydras), and Vegetative Propagation (some plants).
500
What phase of Mitosis is the cell currently undergoing?
Anaphase
500
What phase of Mitosis is the cell currently undergoing?
Telophase

In your own words, what is cancer? (No Books)
Answers will vary...
Should be something like "Cancer is a disorder where cells behave abnormally, they grow and divide uncontrollably causing tumors, "

Shinya Yamanaka, a Japanese stem cell researcher, converted human fibroblasts, cells that make proteins in skin, into induced pluripotent stem cells.
Why is this a big deal?
You can potentially take a specialized cell, change it into a stem cell, then take that stem cell and convert it back into a different specialized cell.
(This can potentially replace embryonic stem cells)
