Cancer cause what with cell growth
uncontrollable cell growth
A single cell that started life and progressed through a developmental stage is called an
Embryo
What are the two types of stem cells
Adult stem cells
Embryonic stem cells
Why does having more surface area than volume matter?
because it is easier to get more nutrients and to export waste
What is cytokinesis?
it is the division of the cytoplasm. occurs during telophase
Why does uncontrollable cell growth occur?
cancer cells do not respond to signals that communicate the cell growth
The longer the cells progress the more _____ they are
differentiated
what does pluripotent mean?
The cells can develop into any cells other than the tissues surrounding the embryo

Give an analogy of when volume gets bigger then surface area. ex: Our class has a library and we all are good for each getting a book but then the entire upper school uses it then the wait time for books becomes longer and the books are more scarce
i will grade on my opinion
Which type of cell has a cell plate
plant cell
What causes cancer?
defects in genes that regulate cell growth and division
What cells are totipotent and can differentiate into any type of cell.
Only the fertilized egg and the cells produced by the first few cell divisions of embryonic development.
a hollow ball of cells with a cluster of cells on the inside is known as the
inner cell mass
