Mitosis - ✔✔The process by which cells divide, creating two identical
daughter cells.
Prophase - ✔✔The first phase of mitosis in which chromosomes condense
and become visible.
Anaphase - ✔✔The third stage of mitosis in which chromosome pairs are
split up equally and pulled to separate sides of the cell.
Telophase - ✔✔The fourth (and last) stage of mitosis in which
chromosomes bunch up at either end of the cell and begin to unravel into
their original state.
Cytokinesis - ✔✔When the cytoplasm divides after mitosis, creating two
identical cells.
Metaphase - ✔✔The second stage of mitosis in which chromosomes line
up in pairs along the center of the cell.
,Why does an onion root tip have more cells undergoing mitosis than an
elodea leaf? - ✔✔The leaf's job is to perform photosynthesis, so it does not
need to grow. The onion root tip's function is to grow, so many of the cells
are dividing.
What is the purpose of mitosis? - ✔✔Growth and repair.
Normal cells are in mitosis for _____% of their life and in interphase for
____% of their life. - ✔✔10, 90
Chromosome - ✔✔DNA and proteins coiled around each other found in the
nucleus of the cell.
How many chromosomes do humans have? - ✔✔46
How are cancerous cells different from normal cells? - ✔✔Cancerous cells
spend more time in mitosis than interphase, have a higher density in a
given area, have many different sizes and shapes, disorganized DNA, an
abnormal number of chromosomes, a larger and darker nucleus, no clear
boundaries, clump together in a tumor, do not have contact inhibition, and
undergo mitosis without a purpose.
Do cancerous cells or normal cells spend less time in mitosis and
interphase? Why? - ✔✔Cancerous cells spend less time in mitosis and
, interphase because oncogenes have accelerated their cell cycle or there
are no tumor suppressor genes.
Why is an increased rate of mitosis in cancerous cells different than an
increased rate of mitosis in an onion root tip? - ✔✔In an onion root tip, the
root's purpose is to continue to grow to seek water and nutrients. This kind
of growth is planned and necessary for the plant's survival, so the
increased rate of mitosis makes sense. In cancerous cells, there is no
purpose for the mitosis. It is not planned or necessary.
Do cancerous cells or normal cells have a higher density in a given space?
Why? - ✔✔Cancerous cells increase exponentially in cell density, so there
are many more of them packed into a given space. Normal cells recognize
when a space has been filled and stop dividing (contact inhibition), but
cancerous cells have lost their ability to receive the signal that the space is
filled, so they continue to divide.
Apoptosis - ✔✔Programmed cell death that eliminates unnecessary cells
during development and removes unhealthy/damaged cells.
Explain the relationship between normal cell division and apoptosis. - ✔✔In
normal cells, when there is DNA damage that the cell cannot fix, it
