Chapter 5 Cell Growth and Division
Terms in this set (34)
a regular pattern of growth, DNA replication, and cell division
cell growth and normal functions
division of the cell nucleus
division of the cell cytoplasm
Some cells are unlikely to divide
one long continuous thread of DNA that consists of numerous genes along with regulatory information
DNA wraps around proteins that condense it
DNA plus proteins
One half of a duplicated chromosome
Sister chromatids are held together
protect DNA and do not include genes
prepares the cell to divide.
the DNA is duplicated.
chromosomes condense and spindle fibers form
chromosomes line up in the middle of the cell.
sister chromatids separate to opposite sides of the cell
the new nuclei form and chromosomes begin to uncoil
are proteins that stimulate cell division
is programmed cell death
cells form disorganized clumps called tumors
remain clustered and can be removed.
metastasize, or break away, and can form more tumors.
are substances known to promote cancer
is the creation of offspring from a single parent
produces two daughter cells genetically identical to the parent cell. Occurs inprokaryotes
forms a new organism from a small projection growing on the surface of the parent
is the splitting of the parent into pieces that each grow into a new organism
forms a new plant from the modification of a stem or underground structure on the parent plant
are groups of cells that perform a similar function
are groups of tissues that perform a specific or related function
are groups of organs that carry out similar functions
Cells develop into their mature forms through the process of
divide and renew themselves
remain undifferentiated in form
develop into a variety of specialized cell types
