When is the DNA replicated?
S phase (synthesis)
What is the longest phase of the cell life?
interphase
What happens to the chromosomes during metaphase?
Chromosomes lineup in the middle and spindle fibers attach to the centromere.
What happens during telophase?
Chromosomes unravel, the nuclear membrane reforms around the two new nuclei, the cell fully divides.
What are chromosomes?
DNA that is organized into condensed units.
Mitosis, results in two identical _____ ____?
daughter cells
What is the longest phase of mitosis?
prophase
What is the more formal name for the area where the chromosomes line up?
metaphase plate
When the cell finishes dividing, how many centrioles will each new daughter cell have?
1
How many chromosomes do humans have?
46
_______ is an uncontrolled cell growth?
Cancer.
Which organelle(s) helps with cell division and rotates to the poles during prophase?
centriole
What happens during anaphase?
The chromosomes split at the centromere and the spindle fibers separate the sister chromatids.
Cleft in the cell membrane/cytoplasm that will eventually fully separate.
cleavage furrow
Identify A
Centromere
What is programmed cell death?
apoptosis
What are two things associated with Interphase?
What is DNA replication and growth.
Cells don't lose the number of chromosomes in their daughter cells because they copy and pair up. This means they are ______.
diploid
________ is action of the final separation into two cells by splitting the cytoplasm.
Cytokinesis
Identify B
Chromatid
The major purpose of mitosis is for growth and to ____ worn out cells.
repair
DAILY DOUBLE!!!!
What are three things that happen during prophase?
1) DNA condenses to chromosomes
2) Nuclear membrane dissolves
3) Centrioles migrate to the poles
What are the spindle fibers made of?
microtubules/cytoskeleton
In which direction does the final splitting of a PLANT cell happen?
inside out
