What happens during metaphase?
The chromosomes line up along the middle of the cell.
The cell actually splits in two during this
phase
Cytokinesis
After the chromosomes line up in the middle of the cell, what happens
next?
The spindle fibers pull the chromatids apart
and move them to opposite ends of the
cell. This is anaphase.
In telophase, what two things happen
that involve the DNA?
The DNA uncoils and returns to chromatin form. New nuclear
membranes are formed around the
DNA.
What happens during prophase?
The DNA condenses, the nuclear
membrane dissolves, and spindle fibers begin to form at
opposite ends of the cell
A cell spends most of its life in this phase.
Interphase
What two things happen during Interphase that
prepare the cell for division?
The cell grows and the DNA is replicated.
What would happen if a cell did not grow before
dividing?
It would get smaller and smaller at each
division, until it could no longer function.
What is the main thing that is
happening during the four stages of
mitosis?
The nucleus and its DNA are dividing.
List, in order, the six stages of the
cell cycle.
Interphase, Prophase, Metaphase,
Anaphase, Telophase, Cytokinesis
In osmosis and diffusion, molecules
always move from an area of ______
concentration to an area of ______ concentration.
High; low
What is equilibrium?
Equilibrium is when the concentration of a substance is the same everywhere (the substance is evenly spread out.)
A carrot cell is placed in a solution of salt water. What will
happen?
Water will leave the cell, due to osmosis. The central vacuole will shrink and the cell will collapse.
A skin cell is placed in a solution of pure water. What will
happen?
Water will enter the cell, due to osmosis. The cell will swell and may eventually burst.
In order for a large molecule (such as glucose) to enter a
cell, the cell must use _____________.
Energy
The variable in an experiment that is
changed by the scientist is called the
_____________ variable.
independent
The variable in an experiment that is
measured or observed by the
scientist is called the _______________
variable.
dependent
Andy wants to know if going to bed an hour early the night before
will help him get a better grade on tests.
What is the independent
variable?
The time he goes to bed.
Alice wants to know if warm water freezes
faster than cold water. What is the
dependent variable?
How long it takes for the water to freeze.
Restate this hypothesis in the correct format.
Mixing seaweed into the soil causes plants
to grow taller.
If seaweed is added to the soil, then plants will
grow taller because seaweed contains plant
nutrients.
Why is it a problem if a cell gets too big?
The volume is too big for the size of the cell membrane and the cell can’t get enough materials.
In what section of a lab report do you state whether the hypothesis was
supported or not?
In the conclusion
Why doesn’t the statement “My
results showed an increase in
temperature.” belong in a lab report?
You shouldn’t use words like “I”, or
“my” in a lab report.
Which of the following does not belong a lab
report: Results, Purpose, Opinion,
Hypothesis
Opinion
