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
