Cell Division

Mphase

100

The last phase of Mitosis is Cytokinesis. Describe what happens during this phase.

The 2 daughter cells begin to pull apart, the division of the cytoplasm takes place

200

Anaphase is the 3rd phase of Mitosis. What occurs during this phase? you must use the word centromere and spindle fiber in your answer

The centrioles have attached with their spindle fibers to the centromere (center of chromosome) and have pulled the chromosomes apart to opposite ends of the cell.

300

Metaphase is the second phase in Mitosis. What occurs during this phase?

The chromosomes line up down the middle (equator) of the cell

400

Telophase is at the end of Mitosis just before Cytokinesis. What occurs during Telophase? You must use the word Nucleus in your answer.

The two daughter cells begin to pull apart. The nuclei have formed again containing the DNA

500

Interphase is the longest phase of Mitosis. What occurs during this phase. You must name the different phases to get credit.

G₁ Phase- The cell begins to grow in size, increased number of organelles

S phase- DNA Synthesis

G₂ phase- Continued growth of the cell

Cancer

100

What causes a cell to be considered "cancer"?

You must use the word regulate in your answer

The cancer cell can no longer regulate the cell cycle. The cell divides on its own and does not answer to the cyclin protein.

200

What does Cyclin do?

It is a protein that turns on or turns off the cell cycle(division)

300

What are some treatment options for cancer?

Radiation Therapy, Surgery, Chemotherapy

400

A mass of cancer cells built up in one spot is called a

Tumor

500

In the human body, some cells divide frequently and some cells rarely divide. Give an example of some cells that divide quickly, an example of cells that would rarely divide.

Which group would cancer cells belong to?

Skin cells, stomach cells, somatic cells will divide quickly to replace damaged cells

Nerve cells, brain cells will rarely divide if ever.

Cancer cells divide quickly since they can no longer regulate their cell cycles.

Cell Division

What are the two types of Cellular reproduction

Asexual and Sexual

200

Place the phases of mitosis in order.

include interphase in your answer

Interphase

Prophase

Metaphase

Anaphase

Telophase

Cytokinesis

300

What is one advantage to sexual reproduction and what is one advantage to asexual reproduction

sexual reproduction = genetic diversity

asexual reproduction = faster reproduction

400

What type of reproduction do our cells (human) undergo?

sexual reproduction -gametes

asexual reproduction- somatic cells (skin, liver, stomach etc)

500

Many Eukaryotic cells can be grown in tissue cultures in the laboratory. Suppose you have two tissue cultures, one in G₁ phase and one in the S phase. How would you determine which culture was in G₁ and which was in S phase?

G₁ = growth= Look for increased numbers of organelles/ growth in size

S phase= DNA being duplicated

Last ChapterCell Organelle

100

What organelle is known as the Power House of the cell

it provides the cell with energy ATP

Mitochondria

200

What organelle is known as the Brain of the cell. It is the location of DNA in a eukaryotic cell

Nucleus

300

The difference between a eukaryotic cell and a prokaryotic cell is that Eukaryotic cells possess a 

nucleus

400

This semi-permiable organelle is responsible for allow certain things into the cell and keeping certain things out

Cell membrane

500

List 3 organelles that a plant cell possess that animal cells do not.

Chloroplast

Cell Wall

Central Vacuole
