Asexual Reproduction And Cancer

Question 1

What is monoculture?

Answer 1

The cultivation of one plant in a large area.

Question 2

Does Asexual Reproduction use monoculture?

Answer 2

Yes, It uses the benefits and risks that monoculture has to offer.

Question 3

What is vegetation propagation?

Answer 3

The process of cloning plants while making farming more reliable.

Question 4

What may threaten monoculture?

Answer 4

Changes in the environment threaten may threaten entire monoculture because of the lack of variability (ex. New pest)

Question 5

Can organisms reproduce both asexually and sexually?

Answer 5

Yes

Question 6

What’s an example of an organism that reproduces both asexually and sexually?

Answer 6

Yeast

Question 7

Binary fission

Answer 7

chromosomes replicate and cell splits into two new cells of equal size.

Question 8

Where is binary fission common?

Answer 8

Bacteria and protists

Question 9

Spore formation

Answer 9

chromosomes replicate and are surrounded by a tough outer cote. Then, the spore divides to form a new fungus or plant

Question 10

What is buddding?

Answer 10

nucleus and cytoplasm of a cell are duplicated but the the daughter cell- called a bud- is smaller than the parent- it then pinches off to become a new individual

Question 11

What is vegetative propagation?

Answer 11

some plants
produce new individuals that are
initially attached to parent and then
separate

Question 12

What are some methods of vegetative propagation?

Answer 12

cuttings and runners (horizontal, above-ground stems)

Question 13

What is regeneration?

Answer 13

development of a new

animal from its body parts

Question 14

Do cancer cells perform any useful functions?

Answer 14

No, cancer cells don’t perform helpful/useful functions.

Question 15

How do organisms usually get cancer cells?

Answer 15

Organisms get cancer cells from mutations in genes that produce proteins involved in the cell cycle.

Question 16

What does radiation do?

Answer 16

It targets specific cells and destroys them.

Question 17

Cancer can result in what?

Answer 17

tumors

Question 18

What do tumors look like

Answer 18

clumps of cells normally on the skin that grow into the veins

Question 19

What is the trend in differences in cancerous cells and normal cells?

Answer 19

Cancer cells have less total cells in each cell cycle process while normal cells have more.

Question 20

What does radiation do?

Answer 20

It targets specific cells and destroys them.

Question 21

What does the immune system do?

Answer 21

It helps detect the early developments of cancer cells and destroys them. However, sometimes cancer cells are able to avoid being detected.

Question 22

What can tumors do?

Answer 22

Deprive normal cells of nutrients

Question 23

What does Chemotherapy do?

Answer 23

Chemotherapeutic drugs interfere with the duplication of DNA. Since continuously dividing cells duplicate DNA frequently it is especially toxic to them.

Question 24

Are normal cells effected by chemotherapy?

Answer 24

No, only rapidly dividing cells are.

Question 25

What are some rapidly dividing cells?

Answer 25

Hair cells, Bone marrow cells (causes blood problems if they deplete), and cells that line the digestive track (causes nausea if they deplete)

Question 26

What do offspring have?

Answer 26

Offspring have some organelles and

cytoplasm of parent cell

Question 27

What part of an offspring is identical to that of the parent?

Answer 27

Genetic material of offspring is

identical to that of parent
