Cell Growth, Division, and Reproduction

Question 1

Cell Division

Answer 1

the process by which a cell divides into two daughter cells

Question 2

Information Overload

Answer 2

As a cell increases in size, the DNA stays the same, so if a cell grew too big, an information overload occurs

Question 3

What solves the “information overload” problem?

Answer 3

The replication of DNA before cell division

Question 4

What is another way that cell division solves “information overload”

Answer 4

By INCREASING the surface area to volume ratio (SA-to-V)

Question 5

Reproduction

Answer 5

the formation of new individuals and is also one of the most important characteristics of life

Question 6

How do unicellular organisms reproduce?

Answer 6

Cell division

Question 7

What are the two types of reproduction?

Answer 7

Asexual and sexual

Question 8

Asexual reproduction

Answer 8

the production of genetically identical offspring from a single parent

Question 9

What organisms reproduce asexually?

Answer 9

Bacterium, unicellular organisms, some multicellular organisms, hydras, and some plants

Question 10

Sexual Reproduction

Answer 10

offspring produced by the fusion of special reproductive cells formed by each of the 2 parents

Question 11

Where do the offspring of organisms produced during sexual reproduction get their genetic information from?

Answer 11

from both parents

Question 12

What organisms perform sexual reproduction

Answer 12

most animals and plants and some unicellular organisms

Question 13

Mitosis for cells can also be known as

Answer 13

asexual reproduction

Question 14

Why do cells divide

Answer 14

1) B/c the DNA of a cell can only control up to a certain amount of organelles before it loses control
2) Bc a large cell is less efficient with transporting nutrients and waste materials out of the cell
3) Bc as a cell grows there is a higher amount of waste, proteins, nutrients, etc

Question 15

What represents the surface area of a cell

Answer 15

cell membrane

Question 16

What represents the volume of a cell

Answer 16

cytoplasm

Question 17

An asexual parent produces a

Answer 17

clone

Question 18

As a cell’s size increases, the ratio of its surface area to volume ______

Answer 18

decreases

Question 19

Why is the surface area to volume ratio of a cell important/

Answer 19

Bc it shows how much surface area is present to be able to transport the components in the volume of the cell

Question 20

When dimensions double, surface area multiplies by

Answer 20

4

Question 21

When dimensions double, volume multiplies by

Answer 21

8

Question 22

What are the disadvantages of asexual reproduction?

Answer 22

1) Lack of biodiversity can kill off species if the environment changes

Question 23

What are the advantages of asexual reproduction?

Answer 23

1) faster
2) required less energy (to mate, etc.)
3) less mutations so strive in the same way (thrive in the same environment)

Question 24

What are the disadvantages of sexual reproduction?

Answer 24

1) Process of finding a mate and the growth and development of the offspring take a long time

Question 25

What are the advantages of sexual reproduction?

Answer 25

1) Higher chance of mutation (which can be beneficial) which helps evolution (adapt to a changing environment)
2) Provides genetic diversity — if environment changes, organism might still have characteristics to survive

Question 26

What is one organisms that reproduces sexually and asexually

Answer 26

yeasts

Question 27

yeast is a ___-_____ ________

Answer 27

single-celled eukaryote

Question 28

Why do yeasts reproduce sexually and asexually

Answer 28

they usually reproduce asexually but when needed they reproduce sexually
