meiosis, cell cycle and asexual reproduction part 1

Question 1

explain G1 in interphase

Answer 1

the cell increases in size and synthesis new organelles

Question 2

explain G2 in interphase

Answer 2

the cell continues to grow and it produces proteins needed for cell division

Question 3

explain S in interphase

Answer 3

the cell’s DNA is replicated and is ready for cell division

Question 4

a cycle of growth, developement, and division, that most cells in an organism go through

Answer 4

cell cycle

Question 5

four reasons why the cell cycle is important

Answer 5

growth, tissue repair, asexual reproduction, the formation of gametes

Question 6

what moves the chromatids during mitosis

Answer 6

spindle fibers

where are the chromatids produced

Answer 7

centrioles

Answer 10

prophase

Question 11

chromosomes line up in the middle of the cell

Answer 11

metaphase

Question 12

chromosomes separate and move to opposite ends of the cell

Answer 12

anaphase

Question 13

chromosomes move to opposite ends of the cell and two nuclei are formed

Answer 13

telophase

Question 14

how many daughter cells are created from mitosis

Answer 14

two daughter cells

Question 15

what is the DNA comparison between the parent cell and the two daughter cells created during mitosis

Answer 15

Question 16

what are the three parts of the cell cycle

Answer 16

cytokinesis, interphase, mitosis,

Question 17

division of the cytoplasm

Answer 17

cytokinesis

Question 18

The cell grows, performs its normal functions, and prepares for division

Answer 18

interphase

Question 19

the process in which the nucleus and its contents divide

Question 26

what are the seven different types of asexual reproduction

Answer 26

binary fission, budding, cloning, vegetative reproduction, regeneration, spore formation, and parthenogenesis

Question 27

list the qualities of sexual reproduction

Answer 27

involves two parents, offspring is a genetic mix of both parents, involves specialized sex cells, it's slow.

Question 28

what type of asexual reproduction do bacteria use to reproduce

Answer 28

binary fission

Question 29

what are two advantages to asexual reproduction

Answer 29

can reproduce offspring quickly and doesn't require special cells or a lot of energy

Question 30

a type of reproduction in which one parent organism produces offspring without meiosis and fertilization

Answer 30

asexual reproduction

Question 31

explain why cloning might be beneficial to save endangered animals

Answer 31

It can prevent endangered animals from going extinct and can help increase the population of an endangered species

Question 32

list the qualities of budding

Answer 32

parent produces a bud, bud gets detached and develops into offspring

Question 33

list the qualities of cloning

Answer 33

it's performed in a lab and is used to make copies of organisms or cells with desirable traits

Question 34

what organisms use regeneration

Answer 34

sea urchins, sea stars, and planarians

Question 35

Honeybees and some sharks can sometimes produce offspring with unfertilized eggs what is the name of this type of reproduction

Answer 35

parthenogenesis

Question 36

when organisms produce offspring with unfertilized eggs what type of reproduction is this

Answer 36

parthenogenesis
