cell cycle (f)

Question 1

every cell will have:

Answer 1

cytoplasm, cell membrane, ribosomes, and genetic material

Question 2

what is the cell theory

Answer 2

all living things are made of cells, all existing cells are produced by other living cells, and cells are the basic unit of life

Question 3

is yeast uni or multicellular?

Answer 3

unicellular

Question 4

is kelp uni or multicellular

Answer 4

multicellular

Question 5

are diatoms multi or unicellular

Answer 5

unicellular

Question 6

are bacteria uni or multicellular

Answer 6

unicellular

Question 7

are amoeba uni or multicellular

Answer 7

unicellular

Question 8

what is the importance of the cell cycle?

Answer 8

growth and repair

Question 9

what are the three checkpoints in interphase

Answer 9

g1, s, g2

Question 10

what does g stand for in g1 and g2

Answer 10

growth

Question 11

what does the s stand for in s interphase?

Answer 11

synthesis

Question 12

what are the 5 steps of mitosis

Answer 12

prophase, metaphase, anaphase, telophase, cytokenesis

Question 13

what are the two steps of the cell cycle

Answer 13

interphase and mitosis

Question 14

interphase

Answer 14

cell grows and prepares for division
DNA Replicates
Centrioles appear

Question 15

Prophase

Answer 15

Chromosomes condense (form sister chromatids)
Nuclear membrane disappears
Spindle fibers form

Question 16

metaphase

Answer 16

Spindle fibers connect to the centromere of sister chromatids
Chromosomes move to the middle of the cell

Question 17

anaphase

Answer 17

Sister chromatids separate & begin to move to opposite ends of the cell
They are now individual chromosomes

Question 18

telophase

Answer 18

Nuclear envelope reforms
Chromosomes unwind (become thread like - chromatin)
Spindle fibers break down
Cytokinesis begins

Question 19

cytokenesis

Answer 19

division of the cytoplasm

pinches cells into two equal parts

Question 20

what are the two types of cells

Answer 20

prokaryotic and eukaryotic

Question 21

example of prokaryote

Answer 21

bacteria

Question 22

example of eukaryotic

Answer 22

plants

Question 23

what does prokaryotes use for division

Answer 23

binary division

Question 24

which type of cell has membrane bound organelles and a nucleus

Answer 24

eukaryotic

Question 25

what does eukaryotes use for division

Answer 25

mitosis

Question 26

are eukaryotic multi or unicellular

Answer 26

most are multi but some are unicellular

Question 27

what are the two types of the cell cycle

Answer 27

external and internal

Question 28

external regulation

Answer 28

signals that come from outside of the cell

Question 29

example of external regulation

Answer 29

hormones and nutrients

Question 30

internal

Answer 30

signals that come from the nucleus

Question 31

example of internal regulation

Answer 31

dna in the cell and checkpoints

Question 32

apoptosis

Answer 32

signals are sent to the cell to produce self-destructive enzymes

Question 33

what organells is involved in apoptosis

Answer 33

lysosomes

Question 34

how many chromosomes are there

Answer 34

23 pairs, 46 altogether

Question 35

haploid

Answer 35

Half the number of chromosome from the parent cell

Question 36

how many sets of chromosomes are in a haploid

Answer 36

one

Question 37

meisosis

Answer 37

reproductive cells

Question 38

diploid

Answer 38

the same number of chromosomes as the parent cell

Question 39

how many sets of chromosomes are in a diploid

Answer 39

two

Question 40

mitosis

Answer 40

somatic cellls

Question 41

g1

Answer 41

synthesizes mRNA and proteins in preparation for steps leading to mitosis

Question 42

g2

Answer 42

cell replicates its organelles in preparation of mitosis

Question 43

s in interphase

Answer 43

dna is copied and chromosomes are replicated

Question 44

centromere

Answer 44

holds the chromosome together
