Ch 10 Mitosis

Question 0

Cell size is Limited by diffusion

Answer 0

CO2 and O2

Question 1

Cell size

Answer 1

Variety of sizes, 8um 0.000001 (red blood cells) to 1m (nerve)

Question 2

Cell size is Limited by DNA

Answer 2

Most cells with one nucleus, could not produce amount of enzymes required

Question 3

Cell size is Limited by surface area to volume ratio

Answer 3

3:1

Question 4

Role of chromosomes

Answer 4

Visible only right before and right after cell division, it contains DNA

Question 5

Chromosomes

Answer 5

Exist as chromatin during most of life cycle

Question 6

Cell cycle

Answer 6

Interphase and mitosis

Question 7

Interphase

Answer 7

cell growth, DNA replication, preparation for mitosis

Question 8

Phases of mitosis

Answer 8

Prophase, metaphase, anaphase, telophase

Question 9

In Prophase

Answer 9

Chromatids join at the centromere, nuclear membrane disappears, nucleolus disintegrates, centrioles go to the opposite ends of the cell

Question 10

In metaphase

Answer 10

Chromatids attach to spindle fibers at the centromere, chromatids line up on the equator

Question 11

Anaphase

Answer 11

Move away from each other

Question 12

In anaphase

Answer 12

Chromatids pull apart, chromatids are called chromosomes, chromosomes move to the opposite ends

Question 13

Telophase

Answer 13

Final phase

Question 14

In telophase

Answer 14

Chromosomes unwind, spindle fibers break down, nucleolus reappears, nuclear membrane reforms

Question 15

Cytokinesis

Answer 15

Division of cytoplasm- furrow

Question 16

Cytokinesis happens during

Answer 16

Telophase

Question 17

In cytokinesis

Answer 17

Cell membrane pinches together (called furrow) in 2 daughter cells-animals, plants-cell plate formed

Question 18

In cell cycle

Answer 18

Cell doubles in size, organelles double in number
