Gracie - Cell Reproduction

Question 1

Mitosis

Answer 1

second stage of cell cycle - chromosomes condense and separate, divided into four phases/steps

Question 2

Fragmentation

Answer 2

some organisms, when cut at certain points, will either regenerate body parts or split into two new organisms.

Question 3

Chromosomes

Answer 3

the DNA of a cell is organized into visible structures.

Question 4

Metaphase

Answer 4

the phase of mitosis where the chromosomes are lined up in the middle

Question 5

Binary Fission

Answer 5

cell division of bacteria or prokaryotic cells.

Question 6

Chromatids

Answer 6

each half of a duplicated chromosome, held together at the cetromere.

Question 7

Interphase

Answer 7

the stage where the cell copies its organelles and DNA, cells spend most of their lives in this stage

Question 8

Prophase

Answer 8

the phase of mitosis where the nucleus disappears and the chromosomes are visible

Question 9

Budding

Answer 9

a new organism grows off an existing organism

Question 10

Eukaryotes

Answer 10

complex cells that have a nucleus and a complicated cell cycle

Question 11

Homologous

Answer 11

chromosomes with matching information, you get one from mom and one from dad in each pair

Question 12

Anaphase

Answer 12

the phase of mitosis where the chromosomes separate to opposite sides of the cell

Question 13

Gametes

Answer 13

sex cells (eggs or sperm)

Question 14

Cell cycle

Answer 14

begins when the cell is formed and ends when the cell divides and forms new cells.

Question 15

Cytokinesis

Answer 15

the last stage of the cell cycle where the cytoplasm divides

Question 16

Meiosis

Answer 16

the cell cycle for making sex cells, creates four non-identical sex cells - separated into 8 phases/steps

Question 17

Prokaryotes

Answer 17

less complex cells that go through binary fission

Question 18

Sexual

Answer 18

reproduction requires two parents, the offspring is not genetically identical to the parent

Question 19

Telophase

Answer 19

the phase of mitosis where the nuclear membrane reappears around the two sets of chromosomes

Question 20

Asexual

Answer 20

reproduction that involves one parent, offspring are genetically identical to the parent

Question 21

How many chromosomes does a human have?

Answer 21

46

Question 22

How many chromosomes does a lion have?

Answer 22

32
