reproduction

Question 1

smallest structure in an organism

Answer 1

cell

Question 2

where are germ cells found

Answer 2

reproductive organs

Question 3

what structure becomes tightly packed during cell division?

Answer 3

chromosones

Question 4

what is a chromosone made up of

Answer 4

dna

Question 5

interphase

Answer 5

chromosones replicate themselfs

Question 6

telophase

Answer 6

2 daughter cells form

Question 7

anaphase

Answer 7

cell elongates and chromosones move toward poles

Question 8

metaphase

Answer 8

chromosones line in the middle

Question 9

procces where chromosones line up and exchange genetics in the middle

Answer 9

crossing over

Question 10

when meiosis 2 begins how many daughter cells are there

Answer 10

2

Question 11

what things happpend in mitosis

Answer 11

body cells divide- one stage of divisiion-creates 2 diploid cells-identical to parent cell-no genetic diversity

Question 12

what do meiosis and mitosis have in commen

Answer 12

a type of cell division- replicates DNA- creates new cells

Question 13

what things happen is meiosis?

Answer 13

sex cells divide-2 stages-4 haploid cells-different then parent cell- creates genetic diversity

Question 14

what is a cell?

Answer 14

some contains nucleus but all contain genetic material for reproduction

Question 15

what is DNA?

Answer 15

deoxyribonucleic acid- hereditary material found in almost all living things

Question 16

chromosones

Answer 16

made up of 23 pairs of chromosones- contain DNA

Question 17

nucleus

Answer 17

controls functions of the cell and reproduction- inside there is chromosomes which hold DNA

Question 18

Binary fission

Answer 18

fully grown parent cell splits into 2 halves

Question 19

fragmentation

Answer 19

body of parent breaks into a peice and creates a new organism

Question 20

budding

Answer 20

offspring grows out of body of an organism

Question 21

vegitative reproduction

Answer 21

new organisms arise with spore of seed

Question 22

gamete

Answer 22

sex cells formed by meiosis

Question 23

zygote

Answer 23

as a sperm enters during fertilazation, the two fuse to for zygote. with 23 chromosomes and 46 total

Question 24

mutation

Answer 24

change in the DNA system and causes changes in an organism - appearance how its grows etc

Question 25

sickle cell anemia

Answer 25

disorder that breaks down red blood cells

Question 26

wingless fruit fly

Answer 26

genes responsible for wing formation to be mutated.
