a new organism that grows from a bud
26
what is spore formation
produces algae, bacteria, fungi
27
what is fragmentation
breaks into a new individual
28
what is vegetative propagation
new plant grows from a runner of a plant
29
what are the 3 things that are considered mutagens
1. deletion 2. addition 3.substitution
30
what's a positive mutagen
a benefit for survival
31
what's a negative mutagen
a harm for survival
32
what's a neutral mutagen
has no affect for survival
33
what is a allele
a different version of a gene
34
what's chromatin
dan that is coiled
35
where are genes located
in chromosomes
36
organelles
a part of a cell with a specific function
37
mitochondria
the powerhouse of a cell
38
lysosomes
breaks down stuff
39
ribosomes
makes protein
40
vacuole
stores food and water
41
cell wall
supports the structure of the cell
42
cell membrane
controls what goes in and what goes out
43
cytoplasm
carries out functions for cells survival
44
rough ER
packages protiens
45
smooth ER
makes fats
46
vesicle
transports protien to the Golgi body to export out
47
Golgi body
packages proteins to transport to other cells
48
chloroplast
traps energy from the sun to make glucose
49
centriole
used in cell division
50
nucleus
controls the activities of the cells and contains dan
51
what are the 3 main phases of cell cycle
interphase, mitosis, cytokines
52
prophase
chromatin coils up and the cell membrane starts to disappear as spindle fibres start to grow
53
meta phase
nuclear membrane disappears, spindle fibres grow and chromosomes move out to the cytoplasm
54
anaphase
spindle fibers pull chromosomes apart and move them towards the opposite end of cell
55
telophase
chromosomes uncoil and disappear, new nuclear membrane appears around the new set of chromosomes
56
positive terminal
location that accepts e-
57
negative terminal
location that readily gives up e-

electrolytes and senator
59
what is kinetic energy
movement
60
what is potential energy
stored energy
61
what does a conductor do

62
what does an insulator do
doesn't let energy flow easily
63
what is physical change
change that doesn't change in the chemical composition of matter
64
what is chemical change
change that does have a change in the chemicals composition of matter
65

66
what are molecules
chemically bonded together which can be made up the same atoms or different atoms
67
what are pure elements

G1 S phase G2 M phase
79
what is the cell division of animal cells
a contractile ring of cytoskeletal fibers pinches the cell in two
80
what is the cell division of plant cells
a new structure called the cell plate is built down the middle of the cell to partition it in two
81
what is the cell cycle checkpoints
detect and repair DNA damage
82
