28
cells without a true nucleus
prokaryoyic
29
cells with true nucleus
eukaryotic
30
- a living diuble layer of proteins and carbohydrates - separates the cell membrane from its external environment
cell membrane
31
a double membrane of fats and proteins
nuclear
32
a double membrane of fats and proteins
nuclear
33
the colloidal solution enclosed by the nuclear membrane
nucleoplasm
34
structures for protein synthesis
nucleolus
35
structures for protein synthesis
nucleolus
36
organize structures of DNA and protein found within cells
chromosomes
37
- sex cell division - process that produces 4 daughter cell with haploid number of chromosomes as the parent cell
meiosis
38
- also known as reduction division - reduction for chromosomes numbers
meiosis 1
39
- occupies the longest duration of meiosis
prophase 1
40
- occupies the longest duration of meiosis
prophase 1
41
replicated chromosomes appear as long slender thread
leptonema
42
replicated chromosomes appear as long slender thread
leptonema
43
synapsis occurs
zygonema
44
pairing of homologous chromosomes
synapsis
45
pair of homologous chromosomes
tetrad
46
-chromosomes continue to become shorter and thicker - crossing over takes place
pachynema
47
a series of exchange of genetic material between the specific regions of the homologous chromosomes
crossing over
48
tetrads tend to repel each other
diplonema
49
the area of contact between two chromatids
chiasma
50
the area of contact between two chromatids
chiasma
51
coiling and contraction of the chromosomes continue
diakinesis
52
synapsed homologous chromosomes are aligned at the equator of the cell
metaphase 1
53
the spindle fibers move the tetrads apart pulling the chromosome toward the oppposite sides of the cell
anaphase I
54
the spindle fibers move the tetrads apart pulling the chromosome toward the oppposite sides of the cell
anaphase I
55
double stranded chromosome
dyads
56
di
57
double stranded chromosomes
dyads
58
double stranded chromosomes
dyads
59
the dyads reach the poles of the cell
telophase I
60
a period of growth
interkinesis
61
deals with the seperation of two chromotids in a chromosomes
Meiosis II
62
the centrioles radiate spindle fibers as they move to the opposite sides of the cell
Prophase II
63
The centromeres of each dyad are directed to the equator of the cell
metaphase II
64
The centromeres divide and the chromatids or single stranded chromosome (monads) are pulled by spindle fibers toward the opposite poles
Anaphase II
65
production of two daughter cells with the same quantity and quality of chromosomes as the parent cell
mitosis
66
- centrioles are moving apart - chromosomes appear as long thin threads - nucleolus is becoming less distint -nuclear membane is still visible - asters are formed
Early prophase
67
- pair of centrioles begins to organize spindle fibers - sisters chromatids are formed with a centromere as their point of attachment
Middle Prophase
68
- pair of centrioles begins to organize spindle fibers - sisters chromatids are formed with a centromere as their point of attachment
Middle Prophase
69
Contains two sets of chromosomes
diploid cell
70
Contains two sets of chromosomes
