the part of the embryo which develops into the roots is the
radical

40
geranium plant cells are generally diploid or monoploid
diploid
41
pollen tubes are passageways for
sperm nuclei
42
self-pollination can be avoided by
removing the anthers

| becomes upper part of plant
50
how do babies get bigger
mitosis
51
what re the fuzzies on a root
root hairs
52
what is the purpose of root hairs
increase surface areas for water osmosis
53
pollinators
move sperm from A to B
54
fertilization in humas

55
meiotic division happens in the
testes/ovary
56
made of maternal and embryonic tissue

ovulation
corpus luteum
menstruation
60
which two structures mainly produce the hormones that control reproduction

61
multiple births may occur with
multiple ovulations
62
which stage of the menstrual ccle does not take place if zygote formation occurs
menstruation
63
how does human embryo recieve most of its nourishment

64
follicle is a cavity where
a. an egg cell is produced
b. an egg cell is fertilized
c. zygote undergoes cleavage
an egg cell is produced
65
when does ovulation occur
in the middle of the cycle: day 14
66
what hormone triggers ovulation
LH leutenizing hormone
67
where does the LH hormone come from

69
where does FSH come from
pituitary
70
where does FSH target
ovary
71
FSH does what
makes follicle get egg of the month and puts it in follicle bubble
72
in the first half of the menstrual cycle

| less progestrone
73
later half of menstrual
more progestrone
| less estrogen

hypothalamus
pituitary
ovary
uterus
75
the 3 cell cup shape thing

81
endoderm makes
