25
What filament?
gets sacks up higher in the air
26
What is the job stamen?
The job of the state is made pollen.
27
What is the stigma?
produces sticky liquid to trap the pollen
28
What is the style?
gets the stigma higher in the air
29
What is the ovary?
The key to sexual reproduction
30
What is the ovule?
the ovary could have multiple of ovary
31
What are most flowers?
most flowers are monoecious
32
Can some flowers be dioecious?
yes
33
What does monoecious mean?
One flower can have two genders
34
What does dioecious mean?
Each flower has one gender.
35
What does the microspore mother cell do?
The microspore mother cell does asexual reproduction in the ovary
36
What is the microphyte?
The doorway to the ovuale
37
What is pollination?
The transfer from the pollen from the stamen to the stigma
38
What is self pollination?
where the pollen from the stamen attaches to the stigma of the same flower
39
What are the two ways that pollen travel?
Thru wind and animals
40
What is the problem with pollen traveling by wind?
It is trial and error because there is more pollen than flowers. ex: wheat, barley
41
What animals pollinate?
Bees
42
What is the end result of pollination?
pollen on the stigma
43
What happens when the pollen sticks to the stigma?
The flower is ready to start sexual reproduction
44
What is the function of the tube nucleus?
The tube nucleus controls the growth of the tube
45
What does the tube nucleus release?
two sperm cells
46
What polar nucleus?
Two haploid nuclei in the centre of the embryo sac of flowering plants.
47
How many sperms does double fertilization?
two sperms
48
What is double fertilization?
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm).
49
What are the two types of flowers?
monocots and dicots
50
What do monocot flowers have?
It has three petals or multiples of three petals.
51
What do dicot flowers have?
it has four or five petals or multiple of four or five.
52
What is an example monocot?
tulip or lily
53
What is an example of a dicot?
Rose
54
How many parts are there in the seed?
there are three parts to the seed
55
What are the three parts to the seed?
The seed coat, embryo, endosperm
56
What is fruit?
mature pistil containing seeds and other florals parts
57
What are the types of fruits?
fleshy, dry,
58
What are the characteristics of fleshy fruit?
moist and juicy
59
What is the pome?
0 percent its pistil is edible
60
What is a drupe?
fifty percent of the pistil is edible
61
What is berry?
100 percent of the berry is edible.
62
What is an example of a drupe?
peach
63
What is an example of a pome?
apple
64
What is example of a berry?
tomato
65
What are dehiscent fruits?
plants that have seams ex: peas
66
What are indehiscent fruits?
seeds ex: dandelions
67
What are the three ways foods disperse?
mechanical mechanism, animals, water, wind
68
What happens during mechanical mechanism?
It opens quickly and violently through the air, and literally shoots the seeds thru the air
69
How do animals disperse seeds?
they poop the seeds out or it gets stuck in their hair,
