Q

What are most flowers?

A

most flowers are monoecious

32
Q

Can some flowers be dioecious?

A

yes

33
Q

What does monoecious mean?

A

One flower can have two genders

34
Q

What does dioecious mean?

A

Each flower has one gender.

35
Q

What does the microspore mother cell do?

A

The microspore mother cell does asexual reproduction in the ovary

36
Q

What is the microphyte?

A

The doorway to the ovuale

37
Q

What is pollination?

A

The transfer from the pollen from the stamen to the stigma

38
Q

What is self pollination?

A

where the pollen from the stamen attaches to the stigma of the same flower

39
Q

What are the two ways that pollen travel?

A

Thru wind and animals

40
Q

What is the problem with pollen traveling by wind?

A

It is trial and error because there is more pollen than flowers. ex: wheat, barley

41
Q

What animals pollinate?

A

Bees

42
Q

What is the end result of pollination?

A

pollen on the stigma

43
Q

What happens when the pollen sticks to the stigma?

A

The flower is ready to start sexual reproduction

44
Q

What is the function of the tube nucleus?

A

The tube nucleus controls the growth of the tube

45
Q

What does the tube nucleus release?

A

two sperm cells

46
Q

What polar nucleus?

A

Two haploid nuclei in the centre of the embryo sac of flowering plants.

47
Q

How many sperms does double fertilization?

A

two sperms

48
Q

What is double fertilization?

A

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
Q

What are the two types of flowers?

A

monocots and dicots

50
Q

What do monocot flowers have?
