gives the offspring half of the maternal traits and half of the paternal traits
thus creating a unique organism.

A

Sexual Reproduction

34
Q

Sexual reproduction in ________ is also common.

Q

The big trees that you see in your surroundings are all ________, the most
dominant generation in the life cycles of angiosperms.

A

sporophytes

53
Q

Pollination is the transfer of pollen from the _______ to the ______ of a flower.

A

ANTHER to the STIGMA

54
Q

happens when the pollen lands on the stigma of
the flower coming from the same plant.

A

Self Pollination

55
Q

occurs when the pollen lands on the stigma of a flower, the
pollen tube cell grows toward the location of the embryo sac, forming a pollen tube.

A

Cross Pollination

56
Q

As the pollen tube grows, the
generative cell divides to form ______________

A

two sperm cells or nuclei

57
Q

Inside the embryo sac, one sperm nucleus fuses with the two
polar at the middle of the embryo sac forming a _________.

A

triploid (3N) endosperm nucleus

58
Q

The fusion of the sperm and egg
nuclei gives rise to the ________, which will become a new plant.

A

zygote

59
Q

Since two fertilization events took place, the process is
called _________

A

double fertilization

60
Q

At this point, the zygote divides numerous times and a protective tissue envelops the
_________, resulting in the formation of a seed.

A

Embryo

61
Q

_________ triggers hormonal changes that cause the ovary to begin it transformation into a fruit

A

Fertilization

62
Q

What happens when the flower does not pollinate?

A

the fruit usually does not develop, and the entire flower wither and falls away.
