-Vegetative reproduction in a creeping stem differs from the growth of an ordinary stem because after a creeper is rooted, it

separates from the parent plant and grows independently

grows faster

dies off

produces seeds

-A gardener grows a new plant from cutting by means of





-An animal produced by parthenogenesis developms from

A fertilized egg

An unfertilized egg

A regenerated part

Diploid spore

-In flowering plants, a megaspore within the _________ becomes the

Stamen, microspore

Anther, male gametophyte

Ovule, female gametophyte

Pistil, sporophyte

-Male gametophytes are commonly called _________ and contain __________

Megaspores, no

Spores, eight

Pollen cells, three

Microspores, eight

-In flowering plants, a microspore within the _____ becomes the future

anther, male sporophyte

anther, male gametophyte

ovule, female gametophyte

ovule, female sporophyte

-A diploid cell in the ovule divides by ________ to form four ________

Meiosis, haploid

Mitosis, diploid

Mitosis, haploid

Meiosis, diploid

-In flowering plants, roots, stems and leaf tissue form the ________
generation, which mans all cells contain _____ of each type of

Gametophyte, two

Gametophyte, one

Sporophyte, two

Sporophyte, one

-As vascular plants evolved, the __________ generation became smaller,
lived, and lacked ___________ tissue.

Gametophyte, vascular

-Megaspores and microspores are formed during a plant's life cycle. How
might they have gotten their different names when both are actually

Microspores are actually diploid but appear to be haploid

Megaspores are larger in size than microspores

Megaspores are more numerous than microspores

Microspores are the direct result of mitosis, while megaspores are the
direct result of meiosis.

-A walk through the forest finds many moss plants growing near a brook.
Which of the following statements would most likely be correct?

You are observing a diploid generation

You are observing a haploid generation

You are observing both sporophyte and gametophyte plants

You are observing both diploid and haploid plants

-A weekly visit to the same site where moss plants grow results in the
discovery of some small stalk-like parts growing from the moss. Most
these parts are

a disease of the moss plants

evidence of the gametophyte generation

evidence of the sporophyte generation

the flowering structure of the moss plant

-Petals of a plant are associated with the flower and sexual
Therefore, their chromosome number most likely would be

diploid for all flowering plants

haploid for all flowering plants

diploid early in the growing season but haploid later on

diploid for some species and haploid for other species

statements be true or false? Explain.

False. A bulb contains stored for for the plant only.

True. A buld's nutrients are similar to foods used by humans

False. Tulip bulbs are most likely poisonous.

False. A bulb's nutrients are different that those needed by humans.
