Exam 37: Reproduction in Flowering Plants

Potatoes reproduce asexually using modified stems called _______.

Vernalization refers to the

Recall what you have read about the genes involved in flowering in angiosperms: APETALA1 (AP1), CONSTANS (CO), FLOWERING LOCUS D (FD), FLOWERING LOCUS C (FLC), and FLOWERING LOCUS T (FT).Create a genetic pathway for flowering using the genes listed above.(Use "" to indicate the product of a gene that increases the expression of another gene, use "" to indicate the product of a gene that decreases the expression of another gene, and use "+" to indicate the product of a gene that binds to the product of another gene.)

A plant in which four haploid female nuclei fused with one sperm to produce endosperm would most likely have four

You are asked to identify the version of florigen found in carnivorous sundew plants.You decide to start by using biochemical methods to isolate the florigen molecule, which is a(n)

The chemical signal that induces flowering is called

Rapid loss of populations due to genetic uniformity has been documented in which species?

In biochemically determined self-incompatibility, where does pollen tube growth generally stop?

If an insect chews through a flower, from outside to center, in what order will it eat the flower parts?

In stable environments, which type of reproduction is most likely to become increasingly common?

Refer to the figure showing the initial stage of double fertilization. If the pollen grain shown is self pollen, what does the developmental progress of the grain, as indicated in the figure, tell us about this plant's ability to self-pollinate?

It takes a great deal of effort to detassel corn (remove male flowers).Why can't corn plants simply be sprayed with a meiosis inhibitor to halt pollen production?

Stamens and carpels produce the male and female

Refer to the figure showing the initial stage of double fertilization. Identify the cell from the microgametophyte that will form the sperm.

Short-day plants bloom

After pollination, which of the following events is crucial for fertilization?

APETALA1 is a _______ identity gene whose expression causes _______ meristem cells to become reproductive, regardless of environmental cues.

A mutant plant with the inability to form pollen tubes has no genetic defects in the pollen grains or cells.Examination of the carpel would show that the megagametophyte is lacking functional _______.

In a short-day plant like cocklebur with a critical day length of 15 hours, flowering can be induced by _______ hours of light alternating with _______.

Which statement about vegetative reproduction is most likely to be true?
