Double fertilization in angiosperms results in a __________ zygote and a triploid __________.
Double fertilization in angiosperms results in a __________ zygote and a triploid __________.
Double fertilization is the process by which two sperm cells are introduced to the ovule. One sperm (
) fertilizes the egg (
), creating a zygote(
). The other sperm combines with the two polar nuclei (
), forming the endosperm (
) that will nourish the embryo.

Which of the following is true of the sporophyte of a plant?
Which of the following is true of the sporophyte of a plant?
The sporophyte produces spores, which grow into gametophytes. The gametophyte produces both ovules and pollen, which unite to form a zygote. The zygote grows into the next sporophyte. The plant life cycle continues to alternate between these stages. In flowering plants, the gametophyte stage has been greatly reduced compared to the sporophyte stage.

Pollination is a process in which pollen is transferred between which of the following two structures of an angiosperm?
Pollination is a process in which pollen is transferred between which of the following two structures of an angiosperm?
Pollination is the process in angiosperms through which pollen is transferred from the male anther to the female stigma. Pollination can be either abiotic (i.e. by the wind) or biotic (i.e. by an animal). This process precedes fertilization.

Which of the following can be best described as a method of pollination?
Which of the following can be best described as a method of pollination?
Pollination is defined as the transfer of pollen from the male anther to the female stigma of an angiosperm. There are abiotic and biotic methods of pollinations. Abiotic pollination includes wind and water while in biotic pollination another organism facilitates pollination.

Diecious plants (such as Gingko biloba) have separate sexes rather than having both male and female parts on a single plant.
Given that ginkgo is diecious, which plants would you expect to produce pollen?
Diecious plants (such as Gingko biloba) have separate sexes rather than having both male and female parts on a single plant.
Given that ginkgo is diecious, which plants would you expect to produce pollen?
Pollen is the male part of the plant, and thus is only produced by male ginkgo plants. Females have ovules with a fleshy, fruit-like outer layer and rely on the males plants for pollination. (Ginkgo is a gymnosperm and thus technically not a flowering/fruit-producing plant.)
