Which statement below is correct regarding the formation of the endosperm in angiosperms? O the endosperm is formed from the female gametophyte and is haploid O a single sperm nucleus fertilizes the egg nucleus to become the diploid zygote O a sperm nucleus forms both the zygote and the endosperm through double fertilization O a second sperm nucleus fuses with the two polar nuclei of the egg sac

Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. It is most likely: a gymnosperm a monocot a eudicot a basal angiosperm
In the mature angiosperm seed, the nutritive tissue is triploid. This tissue is formed from; Two polar nucleii fusing with a sperm cell The synergids fusing with a sperm cell The sperm fusing with the egg cell The embryo
Which of the following is correct regarding female gametophyte development in Angiosperms? The female gametophyte develops in the anther The female gametophyte develops in an ovule within an ovary A female gametophyte develops from all four megaspores produced via meiosis All cells of the female gametophyte are haploid
The best answer describing angiosperm fertilization is: O a single sperm fertilizes an egg a single sperm fertilizes the antipodal cells O a single sperm fuses with the two polar nuclei one sperm fertilizes the egg, one fuses with the two polar nuclei to create 3N tissue one sperm fertilizes the egg, one fuses with the antipodal cells to create 3N tissue
Most of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.
Gymnosperms are heterosporous plants. This means that; They reproduce by using one type of spore Their spores are covered with sporopollenin They produce separate male and female spores
When two gametes come together from different plants, the zygote matures into a: Sporophyte O Gymnosperm O Bryophyte O Antheridium
Which of the following is true for bryophyte reproduction but NOT angiosperms or gymnosperms? Male and female plants must be close to one another for fertilization to occur. There are separate male and female gametes. O Plants are bisexual. They experience alternation of generations.
Why are gymnosperms nicknamed "naked seeds?" Because they originate from an egg cell only, rather than an egg cell and a sperm cell. Because they are not encased by the mature ovary. Because they originate from a sperm cell only, rather than an egg cell and a sperm cell. Because they are encased by a protective sheath.
