what evolutionary advantage does double fertilization provide
Step by step
Solved in 2 steps
- What is the evolutionary importance of the fruits for the angiosperms?What evolutionary advantages do seed provide over spores? What was early gymnosperm ecology like? What ecological role did gymnosperms perform as the dominant terrestrial plant type 250 million years ago? what were did angiosperms begin to replace gymnosperms as the new dominant plant type in terrestrial ecosystemsWhich of the following is not a characteristic that distinguishesgymnosperms and angiosperms from other plants?(A) dependent gametophytes(B) ovules(C) pollen(D) alternation of generations
- What are the two structures that allow angiosperms to be the dominant form of plant life in most terrestrial ecosystems?The three main parts of a typical mature eudicot seed are the _______ . a. pollen grain, egg, and seed coat b. embryo, endosperm, and seed coat c. megaspores, microspores, and ovule d. embryo, cotyledons, and seed coatWhat do you think is the evolutionary advantage(s) of heterospory over homospory? Do you think it helped the angiosperms to colonize the land?
- In a typical angiosperm, what is the sequence of structures encountered by the tip of a growing pollen tube on its way to the egg? ovary → style → stigma stigma → style → ovary ovary→ stigma→ style stigma→ ovary → styleHow did the evolution of the flower promote the explosive diversification of the angiosperms in the cretaceous?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.
- 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 МacВook Pro G Search or type URL @ 2# $ & * 2 3 4 6 8 W E R YWhich of the following statements best compares the two dominant lineages of modern angiosperms? -Monocots are monophyletic whereas eudicots have multiple origins. -Monocots have only one pistil per flower whereas eudicots have three. -Monocots have only one cotyledon whereas eudicots have two. -Monocots are lycophylls whereas eudicots are euphylls. -Monocots have only one stamen per flower whereas eudicots have six.Are gymnosperms heterosporous or homosporous? Explain what this means. What are the evolutionary "advances" represented by the seed?
