Question

Double fertilization in an angiosperm produces a diploid zygote and a haploid polar nucleus. a diploid zygote and a diploid endosperm. a diploid embryo and a triploid zygote. a triploid embryo and a diploid endosperm. a diploid zygote and a triploid endosperm. Which of the following is the correct order of floral organs from the outside to the complete flower? petals-sepals-stamens-carpels sepals-stamens-petals-carpels spores-gametes-zygote-embryo sepals-petals-stamens-carpels male gametophyte-female gametophyte-sepals-petals Why is sexual reproduction important? It allows animals to conserve resources and reproduce only during optimum The resulting diverse phenotypes may enhance survival of a population in environment. It can result in numerous offspring in a short amount of time. It enables isolated animals to colonize a habitat rapidly. Both A and D are important. Which of the following statements is NOT true about fertilization? Amphibians, birds, and reptiles lay shelled eggs. Most terrestrial animals practice internal fertilization. Many terrestrial males have a copulatory organ for sperm transition? Internal fertilization is required for the production of shelled Most aquatic animals practice external fertilization, releasing Protists are alike in that all are multicellular. photosynthetic.
