Donatelle 249 solutions The Brazil nut tree, Bertholletia excels, is native to tropical rain forests of South America. The agouti (Dasyprocta spp.), a cat-sized rodent, is the only animal with teeth strong enough to crack the hard wall of Brazil nut fruits. It typically eats some of the seeds, buries others, and leaves still others inside the fruit into which moisture can then enter and allow the remaining seeds to germinate. The agouti is
most directly involved in dispersal of which of the following structures? Scarlet gilia (Ipomopsis aggregata) usually has red flowers. In certain populations in the Arizona mountains, however, the flowers range from red to pink to white. In early summer, most (but not all) of the flowers were red. Six to eight weeks later, the same individual plants were still present; the flowers ranged from pink to white, and few red flowers were present. The major
pollinators early in the season were two species of hummingbirds active during the day; they emigrated to lower elevations, and the major pollinator later in the season was a hawk moth (a type of moth). The hawk moth was most active at sunset and later, and it preferred light pink to white flowers after dark. When hummingbirds were present, more red flowers than white flowers produced fruit. When only hawk moths were present, more white flowers produced fruit. Students also viewedAnswer Verified
Hint: Both have similar basic parts and structure of the plants, thus making it similar in structure except the flowers because the gymnosperm is found to be more simple as compared to the angiosperm that is more advanced like they produce fruit to protect seed.Complete answer:
Note: The term angiosperm was coined by Paul Herman in 1690. The early characteristics of seed plants were evident in the fossil of the late Devonian period around 383 million years ago. The ancestors of flowering plants diverged from the gymnosperms in the Triassic period (245-202 million years ago). They diversified early during the early cretaceous period. Which of the following describes a difference between angiosperms and gymnosperms?Angiosperms, are also known as flowering plants and having seeds enclosed within their fruit. Whereas gymnosperms have no flowers or fruits and have naked seeds on the surface of their leaves.
What is the difference between gymnosperms and angiosperms quizlet?Gymnosperms have naked seeds, don't have flowers or fruits, and have a haploid endosperm in the seeds (endosperm is produced before fertilization), while Angiosperms have enclosed seeds, flowers, fruits, and have a triploid endosperm in the seed (endosperm produced during triple fusion).
What is the main difference between gymnosperm and angiosperm reproduction?In angiosperms, the female gametophyte exists in an enclosed structure—the ovule—which is within the ovary; in gymnosperms, the female gametophyte is present on exposed bracts of the female cone. Double fertilization is a key event in the lifecycle of angiosperms, but is completely absent in gymnosperms.
Which of the following statements best distinguishes gymnosperms from angiosperms?Which of the following statements best distinguishes gymnosperms from angiosperms? Angiosperms have their ovules and seeds enclosed in a structure.
