Angiosperms and gymnosperms are most alike because they share the traits of a vascular system, the ability to grow tall, the ability to live in dry or wet environments and the ability to produce seeds.
What is the evolutionary advantage that angiosperms have over gymnosperms?
Introduction to Angiosperms Flowering plants are able to survive in a greater variety of habitats than gymnosperms. Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized.
What adaptation arose in gymnosperms and angiosperms that allowed reproduction on dry land and over great distances?
In sexual reproduction, an alga simply releases gametes into the water, and the current carries the sex cells to another individual. What adaptation arose in gymnosperms and angiosperms that allowed reproduction on dry land and over great distances? grow tall and form branches.
What adaptations give flowering plants a reproductive advantage over gymnosperms?
Flowering plants have a reproductive advantage over gymnosperms because of different adaptations such as having flowers t allow for pollination and fruit for seed dispersal. Pollination can b allowed by wind, or by pollen being carried by animals.
Which specific adaptation S did angiosperms evolve that distinguishes angiosperms from other seed plants Select all that apply?
Angiosperms have developed flowers and fruit as ways to attract pollinators and protect their seeds, respectively. Flowers have a wide array of colors, shapes, and smells, all of which are for the purpose of attracting pollinators.
In what way was the seed such an important adaptation in the evolution of plants?
Key Points The evolution of seeds allowed plants to decrease their dependency upon water for reproduction. Seeds contain an embryo that can remain dormant until conditions are favorable when it grows into a diploid sporophyte.
How did angiosperms adapt to land?
Angiosperms, the flowering plants, utilize flowers to attract pollinators, and some encase their seeds in fruits to aid in their dispersal. Early land plants evolved such structures and, as a result, expanded their habitable environment in a vertical direction.
What is an adaptation that angiosperms have that gymnosperms do not?
Though they both have sporophyte-dominated life cycles, angiosperms and gymnosperms differ in that angiosperms have flowers, fruit-covered seeds, and double fertilization, while gymnosperms do not have flowers, have “naked” seeds, and do not have double fertilization.
What reproductive adaptation did plants evolve on dry land?
Seeds and Pollen as an Evolutionary Adaptation to Dry Land Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes ), seeds contain a diploid embryo that will germinate into a sporophyte.
Why are flowers an important adaptation of flowering plants?
Flowers are an adaptation that helps many plants make seeds to grow new plants. Some flowering plants use bright petals and sugar water called nectar to get insects to visit. Visiting insects help move pollen among flowers so seeds will form.
Why are flowers an advantageous adaptation?
Those specialized flowers are able to attract organisms to help pollinate and distribute seeds. Another cool advantage is the fruit/seed packaging. When they do, they are able to spread the seeds across wide areas after the animal poops out the seeds.
When did angiosperms become the most abundant plant group?
Angiosperms surpassed gymnosperms by the middle of the Cretaceous (c. 100 MYA) in the late Mesozoic era, and today are the most abundant and biologically diverse plant group in most terrestrial biomes.

When did the gymnosperms reach their greatest diversity?
Gymnosperms expanded in the Mesozoic era (about 240 million years ago), supplanting ferns in the landscape, and reaching their greatest diversity during this time. The Jurassic period was as much the age of the cycads (palm-tree-like gymnosperms) as the age of the dinosaurs.
Describe the significance of angiosperms bearing both flowers and fruit The first plants to colonize land were most likely related to the ancestors of modern day mosses (bryophytes), which are thought to have appeared about 500 million years ago.
Why are progymnosperms a transitional group of plants?
Progymnosperms were a transitional group of plants that superficially resembled conifers (cone bearers) because they produced wood from the secondary growth of the vascular tissues; however, they still reproduced like ferns, releasing spores into the environment. At least some species were heterosporous.
