Seeds have a protective coat and storage tissue to support growth. Several layers of hardened tissue prevent desiccation, freeing reproduction from the need for a constant supply of water. Seeds can be stored for up to a year in a cool, dry place. They can also be kept in an airtight container in the refrigerator for longer periods of time.

Why are seeds an evolutionary advantage for seed plants Edgenuity?
There is an evolutionary advantage to seed plants. Seeds protect and nourish young, healthy plants. They also provide food for insects, birds, and other animals that eat the seeds. Seed plants have been around for millions of years. In fact, they are the oldest living things on the planet.
The oldest known seeds date back to the Cambrian Period, about 540 million years ago, when the first life forms appeared on Earth. Since then, the number of seeds in the world has increased by more than a factor of 10,000, according to a study published last year in Proceedings of the National Academy of Sciences.
What are two advantages of seed plants?
The seeds protect the embryo from harsh environmental conditions. They provide sustenance to the embryo. The chances of successful reproduction are increased by the dispersal of the seeds to far-off places. In the wild, seeds are dispersed by birds, insects, and other animals. Seeds can also be carried by the wind or carried on the ground by animals such as deer, elk, moose, or caribou.
In the United States, the most common way of dispersing seeds is by seed-carrying birds. These birds can be found all over the country, but they are most commonly found in the Great Plains and the Rocky Mountains. Some of these birds carry seeds in their beaks, while others carry them on their feet. Birds of prey are also important dispersers of seeds, especially during the breeding season.
What are the evolutionary advantages of seeds over spores?
The seed coat offers protection and nourishment that aren’t available for spores. spores need to undergo a reproduction process before they’re able to grow, while seed coats contain a fully developed embryo that is ready to grow.
Seed coats are also more resistant to heat and cold than spores, which are more susceptible to drying out. Seed coats also have a longer shelf life, meaning that they can be stored for longer periods of time and still be viable.
What are 3 advantages to seeds?
I) They provide nourishment and parental care to the developing embryo, ii) They protect the embryo from harsh environmental conditions. iii) They generate new genetic combinations leading to variations.
Explain the advantages the seeds offer. (a) The seeds are edible, i.e., they can be eaten raw or cooked. (b) Seeds are easy to transport and store, and they are not subject to pests or diseases. iv) Seed germination is rapid and the seedlings grow quickly. v) There is no need for fertilizers or pesticides. vi) It is possible to grow a large number of seeds in a small area. b.
The seed is sterile, meaning that it does not contain any genetic material from the parent plant. c. Seeds do not have the ability to germinate in the presence of light. d. Seedlings are susceptible to diseases and pests. e. They are difficult to propagate. f. There are no natural predators. g. A seedling is not capable of self-fertilization. h.
It takes a long time for a seed to reach maturity, which can take up to a year or more, depending on the type of seed, the climate and other factors.
Why are seed plants considered the most successful land plants?
Better transportation for water, nutrients and reproduction is what makes a plant successful. The structures allow the plants to colonize farther away from the source of water. A perennial is a plant that grows year after year. It does not produce new leaves, flowers or fruit. A vascular is an annual plant. The plant produces new leaf, flower and fruit in the spring and summer.
How did seed plants evolve?
Over time, some progymnosperms evolved into seed ferns. Female sex cells stayed with the parent plant, and waited for male sex cells to arrive. Seed plants are the most common type of plant in the world, but they are not the only type. There are many other types of plants that are related to the seed plant family.
For example, there is a plant that is similar to a tree, called a conifers. This plant is called the conifer tree and it is found in North America, Europe, Asia, Africa, Australia, New Zealand, South America and South Africa. It is not a true tree because it does not have a trunk.
Instead, it has branches that grow from the top of the tree. The branches are made up of leaves and the leaves are used as food for the plant. Conifer trees can grow up to 20 feet tall. They can also be found on the coast of Africa and Asia.
What specific advantage do seeds provide to seed plants in terms of their reproductive biology?
seeds and pollen were two of the major innovations. Seeds protect the embryo from desiccation and provide it with a store of nutrients to support the early growth of the sporophyte. The seeds can be delayed until growth conditions are optimal. In the absence of sunlight, seed plants are able to reproduce.
The first seeds were made from the seeds of plants such as wheat, barley, oats, rye, and corn.
These seeds are still used today in many countries, including the United States, Canada, Europe, Australia, New Zealand, Japan, South Korea, Taiwan, China, India, Brazil, Mexico, Argentina, Chile, Peru, Colombia, Ecuador, Bolivia, Paraguay, Uruguay, Costa Rica, Panama, El Salvador, Guatemala, Honduras, Nicaragua, Trinidad and Tobago, Jamaica, Dominican Republic, Haiti, Cuba, Venezuela, Guyana, Suriname, Mozambique, Namibia, Swaziland, Tanzania, Zambia, Zimbabwe, Malawi, Kenya, Uganda, Rwanda, Congo, Burundi, Angola, Cameroon, Central African Republic and South Sudan.
The use of seeds is also widespread in Asia, Africa, the Middle East, North America, Latin America and the Caribbean.
