a seed contains a supply of food

Spores are much smaller than seeds. Seeds can be seen but spores can be seen only under the microscope.

Seeds are better then spores because they have a reproductive advantage over spores.

According to Biologists, spores are smaller and lighter than seeds. Spores can only be seen with the use of a machine.

because seeds can store food and nutrients when spores cant, so seeds have a better advantage of surviving in a dry environment.

The main difference between seeds and spores is that spores are not planted in the ground whereas seeds are planted in the ground. Spores fall off of the plants and they are a means of reproducing a plant just like the seeds. Although spores and seeds have similar functions, they have crucial differences. One main difference between seeds and spores is in the size. Spores are much smaller than the seeds. Seeds can easily be seen but spores can only be seen with the help of a microscope. Seeds are fertilized ovules enclosed in a protective coat called testa whereas spores fall off to create a plant somewhere else. Another major difference is that seeds are produced by flowering plants whereas spores are produced by non-flowering plants and fungi. Seeds are enclosed in the fruit of the tree or plant whereas spores are from the underside of the plant. Seeds contain nutrients that are stored in the embryo whereas spores do not store and contain any nutrients. Plants that produce the seeds are known as higher level organisms whereas lower level organisms such as fungus, ferns, mosses ,bacteria and etc. are known to produce spores. Another major difference between the seeds and spores is that seeds are comprised of many cells whereas spores have only a single cell and therefore they are called one celled organisms. Seeds do not need wet lands or excessive water to sprout but spores need swampy or marshy surfaces saturated with water to grow. Spores and seeds are both asexual reproductive structures but spores unlike seeds are produced by plants that have no seeds. Spores have an ability to develop into a new organism whereas it is the embryo in the seed that gives rise to a new plant. Some seeds are haploid or have a single set of chromosomes and some of them are diploid or have two sets of paired chromosomes. Spores are primitive in form and just like seeds are necessary for the ecosystem. Spores help their species to survive the same way as the seeds do but they are not that efficient. Spores can germinate whereas seeds give a head start to the next generations. Summary: 1. Seeds are an efficient way of reproduction whereas spores fall off of a plant to produce next generation organisms. 2. Seeds have an embryo enclosed in a protective coat. 3. Spores are singular organisms whereas seeds have multiple layers. 4. Unlike the spores, the seeds can survive in difficult and less friendly conditions. 5. Spores are too small to be seen by the naked eye.

Spores are lighter (make that less dense).

Spores are not produced until starvation. Thus older cultures are more likely to have spores than new ones.

Some fruit produce more seeds because when they grow in this certain place more seeds are produced in this type of fruit.

Because the success rate for the spore finding the optimal conditions to germinate in are normally low. Therefore in order to improve it's chances of being able to reproduce the spore bearing plant (such as a fern) has to produce more spores to be successful

Seeds do not require water for gamete fertilization; seeds provide protection of the embryo, and sperm is transferred by pollination, usually by animals rather than just depending upon the wind, s do spores.

It is a proven fact that plant seeds produce faster than plant spores.2. Spores are smaller than seeds so therefore they take a longer time to grow and develop -ANNONOMOUS

Wow, that is a hard question.Here are my thoughts. There are typically a lot more spores produced per spore-creating plant than seeds by seed-creating plants. And there is a limited amount of space for things to grow. Of course, spore plants are usually much smaller (in modern times).But there are so many confounding factors that I don't think the question is answerable. Some seeds can grow after being buried for a thousand years. Some seeds are "designed" to be eaten, so there are tons produced.Another important point is that all seed plants also make spores which mature into "mini-plants" which are the ones who ACTUALLY have "sex" and produce seeds. If you want to know more, you should read about alternation-of-generations.

It starts with a seed or spores and slowly turns into maturity. It germinates later. Angiosperms are flowering seeds, so it is covered by a fruit such as apples. Gymnosperms are unprotected seeds,so there are less possibilities to reproduce than angiosperms. Gymnosperms are usually all spores and there are more gymnosperms than angiosperms because of the possibility of growing.

No, fern is a noun. It is a type of vascular plant that reproduces by spores, rather than flowers and seeds.

yes pomegranates do have more seeds than strawberries

The mushroom produces so many spores so that it's able to reproduce and keep the species alive. Imagine that a mushroom produced 10 spores, the chance of all of the spores surviving are MUCH less than how many spores would survive if there were say 1,000 spores.

By a plant? To ensure maximum survival. The more you produce, the more likely it is that some survive. It's evolution at its simplest. Plants usually produce far more seeds than are needed. This is because many seeds don't survive and grow to maturity

Yes the spores are like seeds. They drop off of a fern and onto the ground and sooner or later they sprout and makes a new fern. Spores are not like seeds. They lack a seed coat, endosperm and preformed embryonic parts. In addition spores give rise to the gametophyte generation and seeds give rise to the sporophyte generation. Ferns and mosses do both reproduce by using spores BUT mosses have a reduced almost parasitic sporophyte generation which produces the spores. These spores will produces the gametophyte generation (the green leafy thing we see). The gametophyte produces the sex cells that fuse to make a zygote. This zygote then forms a new sporophyte. With ferns the sporophyte generation is more dominant than the gametophyte. The leafy structure we see is the sporophyte.

Bacterial spores need more nitrogen (for making proteins) than fungal (mold) spores. Also from microbiology class.

Pomegranates have less than all of the fruits, however pumpkin has less seeds than melons and watermelon has more seeds inside than melon.

because the seeds have growed in there.

Because seeds have better chances of survival in adverse environmental conditions than the spores

Club mosses reproduce by spores and spore-bearing structures called strobili rather than through flowers. Sexual reproduction begins when the sporangia, which is the spore producing structure, is mature and is ready to release its spores.

Bacterial spores are far more resistant to disinfectants than non-spore forming bacteria. As a result, bacterial spores are more virulent and therefore more capable of causing disease since they can survive most methods that kill 'normal' bacteria...
