seed, fertilized and ripened ovule, consisting of the plant embryo, varying amounts of stored food material, and a protective outer seed coat. Seeds are frequently confused with the fruit enclosing them in flowering plants as in the grains and nuts. True seeds vary in size from the dustlike seeds of some orchids to the large seed contained in the coconut. The period of dormancy undergone by many seeds before germination also varies; the mangrove seed may sprout inside a fruit still hanging on the tree, while a seed of a sacred lotus dated at about 1,200 years and one of a date palm about 2,000 years old have been germinated. Long dormancy in some seeds is ensured by their extremely hard coats, which have to be scratched or split to force sprouting. In plant breeding, the source of pollen for fertilization is carefully controlled to produce the desired qualities in seed; under natural conditions a plant grown from seed may be quite different genetically from its maternal plant.

fruit, matured ovary of the pistil of a flower, containing the seed. After the egg nucleus, or ovum, has been fertilized (see fertilization) and the embryo plantlet begins to form, the surrounding ovule (see pistil) develops into a seed and the ovary wall (pericarp) around the ovule becomes the fruit. The pericarp consists of three layers of tissue: the thin outer exocarp, which becomes the "skin"; the thicker mesocarp; and the inner endocarp, immediately surrounding the ovule. A flower may have one or more simple pistils or a compound pistil made up of two or more fused simple pistils (each called a carpel); different arrangements give rise to different types of fruit. A new variety of fruit is obtained as a hybrid in plant breeding or may develop spontaneously by mutation.

A seed can be the offspring of a fruit and eventually become a fruit. However, it is an interdependant system. If the seed is not eated(because the fruit is appealing) and deposited somewhere else it may not grow, or if the fruit may help the seed by decomposing and making a nurtient rich area to grow in.

I don't know about 2 paragraphs, but a seed is the means by which a living thing will reproduce itself. I the case of palnts, a seed will contain all the genetic information necessary for the plant to grow, eg a sunflower seed. The seed has to draw its nourishment from the ground. A fruit contains the seed, but that that seed is surrounded by the flesh of the fruit. Hope this helps.

Seed and fruit,
peach [Credit: Jack Dykinga/U. S. Department of Agriculture]
respectively, the characteristic reproductive body of both angiosperms (flowering plants) and gymnosperms (conifers, cycads, and ginkgos) and the ovary that encloses it. Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa). Frequently small in size and making negligible demands upon their environment, seeds are eminently suited to perform a wide variety of functions the relationships of which are not always obvious: multiplication, perennation (surviving seasons of stress such as winter), dormancy (a state of arrested development), and dispersal. Pollination and the “seed habit” are considered the most important factors responsible for the overwhelming evolutionary success of the flowering plants, which number more than 300,000 species.

Expand on this:

A seed is a structure found within a fruit (e.g. peas are seeds , the pea pod and its seeds constitute the fruit).

The fruit is often used as an aid to seed dispersal (sycamore wing, coconut husk, explosive gorse pods).

Beware false fruits such as strawberry and apple where what we think of as the fruit was NOT derived from the ovary wall, but from a structure called the receptacle.

Is dependent on the context really. Which is better as a snack - fresh fruit personally. It's tastier and gives you that little bit of sweetness. Which can be better as a snack if you are trying hard to lower back on sugar and lose weight vegetables

A seed, like the "seed" of a man and a woman, creates fruit (a baby). Which contains more seeds to create more fruit.
