You've shown time and time again that you truly know all the answers. so i will turn to you for another solution... where do seeds from lettuce, radishes, and carrots come from?

A: Dear Vermilion Opposable Digit,
Ah, we at the 100 Hour Board love when our readers begin thinking more about their food (we also love the unabashed ego-stroking). There is so much wonder to be found in what we eat. Amazing things really. For example, that broccoli, cabbage, brussel sprouts, broccoli rabe, cauliflower, etc. are all really just slightly differently developed plants. Man has been at it for quite a while.
So before we get too far, lettuce take a look at your question. A little anatomy is needed first. Plants have roots, stems, leaves and flowers - usually. A vegetable is really the part of a plant we eat that is not either fruit or seed (like wheat or rice). Fruits come from the plants ovary and surrounds the seeds. And then we use herbs (green parts) and spices (non-green parts). Vegetables are leaves, stems, pods, roots, storage vessels, bulbs, etc. Fruits are unique in that they are specifically grown to be yummy, in order to spread seeds. Veggies are things we have either become used to eating (bitterness), or we alter in some way to make them safe (soak, cook, beat, pound, etc.)
So in the case of all vegetables, there is another part of the plant that is an ovary and produces seeds. These then grow into other vegetables. We usually eat around these fruits, or eat the veggie before the flowers/seeds develop. There are few plants to we eat almost everything on it, usually we develop a breed for a specific part. Like beets and chard are the same plants, but we develop them differently to get good, big beets, or large leaves.
Take lettuce then. If left to grow it sprouts flowers - lots of them - this is called bolting. Of course we eat lettuce before it gets to this point, usually. Dandelion greens are delicious, and you are quite familiar with the flower.
Radishes are not roots - although some will dangle off. They are mostly a swollen stem, like a turnip, that isn't starchy like potatoes. But radishes are relatives of the cabbage family (even mustards too - which you may be more familiar with the seeds and flowers). They get flowers too - nice white ones with four leaves.
What does this mean for veggies then? You usually harvest - and kill - the ones you eat, and then dedicate another crop for developing seeds. There are a few perennials - like rhubarb, asparagus (grow from underground rhizomes) and Good King Henry. But many of these are not grown now because it is easier to harvest plants completely than parts of them.
Fruits are perennial, essential to the plants reproduction. So things we think of as having seeds (or eating them) are fruits: peas, beans, tomatoes, squash, artichoke - ok really a flower, etc. Fruits come from the plants ovary - usually in a flower - that has 4 steps: is fertilized (male pollen + female ovule - thank you bees!), fruit development, storage growth and ripening. There are exceptions. And thus are born "seedless" fruits.
Seedless plants are either 1) bred to be sterile - chromosomes prevent seed growth, like melons (though the sterile triploid plant must grow next to the unsterile diploid plant to get pollen) or 2)they are created without fertilization - like bananas, pineapples, grapes and naval oranges.
The issue with seedless fruits is they are a target for parasites or diseases b/c they are usually clones of each other.
Plant cultivation for food is a fascinating topic. We take for granted the years of cultivation, technology, breeding and science in what we eat. The 100 Hour Board for one is very interested in getting their own garden growing. But Community Supported Agriculture is also a good idea.
So - happy eating. Olive you to your food.

I can definitely see that shameless flatery is the only way to get a question answered in 100 hours around here!
Very interesting...and a bit confusing.
From old people jokes to pictures of Obama not pledging allegiance to the flag...where do forward e-mails originate from? Who sits down and decides, "I'm going to create this e-mail that will be forwarded across the world"?
