 A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds have been an important development in the reproduction and success of gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates.

Which vegetables have seeds?

This means that tomatoes, pea pods, cucumbers, peppers, squash, and avocados are all fruits, even though many people call them vegetables! Why? You guessed it -- because they all have seeds inside.

How do you get seeds from vegetables?

Each type of plant has its own way of collecting seeds. Pluck the vegetable when the pod begins to dry up and split. Then collect the seeds from the pod and dry it well under shade. Rub ash on the seeds and keep it in an airtight container.

Types of Seeds

Monocotyledonous Seed

A Monocotyledonous seed, as the name suggests, has only one cotyledon. There is only one outer layering of the seed coat.

• Seed Coat: In the seed of cereals such as maize, the seed coat is membranous and generally fused with the fruit wall, called Hull.
• Endosperm: The endosperm is bulky and stores food. Generally, monocotyledonous seeds are endospermic but some as in orchids are non-endospermic.
• Aleuron layer: The outer covering of endosperm separates the embryo by a proteinous layer called the aleurone layer.
• Embryo: The embryo is small and situated in a groove at one end of the endosperm.
• Scutellum: This is one large and shield-shaped cotyledon.
• Embryonal axis: Plumule and radicle are the two ends.
• Coleoptile and coleorhiza: The plumule and radicle are enclosed in sheaths. 

Dicotyledonous Seed

Unlike a monocotyledonous seed, a dicotyledonous seed, as the name suggests, has two cotyledons. 

• Seed coat: This is the outermost covering of a seed. The seed coat has two layers, the outer testa, and the inner tegmen.
• Hilum: The hilum is a scar on the seed coat through which the developing seed was attached to the fruit.
• Micropyle: It is a small pore present above the hilum.
• Embryo: It consists of an embryonal axis and two cotyledons.
• Cotyledons: These are often fleshy and full of reserve food materials.
• Radicle and plumule: They are present at the two ends of the embryonal axis.

How to grow a plant from seed?

Choose a container.

Seed-starting containers should be clean, measure at least 2-3 inches deep,and have drainage holes. They can be plastic pots, cell packs, peat pots, plastic flats, yogurt cups, even eggshells.. Keep in mind that flats and pots take up room, so make sure you have enough sunny space for all the seedlings you start.

Start with quality soil.
Sow seeds in the file, seed-starting mix or potting soil available in nurseries and garden centers. Don't use garden soil, it’s too heavy, contains weeds seeds, and possibly, disease organisms.

Plant at the proper depth.

The general rule of thumb is to cover seeds with soil equal to three times their thickness – but be sure to read the seed packet planting instructions carefully. Some seeds, including certain lettuces and snapdragons, need light to germinate and should rest on the soil surface but still be in good contact with moist soil. Gentle tamping after sowing will help.  After planting your seeds, use a spray bottle to wet the soil again.

Maintain consistent moisture.

Prior to germination, cover your container to help trap moisture inside. Seed-starting kits typically come with a plastic cover. You can also use a plastic bag, but it should be supported so it doesn’t lay flat on the soil. 

Water wisely.
Always use room-temperature water. Let chlorinated water sit overnight so the rine can dissipate or use distilled water. Avoid using softened water. It's important to keep consistently moist, but avoid overwatering, which promotes diseases, that can kill seedlings. 

Keep soil warm.
Seeds need warm soil to germinate.  They germinate slower, or not at all, in soils that are too cool. Most seeds will germinate at around 78°F. Waterproof heating mats, designed specifically for germinating seeds, keep the at a constant temperature. You can buy them in most nurseries and garden centers. 

Fertilize.
Start feeding your seedlings after they develop their second set of true leaves, applying a half-strength liquid fertilizer weekly.

Give seedlings enough light.
Not enough light leads to leggy, tall seedlings that will struggle once transplanted outdoors. In mild winter areas, you can grow stocky seedlings in a bright south-facing window.

Circulate the air.
Circulating air help prevents disease and encourages the development of strong stems. Run a gentle fan near seedlings to create air movement. Keep the fan a distance away from the seedlings to avoid blasting them directly.

Harden off seedlings before transplanting outdoors.
Before moving seedlings outdoors, they need to be acclimatized to their new, harsher surroundings. 

Advantages of seed formation in plants:

• Seeds provide a protective coat so that the embryo plant can develop when it finds a nice piece of soil.
• Seeds are a protective structure that lets a plant embryo survive for long periods of time before it germinates.

Advantages of seed treatment

• Protects germinating seeds and seedlings against soil and seed-borne pathogens/insects.
• Seed germination enhancement.
• Early and uniform establishment and growth.
• Enhances nodulation in legume crop.
• Better than soil and foliar application.

Biological seed treatment?

Biological seed treatment consists of active ingredients that can include microbes like fungi and bacteria, as well as plant extracts and algae extracts. Biological substances are applied to the seed in a powder form or as a liquid.

Chia Seeds

Chia has come a long way since it first sprouted out of funny pottery in TV commercials. These tiny seeds pack in 10 grams of fiber in a 2-tablespoon serving. Chia seeds are easy to add to your favorite dishes. Sprinkle them ground or whole onto cereal, vegetables, or yogurt. Soak them in water to add to cooked cereal, or find a recipe for chia pudding as a healthy and tasty dessert.

Wild Rice

Wild rice is actually a seed – a grass seed. It's higher in protein than most other whole grains and contains 30 times more antioxidants than white rice. Wild rice is extremely versatile and can be substituted for white rice in any dish. It can also be a healthy addition to a salad or soup.

Pumpkin Seeds

Pumpkin seeds are a tasty snack that boasts 16% of your daily iron needs in just ¼ cup. That same ¼ cup will also get you 5 grams of fiber, which is more than most nuts. In addition, pumpkin seeds are a good source of amino acids, protein, and omega-3s, as well as minerals such as zinc and magnesium.

They can be eaten on their own, added to salads, or on top of yogurt. Hemp milk is a good alternative to dairy milk.

Sunflower Seeds

Sunflower seeds are high in healthy fats, as well as: proteins, fiber, phytochemicals, selenium, copper, and magnesium. the richest source of vitamin E.” Aside from salad toppings, you can add sunflower seeds to muffins or bread recipes, in vegetable dishes or stir-fry, into trail mixes, and in cereals or yogurt. 

Sesame Seeds

Despite their tiny size, sesame seeds contain up to 20% protein and lots of fiber. They are rich in the amino acids tryptophan and methionine. Sesame oil is a good choice for salad dressings as it is rich in linoleic and oleic acids, which have a cholesterol-lowering effect. 

Pine Nuts

Pine nuts contain all of the amino acids along with: vitamin A, thiamin, riboflavin, niacin, vitamin E, copper, iron, managanese, and phosphorus.
