Tomato is a plant. The fruit is a familiar vegetable, but the fruit, leaf, and vine are used to make medicine.
Tomato is used for preventing cancer of the breast, bladder, cervix, colon and rectum, stomach, lung, ovaries, pancreas, and prostate. It is also used to prevent diabetes, diseases of the heart and blood vessels (cardiovascular disease), cataracts, and asthma.
Some people use tomato to treat high blood pressure, osteoarthritis, the common cold, chills, and digestive disorders.
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 are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
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.
