Of the six major plant parts, [n 2] seeds are the dominant source of human calories and protein. [1] A wide variety of plant species provide edible seeds; most are angiosperms, while a few are gymnosperms. As a global food source, the most important edible seeds by weight are cereals, followed by legumes, nuts, [2] then spices.
Food from plants. A plant-based diet is a diet consisting mostly or entirely of plant-based foods. [1] [2] It encompasses a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich [3] plant products such as vegetables, fruits, whole grains, legumes, nuts, seeds, herbs, and spices.
The term pulse is used for the seeds of plants from the Fabaceae family (legumes), such as beans, pea, lentil and chickpea. Pulses supply proteins and form chief source in vegetarian food. Leguminous plants fix nitrogen in root nodules - produced with the help of nitrogen fixing bacteria.
The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and liverworts, 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.
Grain legumes are cultivated for their seeds, [21] for humans and animals to eat, or for oils for industrial uses. Grain legumes include beans, lentils, lupins, peas, and peanuts. [22] Legumes are a key ingredient in vegan meat and dairy substitutes. They are growing in use as a plant-based protein source in the world marketplace.
Foods from plant sources. Plants as a food source are divided into seeds, fruits, vegetables, legumes, grains and nuts. [36] Where plants fall within these categories can vary, with botanically described fruits such as the tomato, squash, pepper and eggplant or seeds like peas commonly considered vegetables. [37]
Runcaria has all of the qualities of seed plants except for a solid seed coat and a system to guide the pollen to the seed. [3] Runcaria was followed shortly after by plants with a more condensed cupule, such as Spermasporites and Moresnetia. Seed-bearing plants had diversified substantially by the Famennian, the last stage
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
