Seeds in the context of Pollen

A fruit tree is a tree which bears fruit that is consumed or used by animals and humans. All trees that are flowering plants produce fruit, which are the ripened ovaries of flowers containing one or more seeds. In horticultural usage, the term "fruit tree" is limited to those that provide fruit for human food. Types of fruits are described and defined elsewhere (see Fruit), but would include "fruit" in a culinary sense, as well as some nut-bearing trees, such as walnuts.

The scientific study and the cultivation of fruits is called pomology, which divides fruits into groups based on plant morphology and anatomy. Some of those groups are pome fruits, which include apples and pears, and stone fruits, which include peaches/nectarines, almonds, apricots, plums and cherries.

A hoe is an ancient and versatile agricultural and horticultural hand tool used to shape soil, remove weeds, clear soil, and harvest root crops. Shaping the soil includes piling soil around the base of plants (hilling), digging narrow furrows (drills) and shallow trenches for planting seeds or bulbs. Weeding with a hoe includes agitating the surface of the soil or cutting foliage from roots, and clearing the soil of old roots and crop residues. Hoes for digging and moving soil are used to harvest root crops such as potatoes.

A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like. The cones of Pinophyta (conifer clade) contain the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name 'cone' derives from Greek konos (pine cone), which also gave name to the geometric cone. The individual plates of a cone are known as scales. In conifers where the cone develops over more than one year (such as pines), the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale, is called an umbo, while the second year's growth is called the apophysis.

The male cone (microstrobilus or pollen cone) is structurally similar across all conifers, differing only in small ways (mostly in scale arrangement) from species to species. Extending out from a central axis are microsporophylls (modified leaves). Under each microsporophyll is one or several microsporangia (pollen sacs).

Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, in many cases leaving the seeds damaged and not viable. Granivores are found across many families of vertebrates (especially mammals and birds) as well as invertebrates (mainly insects); thus, seed predation occurs in virtually all terrestrial ecosystems.

Seed predation is commonly divided into two distinctive temporal categories, pre-dispersal and post-dispersal predation, which affect the fitness of the parental plant and the dispersed offspring (the seed), respectively. Mitigating pre- and post-dispersal predation may involve different strategies. To counter seed predation, plants have evolved both physical defenses (e.g., shape and toughness of the seed coat) and chemical defenses (secondary compounds such as tannins and alkaloids). However, as plants have evolved seed defenses, seed predators have adapted to plant defenses (e.g., ability to detoxify chemical compounds). Thus, many interesting examples of coevolution arise from this dynamic relationship.

Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.

Cotton seed has a similar structure to other oilseeds, such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability.

Secondary succession is the secondary ecological succession of a plant's life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil. Many factors can affect secondary succession, such as trophic interaction, initial composition, and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal, micro climate; landscape structure (habitat patch size and distance to outside seed sources); bulk density, pH, and soil texture (sand and clay).

Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as soil is already present, and seeds, roots, and the underground vegetative organs of plants may still survive in the soil.

A granary, also known as a grain house and historically as a granarium in Latin, is a post-harvest storage building primarily for grains or seeds. Granaries are typically built above the ground to prevent spoilage and protect the stored grains or seeds from rodents, pests, floods, and adverse weather conditions. They also assist in drying the grains to prevent mold growth. Modern granaries may incorporate advanced ventilation and temperature control systems to preserve the quality of the stored grains.

A cryptogam (scientific name Cryptogamae) is a plant, in the broad sense of the word, or a plant-like organism that shares similar characteristics, such as being multicellular, photosynthetic, and primarily immobile, that reproduces via spores rather than through flowers or seeds.

This broader definition can include algae, fungi, and certain bacteria (like cyanobacteria), even though they may belong to different biological kingdoms.

A milkshake (sometimes simply called a shake) is a sweet beverage made by blending milk, ice cream, and flavorings or sweeteners such as butterscotch, caramel sauce, chocolate syrup, or fruit syrup into a thick, sweet, cold mixture. It may also be made using a base made from non-dairy products, including plant milks such as almond milk, coconut milk, or soy milk. Dry ingredients such as whole fruit, nuts, seeds, candy, or cookies may be incorporated.

Milkshakes originated in the United States around the turn of the 20th century and gained widespread popularity after the introduction of electric blenders in the following decades. During this period, ice cream shops became popular social gathering spots for young people, and milkshakes came to symbolize the simplicity and innocence of youth culture.

Scale armour is an early form of armour consisting of many individual small armour scales (plates) of various shapes attached to each other and to a backing of cloth or leather in overlapping rows. Scale armour was worn by warriors of many different cultures as well as their horses. The material used to make the scales varied and included bronze, iron, steel, rawhide, leather, cuir bouilli, seeds, horn, or pangolin scales. The variations are primarily the result of material availability.

Scale armour – a defence of great antiquity – began in the Middle East. The earliest representation is the tomb of Kenamon, who lived in Egypt in the reign of Amenhotep II (1436–1411 BC).

Flying squirrels (scientifically known as Pteromyini or Petauristini) are a tribe of 50 species of squirrels in the family Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail.

Molecular studies have shown that flying squirrels are monophyletic (having a common ancestor with no non-flying descendants) and originated some 18–20 million years ago. The genus Paracitellus is the earliest lineage to the flying squirrel dating back to the late Oligocene era. Most are nocturnal and omnivorous, eating fruit, seeds, buds, flowers, insects, gastropods, spiders, fungi, bird's eggs, tree sap and young birds. The young are born in a nest and are at first naked and helpless. They are cared for by their mother and by five weeks are able to practice gliding skills so that by ten weeks they are ready to leave the nest.

In biology, a propagule is any material that functions in propagating an organism to the next stage in its life cycle, such as by dispersal. The propagule is usually distinct in form from the parent organism. Propagules are produced by organisms such as plants (in the form of seeds or spores), fungi (in the form of spores), and bacteria (for example endospores or microbial cysts).

In disease biology, pathogens are said to generate infectious propagules, the units that transmit a disease. These can refer to bacteria, viruses, fungi, or protists, and can be contained within host material. For instance, for influenza, the infectious propagules are carried in droplets of host saliva or mucus that are expelled during coughing or sneezing.

Lemon basil, hoary basil, Thai lemon basil, or Lao basil, (Ocimum × africanum) is a hybrid between basil (Ocimum basilicum) and American basil (Ocimum americanum). The herb is grown primarily in northeastern Africa and southern Asia for its fragrant lemon scent, and is used in cooking.

Lemon basil stems can grow to 20–40 cm (8–20 in) tall. It has white flowers in late summer to early fall. The leaves are similar to basil leaves, but tend to be narrower with slightly serrated edges. Seeds form on the plant after flowering and dry on the plant.

Brazil nut (Bertholletia excelsa) refers to a South American tree in the family Lecythidaceae as well as the tree's commercially-harvested edible seeds. It is one of the largest and longest-lived trees in the Amazon rainforest. The fruit and its nutshell – containing the edible nut – are relatively large and weigh as much as 2 kg (4.4 lb) in total. As food, Brazil nuts are notable for diverse content of micronutrients, especially a high amount of selenium. The wood of the Brazil nut tree is prized for its quality in carpentry, flooring, and heavy construction.

In 2023, Brazil and Bolivia combined produced 91% of the world total of Brazil nuts.
