Plants are the ultimate source of food and metabolic energy for nearly all animals, which cannot manufacture their own food. Besides foods (e.g., grains, fruits, and vegetables), plant products vital to humans include wood and wood products, fibers, drugs, oils, latex, pigments...
Green plants produce their own food through photosynthesis. They are called producers. Conversely, animals and humans are consumers. They get all of their food from plants, either directly or indirectly. In fact, the larger part of theworld’s populationgets over 80% of its food directly from ...
They also produce both fertile pollen, for reproduction, and sterile pollen rich in nutrients for birds and insects. Butterflies and bees can detect ultraviolet light. Flowers that attract these pollinators usually display a pattern of low ultraviolet reflectance that helps them quickly locate the ...
Consider this – mosquitoes can smell or sense carbon dioxide that is completely non-fragrant to humans. Maybe we should be looking at non-fragrant plants to repel mosquitoes? Do Fragrant Plants Repel Mosquitoes? The citronella plant, also called citronella grass, does not repel mosquitoes. It gi...
The shoots, the only edible parts, are at their best just before and during mid-spring, when they're abundant, although you can still find a few shoots that haven't leafed out well into early summer. The tree flowers in late summer and the poisonous berries ripen in the fall. Food ...
wherein one daughter cell is programmed to acquire a specialized fate while the other retains its stem cell identity. The asymmetry of mammalian stem cells has been, in most cases, established during embryogenesis. Embryonic stem cells are pluripotent, i.e. can produce all three germ layers, ec...
On a more positive note, dinoflagellates can exhibit bioluminescence and produce dreamlike scenes of people, boats, or dolphins moving through the water at night creating glowing trails. The dinoflagellates have a more serious role as the symbionts (or, zooxanthellae) of corals. Unfortunately ...
The remains of a simple pitted perforated vessel can be seen along the length of one of S3.S12′s fibers (Fig. 4.B). In subsample S3.S12, there are plausible cell bodies similar to those found in comparative studies with Populus sp. (Fig. 4.C) which are uniseriate and simply ...

Plant parts that can produce yellow dye include the rhizomes of Curcuma longa, the fruits of Gardenia jasminoides, and the flowers of Buddleja Officinalis. According to different seasons, people choose one of the above plants to make yellow dye liquor. The dyeing process is relatively simple. ...
