As humans, we know our range of color vision stems from red to violet. Predators like wolves can see more in the infrared range so they can track prey better at night by the prey's heat signature. Many insects can see into the ultraviolet region of the electromagnetic spectrum. ...

Although not considered in detail here, higher plants also discriminate against the heavier isotopes of Si during phytolith formation and may also represent palaeoenvironmental archives. The key controls on lake and ocean [dSi] and δ30Si distributions are conceptually understood (e.g. de Souza et...
Plants that always turn purple from the beginning may have lower THC. This may possibly be because the “tan” of the purple is preventing the plant from getting as might light as it could have. For some strains, buds appear purple from the beginning, and never go through a “green stage...
At the north end of the sprawling Papago Park is a glorious botanical garden collecting desert species from around the world. Of the 4,000 taxa represented at the Desert Botanical Garden, one-third are native to the Sonoran, around Phoenix. There are 50,000 plants in all, counting large ...
Carotenoids are lipophilic isoprenoid pigments with a common C40H56 core chemical structure that are naturally synthesized by many plants, algae, bacteria, and fungi. Humans and animals cannot synthesize carotenoids de novo and must obtain them solely th
Of course, evergreen trees continue to photosynthesize all year, so they do not lose their needle-like leaves in the fall, remaining green because they still need chlorophyll to collect energy from the sun in the winter. Related Articles Why Do Leaves Change Color In Fall? How Does the ...
In eukaryotes (plants, fungi and animals), many of these ribosomes are attached to a "highway-like" membrane-heavy feature called theendoplasmic reticulum. This comes in two types, "smooth" and "rough." The cells of the liver, ovaries and testes have a high density ofsmooth endoplasmic ...
There are a few tables inside, but the sensation of escaping the city is better experienced from one of the thickly cushioned chairs next to tables arranged between large umbrellas and potted plants. If you’re lucky, you can snag a spot for two in one of a few intimate greenhouse-like ...
In reality, Venus flytraps, pitcher plants, and bladderworts aren’t so different from sunflowers or apple trees: their actual “food,” or energy, comes from the Sun. Carnivory doesn’t replace photosynthesis for these plants, which convert light into chemical energy just like their le...
