It was adapted by flowers to orient pollinators leading to an example of co-evolution. [8] UV light allows them to broadcast a guide to where their pollen is located. [4] Due to unique life characteristics and morphology of flowers, pollinators are more effective at taking the pollen and spreading it to other flowers of the same species. [3]
It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. [1] Nyctinasty is found in a range of plant species and across xeric , mesic , and aquatic environments, suggesting that this singular behavior may serve a variety of ...
Later they developed some of the first transistorized warning lights (Visi-Flash trademark) using standard 6-volt lantern batteries, which either blinked in timed intervals or had a steady light. Gerry Dietz reestablished the company in Hong Kong and as of 1956, they moved their production outside of the United States, first to Hong Kong until ...
Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin.
NFL Commissioner Roger Goodell on Wednesday said the league is aware of a lawsuit that accuses musician Jay-Z of rape but said it is not impacting the NFL's partnership with the rap mogul's Roc ...

It's nearly here. After an exciting and drama-filled season featuring grueling challenges, complicated alliances and shocking betrayals, the first part of the finale for Season 47 of "Survivor ...
The detailed study of reproductive structures in plants led to the discovery of the alternation of generations, found in all plants and most algae, by the German botanist Wilhelm Hofmeister. This discovery is one of the most important made in all of plant morphology, since it provides a common basis for understanding the life cycle of all plants.
