But such an idea is untrue, according to a new opinion article. Plant biology is complex and fascinating, but it_____(5)so greatly from that of animals that so-called_____(6)of plants intelligence is inconclusive, the authors wrote.
Beginning in 2006, some scientists have_____(7)that plants possess neuron-like cells tha

This_____(11)makes sense if you simplify the workings of a complex brain,_____(12)it to an array of electrical pulses; cells in plants also communicate through electrical signals._____(13), the signaling in a plant is only_____(14)similar to the firing in a complex animal brain, which is more than "a mass of cells that communicate by electricity." Taiz said.
"For consciousness to evolve, a brain with a threshold_____(15)of complexity and capacity is required," he_____(16)"Since plants don't have nervous systems, the_____(17)that they have consciousness are effectively zero."
And what's so great about consciousness, anyway? Plants can't run away from_____(18). So investing energy in a body system which_____(19)a threat and can feel pain would be a very_____(20)evolutionary strategy, according to the article.

Text 1
People often complain that plastics are too durable. Water bottles, shopping bags, and other trash litter the planet, from Mount Everest to the Mariana Trench, because plastics are everywhere and don't break down easily. But some plastic materials change over time. They crack and frizzle. They "weep" out additives. They melt into sludge. All of which creates huge headaches for institutions, such as museums, trying to preserve culturally important objects. The variety of plastic objects at risk is dizzying: early radios, avant-garde sculptures, celluloid animation stills from Disney films, the first artificial heart.
