Scientists Scrutinize A Plant to Uncover Some Genetic SecretsRobert C. Cowen, writer of The Christian Science Monitor
Through cloning scientists can develop “super” fruits and vegetables of superior (更好的) nutritional quality. This could make for a healthier population overall. This is already being done through selective pollination (授粉), and genetic cloning could take it to the next level. By plant cloni...
In past decades, plant scientists have studied plant sporoderm chemistry extensively. It was widely accepted based on chemical and molecular genetic analysis that sporopollenin contains phenolics and polyhydroxylated aliphatics that are covalently coupled by ether and ester bonds34. However, the chemical...
Science in the community: how can we ensure that the varied goals and needs of our diverse societies are understood and fulfilled by plant scientists? Food security: how do we leverage existing genetic diversity to create climate-resilient crops?
根据第一段“Scientists have figured out how to get large amounts of oil from duckweed, one of nature’s fastest-growing water plants.”(科学家们已经找到了从浮萍中提取大量油的方法,浮萍是自然界中生长最快的水生植物之一。)可知,从浮萍中可以提炼出植物油。故选A项。 (2)题详解: 主旨大意题。
