In a particular plant, green seed color is dominant to yellow seed color. If two Heterozygous green seed plants are crossed, what percent of the offspring would be green?

Regardless of how much CO2 they soak up, wild plants are a key ally in our quest to make civilization sustainable. Rather than just expecting them to protect us, we should focus on protecting them — not just because they might soften the blow of climate change, but also because plants offer many other "ecosystem services" that benefit humanity. Beyond absorbing CO2, for example, plants can release atmosphere-cooling aerosols, clean up toxic fumes and produce life-saving medicines.

"I really hope people can appreciate how much nature has been doing for us,". "Nature is trying to mitigate the consequences of our actions. We should appreciate that and protect plants. There are so many plant species that are doing a service to mankind, yet we have not been studying them. We don't even know how they are doing in the natural environment. If they go extinct, we would miss a lot of knowledge that could have been gained. We need to protect plants and protect nature."
