How does carbon dioxide enter a plant?Photosynthesis:Photosynthesis is the process by which a photosynthetic cell (e.g. in a plant) takes in water and carbon dioxide and yields glucose sugar and molecular oxygen
How Do Oceans Absorb Carbon Dioxide? Scientists Find CluesAre you grateful that it's not 850 degrees Fahrenheit outsideright now, like the surface of...Chowdhury, Sudeshna
If the soil is not porous, carbon dioxide does not leave the seed, and it will suffocate. If the optimal conditions are met, the seed absorbs more and more water (imbibition), swells up, and bursts! Once the seed coat bursts open, a primary root emerges, known as the radicle. In alm...
Carbon dioxide (CO2) is necessary to sustain certain plant life, but it also has a reputation for causing harmful environmental effects. Explore CO2's life-giving role in photosynthesis, and understand global concerns over rising CO2 concentrations in the air and oceans. Related...

Plants absorb water through their roots. 空气中含有二氧化碳 carbon dioxide, 二氧化碳通过植物叶片表皮上气孔进入植物。 你可能会说:我也没看见气孔呀! 气孔只有头发丝的五分之一大小。 水的氢和氧原子与来自二氧化碳的碳结合 形成碳水化合物, 也就是糖 sugar。
How is carbon-14 used to date fossils? All living things absorb carbon from the atmosphere, including an amount of radioactive carbon-14. When a plant or animal dies, it stops absorbing carbon. But the radioactive carbon-14 it has accumulated continues to decay. Scientists can measuring the...

During its lifetime, a typical energy-saving lamp will stop about a tonne of carbon dioxide from entering the atmosphere and pay for itself many times over. [2] So it's good for your pocket and kind to the Earth as well. There are two quite different kinds: CFLs (compact fluorescent ...
