Answer: Chlorophyll is a green chemical inside chloroplasts. It carries out photosynthesis, which makes energy for a plant using sunlight. In fact, when you get a grass stain on your clothes, the green stuff is chlorophyll.
Answer: Chlorophyll is what plants use to conduct photosynthesis. Chlorophyll makes plants look green so only green plants will have chlorophill in them. Therefore in answer to your question it will just be leafy greens that have chlorophyll in them!
Answer: yes. ex: cactus. True plants (as opposed to fungus) have chlorophyll in their leaves. They carry out photosynthesis like any other plant, but other chemicals in the leaves mask the chlorophyll, giving the leaf a non-green hue. There is also a species of parasitic dodder (Cuscuta europaea) which does not photosynthesize, and depends on other plants for nutrition.
Answer: We need to move to electric motors, or perhaps nuclear powered engines. Neither of these would emit carbon dioxide. At present the best way to store electricity is in batteries, which are heavy. If we have a breakthrough in electricity storage, then electric planes might be possible.A: HOTOL 1984 till now. There were plans for an air breathing aircraft, by Rolls Royce. The engine was technically a liquid hydrogen/ liquid oxygen design. However this vehicles funding ceased. New developments in this technology are not dead yet. Look for HOTOL on the web if you are interested in no CO2s. You can reduce the carbon emmisions caused by planes by maby having lighter planes that are smaller and hold less passengers e.g. sending out more flights but holding less passengers and luggage. Less people on board ?
By growing more and more trees to absorb the carbon from the atmosphere.
By using trains and buses where possible rather than planes.
By developing aircraft engines that have a much lower carbon footprint that at present.
Answer: Why were your house plants outside? If they are outside they are not house plants. If they are tender and will not survive the winter slow down on the water and let them rest. In the SPRING INCREASE THE WATER AND THEY WILL FLOURISH FOR NEXT YEAR .
