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: This is correct. The chlorophyll is a pigment that, in addition to making the leaf green, it allows photosynthesis which is the process of using sunlight to convert carbon dioxide to oxygen in addition to making proteins and sugars. All life on earth is reliant on photosynthesis.
Answer: I think it could be possible to extract chlorophyll from plants or create it artificially, and maybe turn it into a paint, but im not sure how a car would run on glucose, unless you made it burn, but photosynthesis does produce oxygen.
Answer: Directly inside a nuclear explosion the temperature is several million degrees. At this temperature everything turns to plasma (highly ionized gas). You would not become ash, dust, or get charred; you would vaporize to gas and most of the electrons would be stripped from the atoms of the gas. Sometime later as this material cooled your atoms would condense out on tiny particles that had been lifted by the updraft into the mushroom cloud and you would become part of the radioactive fallout.
Note, you could not be at the exact center of a nuclear explosion, as this point is inside the physics package of the device which is usually much smaller than a human.
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!
