Not every organisms which photosynthesize have chloroplasts. Cyanobacteria are prokaryotes, so they lack most organelles defined by a membrane. They don’t have chloroplasts, but they photosynthesize.
Yes. For photosynthesis to occur a chemical reaction has to take place using chloroplasts and sunlight and water, to result in the production of glucose,water and oxygen. If any of the reactants or products are removed, the reaction does not occur. Thus, yes we require chloroplasts to allow an organism to undergo photosynthesis.
The water has a dipole that causes it to act like a magnet, attracting other water molecules to it. Adhesion is the attractive forces that cause water to "stick" to a surface other than its own. ... The salt water has a much lower cohesion than plain water so it's attractive forces are less than plain water.
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms
