Carbon cycle
The carbon cycle is the process through which carbon is cycled through the air, ground, plants, animals, and fossil fuels. Large amounts of carbon exist in the atmosphere as carbon dioxide (CO2).
Cell organelles (ribosome, mitochondria, chloroplast, vacuole, lysosome)
Cell organelles: a structure (as a mitochondrion) in a cell that performs a special function
Ribosome: one of numerous small RNA-containing particles in a cell that are sites of protein synthesis
Mitochondria: one of the round or long bodies found in the cytoplasm of cells outside the nucleus that are rich in fats, proteins, and enzymes and are important centers of metabolic processes which use oxygen and produce energy
Chloroplast: a cellular part that contains chlorophyll and is the location of photosynthesis
Vacuole: a cavity in bodily tissues or in the cytoplasm of a cell that is usually filled with fluid
Lysosome: A membrane-bound organelle in the cytoplasm of most cells containing various hydrolytic enzymes that function in intracellular digestion.
