What is a "Nucleus"? the structure that forms the surface of a cell separating its contents from the
outside world
an organelle of some eukaryotic cells in which photosynthesis occurs, using the
energy of light to make organic compounds from carbon dioxide and water
a cell organelle that is essential to cell functions including reproduction, contains
the cell's chromosomes, and is enclosed by a membrane
membrane-bound organelles in eukaryotic cells in which cellular respiration
takes place, using oxygen to break down glucose to carbon dioxide and water
and putting the energy into a more readily usable form in ATP molecule
