Down: 1) Large organic molecue made of carbon, hydrogen, oxygen, nitrogen and sometimes sulfur.3) The stage of the cell cycle that takes place before cell division occurs.4) The movement of materials through a cell membrane with out using the cell's energy.6) Small openings on a leaf through which oxygen and carbon dioxide can move.8) A green pigment found in the chloroplast of plants, algae, and some bacteria.9) a protein that speeds up chemical reactions such as reactions in a living thing.10) An organism that cannot make its own food.12) A colored chemical that absorbs light.15) The final stage of the cell cycle in which the cell's cytoplasm divides distributing the organelles into each of the two new cells.18) The process by which a cell makes a copy of the DNA in its nucleus.19) a small molecue that is linked chemically to other animal acids to form proteins.20) An energy rich organic compound made of the elements carbon, hydrogen, and oxygen.23) Two or more elements that are chemically combined.25) The stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell.
