DNA Science Cells divide into two new cells by the process of ______________ . a. mitosis b. chromosomes c. homologous chromosomes d. DNA Science Right before mitosis occurs, the ___________make copies of themselves. a. mitosis b. chromosomes c. homologous chromosomes d. DNA Science In the process of _____________ , cells bring in large particles. a. exocytosis b. fermentation c. endocytosis d. cellular respiration Science In the process of ______________________, cells remove large particles. a. exocytosis b. fermentation c. endocytosis d. cellular respiration Science When oxygen breaks down food to release energy, it is called ____________. a. exocytosis b. fermentation c. endocytosis d. cellular respiration Science Breaking down food for energy without using oxygen is _______________. a. exocytosis b. fermentation c. endocytosis d. cellular respiration Science Look at the figure. What two processes does it show? Science Look at the figure. What are released during cellular respiration? Science Chromatids separate and move to opposite sides of the cell. Science The chromosomes line up along the equator of the cell. Science Before mitosis begins, chromosomes are copied. Science The nuclear membrane forms around the two sets of chromosomes, and the chromosomes unwind. Mitosis is complete. Science Mitosis begins. The nuclear membrane dissolves. Chromosomes condense into rodlike structures. Science Name the cell structures that are needed for photosynthesis and the cell structures that are needed for cellular respiration. Chloroplasts are needed for photosynthesis. Cellular respiration requires mitochondria. Science Describe the three stages of the cell cycle of a eukaryotic cell. The first stage is cell growth and copying of DNA (duplication.) The second stage is mitosis, and the third stage is cytokinesis (cell division.) Science
