Lysosome - CORRECT ANSWER-Membranous sac that contains digestive enzymes. Nuclear envelope - CORRECT ANSWER-Separates nuclear contents from cytoplasm Nucleus - CORRECT ANSWER-Spherical organelle that contains chromatin and nucleolus. Interphase - CORRECT ANSWER-Mitosis: Cell has passed the restriction checkpoint and completed DNA replication as well as replication of centroles and mitochondria and synthesis of extra membrane. Prophase - CORRECT ANSWER-Mitosis: Chromosomes condenzse and become visible. Nuclear envelope and nucleolus disperse. Spindle apparatus forms. Metaphase - CORRECT ANSWER-Chromosomes align along equator or metaphase plate of cell. Anaphase - CORRECT ANSWER-Sister chromatids seperated to opposite poles of cell. Events begin which lead to cytokinesis. Telophase - CORRECT ANSWER-Chromosomes complete migration toward centrioles. Chromosomes unwind from rods into threadlike chromatin when they approach one another.
