Cell Reproduction

Cell Reproduction – Cell Cycle 4. 2 1. Cell reproduction in Eukaryotic _____cells is more complex than cell reproduction in Prokaryotic _____ cells. 2. The life cycle of a cell or Cell ____ is cycle _________________ The sequence of events in the growth and division of a eukaryotic cell ___________.

Cell Cycle 3. The cell cycle has ____ main phases: 2 A. Interphase B. M-Phase

A. Interphase - the period between two divisions of Grows a eukaryotic cell during which the cell _____ Cell Division and prepares for ________. 1 st Growth phase a. G 1 – This is the __________. Cells mature & increase in size by making more cytoplasm & organelles while carrying normal metabolic activities. b. S – This is the ___________. Synthesis phase The genetic material of the cell (DNA) is copied/replicated. c. G 2 – This is the ___________. 2 nd Growth phase Cell continues to grow, and makes all the structures (i. e. organelles) needed for cell division.

B. M-Phase/Mitosis & Cytokinesis M-Phase - The portion of the cell cycle in Nucleus which the ______divides (called Cytoplasm divides Mitosis _____) and the ______ Cytokinesis (called ______) 4. Diagram the Cell Cycle. Label each of its phases: 1. Interphase a) G 1 b) S c) G 2 2. Mitotic (M) phase: a) Mitosis b) Cytokinesis

Reproduction Rates 5. Prokaryotic cells reproduce much ______ than Faster eukaryotic cells. A. A prokaryotic (bacterium) cell divides once every 20 -30 minutes __________. B. A eukaryotic (human skin) cell divides once 24 hours every ______.
