THE PLANT CELL What Are the Phases of the Cell Cycle? Specific Metabolic Events Occur in Each Cell Cycle Phase. Every plant is constructed from small compartments called cells. Each cell is a living individual, possessing the basic characteristics of life, including movement, metabolism, and the ability to reproduce.
During interphase, most cells go through three stages—rapid growth and replication of the organelles; replication of DNA, the genetic information in a cell; and preparation for cell division.
Cell division is important to one-celled organisms, too—it’s how they repro-duce themselves, as shown in Figure 1. Cell division isn’t as sim-ple as just cutting the cell in half, so how do cells divide? A living organism has a life cycle.
What are the key phases of the cell cycle, and what occurs in each phase? The cell cycle consists of four major phases: G1, S, G2, and M phase. In the G1 phase, the cell grows and prepares for DNA replication. During the S phase, DNA is replicated, resulting in the duplication of chromosomes.
The diagram below shows six cells in various phases of the cell cycle. Note the cells are not arranged in the order in which the cell cycle occurs. Use the diagram to answer questions 1-7. _____1. Cells A & F show an early and a late stage of the same phase of the cell cycle. What phase is it? prophase _____2.
The document describes the cell cycle and the key events of each phase: 1) It defines the main phases - interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. 2) Matching questions identify the key events like chromosome condensation and separation that occur in each phase.
CELLULAR REPRODUCTION AND THE CELL CYCLE Chapter Outline 9.1 The Cell Cycle A. Stages 1. The cell cycle is an orderly set of stages from first division to the time the daughter cells divide. 2. When a cell is going to divide, it grows larger, the number of organelles doubles, and the DNA replicates. B. Interphase 1.
