Cell Cycle Answer the following:
describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms; Answer the following: The diagram shows cell division in which an error has occurred. Describe the error.
2
The diagram shows cell division in which an error has occurred
The diagram shows cell division in which an error has occurred. Describe the error. A Cell A lacks the cytoplasm necessary to continue normal cell functions. B Cell B contains enough genetic material for the cell to reproduce itself. C Cell A is free of any mutation present in the genetic material of the parent cell. D Cell B lacks instructions for making the proteins necessary for cell metabolism.

Cell Cycle--Engage Question
Why do cells need to divide? Why can’t they just grow into huge cells and perform the functions they are designed to do?
4
Why do cells divide? Growth Development Repair
5
Eukaryotic Cell Cycle You have 100,000,000,000,000!!!!!!!
Did you know? The adult human body produces 2 trillion cells every day. 2,000,000,000,000 Or 25,000,000 every second.
6
What is happening in the
diagram below? CELL CYCLE
7
What are the 3 primary phases
of the Cell Cycle?
8
90% of the Cell Cycle 1. Interphase: A. First Growth Phase (G1):
Rapid Growth Performs routine cell functions Major portion of Cells Life B. Synthesis Phase (S): DNA is copied (synthesized) C. Second Growth Phase (G2): Nucleus prepares to divide Molecules for cell division are produced
9
2. Mitosis of chromosomes Nucleus divides into two nuclei Result:
a. Same number b. Same kind of chromosomes
10
2A. Mitosis Prophase Nuclear Envelope dissolves.
DNA coils, forming chromosomes.
11
2B. Mitosis Metaphase (Middle)
Chromosomes line up in the middle forming pairs attached at centromere.
12
2C. Mitosis Anaphase: One member of each pair (sister chromatid) moves to opposite ends (poles) of the cell.
13
of chromosomes in the nucleus
2D. Mitosis Telophase: Step 3: Two new nuclei form—nuclear membrane forms around both sets of chromatids. Result: a. Same number b. Same kind of chromosomes in the nucleus of both daughter cells
14
3. Cytokinesis: Mitosis & Cytokinesis
Cytoplasm pinches in until the cytoplasm divides completely. Mitosis & Cytokinesis Produces new cells that are identical to the original cells (asexual reproduction).
15
Plant Cytokinesis A cell plate forms between the two nuclei and eventually becomes the ?????? Cell Wall
16
Bacteria & Binary Fission Bacteria (Prokaryotes) reproduce by a process called Binary Fission. Why is the process of binary fission so much simpler than the Eukaryotic cell cycle?
