BIO.5 a-c - Cell Reproduction

The student will investigate and understand common mechanisms of inheritance and protein synthesis. Key concepts include
a) cell growth and division;
b) gamete formation; and
c) cell specialization.

Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • All living things reproduce to produce more of their own kind.  
  • All cells come from other cells.

  • I can explain how tumors grow.
  • I can explain why different organs perform different tasks.
  • I can justify why I look like others in my family.

UNDERSTANDING THE STANDARD

  • All living cells come from other living cells. A typical cell goes through a process of growth, development, and reproduction called the cell cycle. 
  • Mitosis produces two genetically identical cells. During mitosis, the nucleus of the cell divides, forming two nuclei with identical genetic information. Mitosis is referred to in the following stages: prophase, metaphase, anaphase, and telophase. 
  • The many body cells of an organism can be specialized to perform different functions, even though they are all descended from a single cell and contain essentially the same genetic information.

ESSENTIALS

In order to meet this standard, it is expected that students will

a)  create a diagram to model the stages of mitosis and explain the processes occurring at each stage.

     compare and contrast the process of mitosis and meiosis and determine under which conditions each process will occur.

b)  create a diagram to model the stages of meiosis and explain the processes occurring at each stage.

c)  describe the importance of cell specialization in the development of multicellular organisms.
