LS.2 d - Cell Division

The student will investigate and understand that all living things are composed of cells. Key concepts include
d) cell division.

Bloom's Levels:  Analyze; Understand

Adopted: 2010

BIG IDEAS

  • All cells come from other cells.
  • All living things reproduce to produce more of their own kind.
  • Reproduction is a characteristic of living things and is essential for the survival of species.


  • I can explain how tumors grow.

UNDERSTANDING THE STANDARD

  • Cells go through a life cycle known as the cell cycle. The phases of the cell cycle are interphase, mitosis, and cytokinesis. (Although it is appropriate for students at this level to learn to recognize the stages of the cell cycle and mitosis, an exploration of the individual stages of meiosis may be reserved for high school Biology.)
  • The purpose of mitosis is to produce new cells for growth and repair that are identical to the parent cell. The purpose of meiosis is to produce reproductive (sex) cells that carry half the genetic material of the parent.

ESSENTIALS

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

d)  sequence the steps in the cell cycle, including the phases of mitosis.

differentiate between the purpose of mitosis and meiosis.

a, b, c, d)  design an investigation from a testable question related to animal and plant cells. The investigation may be a complete experimental design or may focus on systematic observation, description, measurement, and/or data collection and analysis. An example of such a question is: “Do onion cells vary in shape or structure depending on where they are found in the plant?”
