3 Explanation – Cell Theory

TeacherCrystal Cornelius
Subject AreaComprehensive Science I
Grade Level6
Week #26
Unit of InstructionCell Theory
Standard(s) Taught

SC.6.L.14.2
Investigate and explain the components of the scientific theory of cells (cell theory): all organisms are composed of cells (single-celled or multi-cellular), all cells come from pre-existing cells, and cells are the basic unit of life.

SC.6.N.3.1
Recognize and explain that a scientific theory is a well-supported and widely accepted explanation of nature and is not simply a claim posed by an individual. Thus, the use of the term theory in science is very different than how it is used in everyday life.

SC.6.L.14.3
Recognize and explore how cells of all organisms undergo similar processes to maintain homeostasis, including extracting energy from food, getting rid of waste, and reproducing.

SC.6.L.14.1
Describe and identify patterns in the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems to organisms.

Advanced
SC.912.L.16.14
Describe the cell cycle, including the process of mitosis. Explain the role of mitosis in the formation of new cells and its importance in maintaining chromosome number during asexual reproduction.

 

Learning Targets and Learning Criteria

Students will:
• describe cell theory as:
o all organisms are composed of one or more cells
o all cells come from pre-existing cells
o cells are the basic unit of life
• explain how cell theory is applied to all living organisms
• explain why cell theory is a theory

Students will:
• describe homeostasis as a constant internal condition within cells and organisms
• explore how cells of all organisms undergo similar processes to maintain homeostasis, including:
o getting energy
o removing waste
o reproducing

Students will:
• describe and identify patterns in the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems to organisms, for example:
atom → molecule → cell → tissue → organ → organ system → organism

Advanced:
1. describe the cell cycle, including the process of mitosis. Explain the role of mitosis in the formation of new cells and its importance in maintaining chromosome number during asexual reproduction
