TFSD Unwrapped Standard
Grade 10 - Biology
Power Standard (s) Reference: Standard 5 – Cell Division
State Standard:
Goal 1.4: Understand the Theory that Evolution is a Process that Relates to the Gradual
Changes in the Universe and of Equilibrium as a Physical State
Reference to 7.S.3.2.1
Goal 1.5: Understand Concepts of Form and Function
Standard 3: Biology
Students explain the importance of cells as they relate to the organization and structure of
complex organisms, differentiation and specialization during development, and the chemical
reactions necessary to sustain life. Students describe the functions of cell structures. Students
use the theory of evolution to explain diversity of life.
Goal 3.1: Understand the Theory of Biological Evolution
9-10.B.3.1.1 Use the theory of evolution to explain how species change over time.
9-10.B.3.1.2 Explain how evolution is the consequence of interactions among the
potential of a species to increase its numbers, genetic variability, a finite
supply of resources, and the selection by the environment of those offspring
better able to survive and reproduce.
Goal 3.3: Understand the Cell is the Basis of Form and Function for All Living Things
9-10.B.3.3.3 Explain how cells use DNA to store and use information for cell functions.
9-10.B.3.3.4 Explain how selective expression of genes can produce specialized cells
from a single cell.
Goal 5.2: Understand the Relationship between Science and Technology
9-10.B.5.2.1 Explain how science advances technology.
9-10.B.5.2.2 Explain how technology advances science.
9-10.B.5.2.3 Explain how science and technology are pursued for different purposes.
National Standards
C.1.a Cells have particular structures that underlie that underlie their functions.
C.1.c Cells store and use information to guide their functions.
C.1.d Cell functions are regulated
C.1.f Cells can differentiate, and complex multicellular organisms are formed as a highly
organized arrangement of differentiated cells.
C.2.b Most of the cells in a human contain two copies of each of 22 different chromosomes.
In addition, there is a pair of chromosomes that determine sex.

Be able to do (Verb Phrases)
Explain the problems that growth causes for cells.
Describe how cell division solves the problems of cell growth.
Name the main events of the cell cycle.
Describe what happens during the four phases of mitosis.
Identify a factor that can stop cells from growing.
Describe how the cell cycle is regulated.
Explain how cancer cells are Name from other cells.
Identifying Big Ideas from Unwrapped Standards:
1. There are different forms of asexual reproduction that allow cells to produce offspring.
2. Asexual reproduction produces offspring genetically identical to parents.
3. The nucleus divides to form two identical nuclei.
Essential Questions from Big Ideas to Guide Instruction and Assessment:
1. How do cells divide to make more cells?
2. How do parents and offspring produced by asexual reproduction compare?
3. What happens to the nucleus during mitosis?
Possible Topics or Context: (what you will use to teach the concepts and skills-particular
unit, lessons or activities)
 Pre-assessment
o Create a wordsplash with the word “asexual reproduction.” See what ideas the
students think of.
 Formative Assessment
o Describe what happens to the nucleus when given diagrams, models or
sketches of the different stages of mitosis.
