Grade Level: 10th Grade
Unit Title: Unit 1- Structures and Functions of Living Organisms |Timeframe Needed for Completion: 3 weeks (on a 90 min per day block schedule)
Grading Period: 1st Nine Weeks | |
|Big Idea/Theme: Structures and Functions of Living Organisms |
| |
|Understandings: This unit is focused on the cell as the basic component of structure and function in living things. In particular, this unit focused on basic biochemistry and cell processes. Students |
|will learn about cells and many of the molecules that are involved in cell function. Specifically, students will gain an understanding of: |
| |
|role of inquiry in investigating cells |
|basic macromolecules found in living things, the structures of those molecules and their function in living systems. |
|the function of those macromolecules within the context of cell structure |
|the functions of various cell organelles |
|the maintenance of homeostasis within a cell |
|the replication of DNA in order to prepare for cell division |
|sexual and asexual reproduction at the cellular level |
|how DNA directs the production of proteins within a cell |
|the effects of mutations on protein production |
|the relationship of gene regulation, cell specialization, and cell communication |
|Eukaryotic and Prokaryotic Cells and their general structures |
|Cell cycle and its phases |
|Unicellular Organisms and their adaptations for survival |
| |
| |
|Essential Questions: |Curriculum Goals/Objectives (to be assessed at the end of the unit/quarter) |
|Imagine you went back in time to 1776. How would you explain | |
|to people what a cell was? |New clarifying objectives for the 2009 Curriculum have been underlined. |
|If you were a stem cell and could specialize into any type of | |
|cell, what type would you turn into and why? |Bio.1.1 Understand the relationship between the structures and functions of cells and their organelles. |
| |Bio.1.1.1 Summarize the structure and function of organelles in eukaryotic cells (including: the nucleus, plasma membrane, |
| |cell wall, mitochondria, vacuoles, chloroplasts, and ribosomes) and ways that these organelles interact with each |
| |other to perform the function of the cell. |
| |Bio.1.1.2 Compare prokaryotic and eukaryotic cells in terms of their general structures (plasma membrane and genetic material) and degree of |
| |complexity. |
| |Bio.1.1.3 Explain how instructions in DNA lead to cell differentiation and result in cells specialized to perform specific functions in |
| |multicellular organisms. |
| | |
| |Bio.1.2 Analyze the cell as a living system. |
| |Bio.1.2.1 Explain how homeostasis is maintained in the cell and within an organism in various environments (including: |
| |temperature and pH). |
| |Bio.1.2.2 Analyze how cells grow and reproduce in terms of interphase, mitosis and cytokinesis. |
| |Bio.1.2.3 Explain how specific cell adaptations help cells survive in particular environments (focus on unicellular organisms). |
| | |
| |Bio.3.1 Explain how traits are determined by the structure and function of DNA. |
| |Bio.3.1.1 Explain the double-stranded, complementary nature of DNA as related to its function in the cell. |
| |Bio.3.1.2 Explain how DNA and RNA code for proteins and determine traits. |
| |Bio.3.1.3 Explain how mutations in DNA that result from interactions with the environment (i.e. radiation and chemicals) or new combinations in |
| |existing genes lead to changes in function and phenotype. |
| | |
| |Bio.3.2 Understand how the environment, and/or the interaction of alleles, influences the expression of genetic traits. |
| |Bio.3.2.1 Explain the role of meiosis in sexual reproduction and genetic variation. |
| | |
| |Bio.4.1 Understand how biological molecules are essential to the survival of living organisms |
| |Bio.4.1.1 Compare the structures and functions of the major biological molecules (carbohydrates, proteins, lipids, and nucleic acids) as related|
| |to the survival of living organisms. |
| |Bio.4.1.2 Summarize the relationship among DNA, proteins and amino acids in carrying out the work of cells and how this is similar in all |
| |organisms. |
