Unit 4

NC Essential Standards:

Bio.2.1.1 Analyze the flow of energy and cycling of matter (such as water, carbon, nitrogen and oxygen) through ecosystems relating the significance of each to maintaining the health and sustainability of an ecosystem. Deconstruct the carbon cycle as it relates to photosynthesis, cellular respiration, decomposition and climate change. Bio.3.4.1 Summarize the hypothesized early atmosphere and experiments that suggest how the first “cells” may have evolved and how early conditions affected the type of organism that developed (first anaerobic and prokaryotic, then photosynthetic, then eukaryotic, then multicellular). Bio.4.2.1 Analyze photosynthesis and cellular respiration in terms of how energy is stored, released, and transferred within and between these systems. Analyze overall reactions including reactants and products for photosynthesis and cellular respiration and factors which affect their rates (amounts of reactants, temperature, pH, light, etc.). Compare these processes with regard to efficiency of ATP formation, the types of organisms using these processes, and the organelles involved. (Anaerobic respiration should include lactic acid and alcoholic fermentation.) Note: (1) Instruction should include the comparison of anaerobic and aerobic organisms. (2) Glycolysis, Kreb’s Cycle, and Electron Transport Chain are not addressed. 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.Identify these cell organelles in diagrams of plant and animal cells. (middle school review) Explain how the structure of the organelle determines it function. (Example: folded inner membrane in mitochondria increases surface area for energy production during aerobic cellular respiration). Summarize how these organelles interact to carry out functions such as energy production and use, transport of molecules, disposal of waste, and synthesis of new molecules. (Example: DNA codes for proteins which are assembled by the ribosomes and used as enzymes for energy production at the mitochondria).

Important Dates:

Friday 10/19: Weekly Quiz

Monday 10/22: Cellular Respiration

Tuesday 10/23: Wrap up cellular respiration and complete pig dissection.

Wednesday 10/24: Frog Dissection

Thursday 10/25: Frog Dissection Wrap-up (Submit frog dissection packet as a group, you will have a quiz the next day - Friday)

Friday 10/26: Study Guide Due (Classwork Grade)

Monday 10/29: Unit 4 Test (tentative date)

This online lab looks at the impact that various factors have on photosynthesis. The factors that you will investigate include: color of light, light intensity, amount of carbon dioxide, and temperature.

Lab 1: The effect of color of light on various plants.

Lab 2: The effect of light intensity, amount of carbon dioxide and temperature on photosynthesis.

This is the lab that we will conduct about microscopes. You will be working in a team of two or three to complete the assignment. You will write your answers in your notebook.

final_lab_packet_version - plants

In this lab the students completed a flower dissection. This is the second part of the photosynthesis lab grade. The first part of the grade was the in class pre-lab questions that they needed to answer.

Agenda: 10/23

1) Fill out Cellular Respiration versus Photosynthesis Data Table

2) Virtual Pig Dissection with ODTE chart

Unit 3 - Photosynthesis & Cell Respiration

This is the presentation that we took notes on that went over cellular respiration and photosynthesis.

Photosynthesis and Cellular Respiration Notes

This is your study guide for this unit. You will need to print it out, fill it out by hand, take a picture of it and turn it in on the remind app.
