■■Enduring Understandings
• 1A2: Natural selection acts on phenotypic variations in populations.
• 2A3: Organisms must exchange matter with the environment to grow, reproduce, and
maintain organization.
• 2B1: Cell membranes are selectively permeable due to their structure.
• 2B2: Growth and dynamic homeostasis are maintained by the constant movement of
molecules across membranes.
• 2D1: All biological systems from cells and organisms to populations, communities, and ecosystems are affected by complex biotic and abiotic interactions involving the exchange of matter and free energy.
• 4A4: Organisms exhibit complex properties due to interactions between their
constituent parts.
• 4A6: Interactions among living systems and with their environment result in the movement of matter and energy.
■■Learning Objectives
• I will be able to connect evolutionary changes in a population over time to a
change in the environment (1A2 & SP 7.1).
• I will be able to use calculated surface area-to-volume ratios to predict which
cell(s) might eliminate wastes or procure nutrients faster by diffusion (2A3 & SP 2.2).
• I will be able to justify the selection of data regarding the type of molecules that an animal, plant, or bacterium will take up as necessary building blocks and excrete as
waste products (2A3 & SP 4.1).
• I will be able to represent graphically or model quantitatively the exchange of
molecules between an organism and its environment, and the subsequent use of these molecules to build new molecules that facilitate dynamic homeostasis, growth, and reproduction (2A3 & SP 1.1, SP 1.4).
•I will be able to predict the effects of change in a component(s) of a biological
system on the functionality of an organism(s) (4A4 & SP 6.4).
• I will be able to apply mathematical routines to quantities that describe
interactions among living systems and their environment that result in the movement of matter and energy (4A6 & SP 2.2).
• I will be able to use visual representation to analyze situations or solve problems qualitatively to illustrate how interactions among living systems and with their environment result in the movement of matter and energy (4A6 & SP
1.4).
■■Skills Development
Students will develop the following skills:
• Preparing a stomatal peel using nail polish
• Making a wet mount of leaf epidermal tissue for microscopy
• Calculating leaf surface area and number of stomata/surface area
• Assembling a potometer
• Calculating transpiration rates

Ch. 6 Review
O-Macromolecules- concept map due Friday-
Overview of transport in plants
http://www.bozemanscience.com/plant-nutrition-transport
Getting started (pg. 137): 1-4
Complete Step 1 (pg. 138) A-H
Step 2- stomata imprint: work in two teams of three- investigate the stomata density on the top and bottom surface of a leaf. (make two counts and then switch with the other team for two more counts). Compare density for the following plants:
Fig - (Ficus)
Bromeliad
Philodendron
ern
Gery Oak (Quercus)
Calculating field of view-
Enter average into Excel spreadsheet. Discuss question
Design and conduct your investigation - page 140
