2.1 Macomolecules

​Unit 2-Cells at Work

Do NOW:

During the winter months, many mammals undergo periods of physiological dormancy called torpor (/ˈtôrpər/) and hibernation. Some animals, like bears, are able to do daily torpor while other animals undergo a prolonged hibernation. Predict how this might work. Connect this to concepts we have previously discussed in class. 

SWBAT support ideas in discussions about Macromolecules using data, textual evidence, or examples (ex: To demonstrate ____, according to ____)

Language

SWBAT differentiate between the major macromolecules based on their structure and/or function and explain their roles in cells.

​Standard

Objectives

Open Ended

To get ready for hibernation, animals will eat more than usual during the fall to store up body fat. Generate a prediction as to why this might occur. 

Open Ended

1. Why do autotrophs go through photosynthesis?

1. Why do we eat food?

ORGANIC MOLECULE

In Biology, we are referring to carbon-based molecules that make up living organisms.

1. Life cannot exist without the four main organic molecule. Identify the four. 

2. Organic molecules are made up of six major elements. Identify the six.

2.1 Macromolecules Exit Ticket

Cellulose is important for the structure of cell walls of plant cells (Figure 1). It is one most common polymers on earth. The structure of cellulose is shown in Figure 2.

Criteria for Success:

Determination of the type and function of organic molecules includes:

• Accurate identification as a monomer or polymer

• Accurate identification of the macromolecule

• Accurate description of function of the molecule for structure or energetics of the cell
