Agenda for Wednesday, December 9, While You Are Waiting - #3 2.Checking and going over homework 3.Video clip 4.Notes: Organelles that Work Together in the Business of Life and Cellular Boundaries 5.Homework: Page 21

While You Are Waiting 1.Why are water molecules considered polar molecules? 2.What is the difference between a monomer and a polymer? 3.How do enzymes help chemical reactions? They share electrons unevenly between the oxygen and hydrogen causing a positive pole and a negative pole A monomer is one part of a polymer They speed up chemical reactions

Content Objective: I will be able to compare cellular structures and their functions in eukaryotic cells

Organelles that work together in the business of life and Cellular boundaries

Eukaryotic cells can be divided into two major parts: _________ and _________ These two parts of the cell work together in the business of life Cytoplasm is the gel-like fluid portion of the cell outside of the nucleus In our drawings, the blue background represents the cytoplasm the nucleus the cytoplasm

What is the role of the nucleus? The nucleus contains nearly all the cell’s DNA and with it, the coded instructions for making proteins and other important molecules It will control most cell processes Prokaryotic cells do not have nuclei, but they do have DNA which has the same role

Nucleus nucleolus ribosomes nuclear membrane chromosome containing the cell’s DNA- only seen when the cell is dividing otherwise DNA is coiled around proteins in a structure called chromatin

Nucleus nucleolus ribosomes nuclear membrane nuclear pore chromosome containing the cell’s DNA- only seen when the cell is dividing otherwise DNA is coiled around proteins in a structure called chromatin
