Student of the Week Textbook pages 58-59 Numbers 2 and 4 Chapter 7: Cell Structure and
Function What are cells??? Cells are the basic units of life. Cell Theory
All living things are made up of cells Cells are the basic units of structure and function in living things New cells are produced from existing
cells Organelles Eukaryotic cells have specialized substructures, called organelles, carry out the essential functions of life. little organs
Chart, flashcards, or notes your choice! Eukaryotic Cells Animals and Plants Organelles
The cytoplasm is the semi-fluid material that contains the organelles Organelles The cell membrane is the thin flexible barrier surrounding a cell
Lipid bilayer Regulates what enters and leaves the cell Selectively permeable membrane Protects and supports the cell Organelles The nucleus contains the chromosomes which are composed of
DNA (deoxyribonucleic acid, a chemical compound that stores and transmits genetic information) and functions as the genetic control center of the cell Organelles A chromosome is a structure in the nucleus of a cell consisting
essentially of one long thread of DNA that is tightly coiled. Organelles The cytoskeleton is a network of fibrous proteins that helps the cell with maintaining shape, support, and movement.
Organelles Endoplasmic reticulum (ER) is a complex, extensive network that transports materials throughout the inside of a cell. Rough ER has ribosomes
attached to the surface. Smooth ER has no ribosomes Organelles Ribosomes are the sites of protein synthesis; some are located on the
ER, others are found in the cytoplasm. Organelles The Golgi complex/ apparatus modifies, collects, packages, and distributes proteins and other materials to be used within or outside
the cell. Organelles Lysosomes break down lipids, carbohydrates, and proteins into small molecules that can be used by the cell.
Organelles Vacuoles store materials like water, salts, proteins, and carbohydrates. Organelles Vesicles are smaller structures that
store and move materials between cell organelles, as well as to and from the cell surface. Organelles Mitochondria supply the energy for the cell Converts chemical energy stored in food
into usable energy for the cell POGIL Activity Directions Group deliverables: on poster paper Create a chart that matches the part of a
factory to an organelle (this is an analogy!) Use the handout BEFORE you draw on your poster Labeled and colored cell drawing from handout Flowchart (question 9) See Figure 7.11 on Pages 200-201 of your
textbook Individual deliverables: on handout Questions 1-18 Proteins Cellular processes are carried out by
molecules. Proteins carry out most of the work of cells to perform the essential functions of life. One of the major functions of the cell is the production of proteins. The genetic information in DNA provides instructions for assembling protein molecules. In eukaryotic cells the nucleus, ribosomes, endoplasmic reticulum, vesicles, and the Golgi apparatus interact to produce, modify and transport proteins.
