Organelles of the Cell; Movement of Materials Into and Out of the Cell Packets #11 & 12 Chapter #3 Wednesday, November 21, 2018

Introduction Organelles are specific structures, found within cells, with specific functions. This packet investigates the different types of organelles and their functions. Wednesday, November 21, 2018

Cell Structure & Function ORGANELLES OF THE CELL 11/21/2018

Inside the Nucleus 11/21/2018

Cell Structure and Function Nucleus Nucleus Structure Contains a eukaryotic cell’s genetic library DNA Location where DNA is replication Location where RNA is produced Nuclear Envelope Surrounds the nucleus Contains nuclear pores Allow things in and out of the nucleus Wednesday, November 21, 2018

Cell Structure and Function Inside the Nucleus Chromatin The complex of DNA and histome proteins which make up chromosomes in eukaryotic cells Chromosomes Long threadlike association of genes composed of chromatin and found inside the nucleus of the cell Nucleolus The region of the eukaryotic nucleus that is engaged in ribosome synthesis Wednesday, November 21, 2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm Cell Structure and Function 11/21/2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm Rough Endoplasmic Reticulum Produces & transports proteins Smooth Endoplasmic Reticulum Produces & transports lipids Ribosomes Made up of RNA & proteins Aids in making proteins at the Rough ER Wednesday, November 21, 2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm Golgi Apparatus Stack of membranous sacs Packages and distributes lipids and proteins that form in the ER Lysosome Contains digestive enzymes that degrades the cell and other malfunctioning organelles Wednesday, November 21, 2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm Peroxisome Contains enzymes that carry out redox reactions and is key in detoxification of drunks Mitochondria Location for energy production ATP Wednesday, November 21, 2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm Cells are composed of filaments Microtubules Microfilaments Intermediate filaments Wednesday, November 21, 2018

Cell Structure and Function Outside the Nucleus Inside the Cytoplasm {Plant Cells Only} Chloroplasts In plant cells Used in photosynthesis Wednesday, November 21, 2018

The Plasma Membrane 11/21/2018

Components of the Plasma Membrane The plasma membrane is composed of phospholipids. Permits materials to enter and leave the cell. Diffusion Osmosis Wednesday, November 21, 2018

Diffusion I Regular Diffusion High to low Facilitated Diffusion Protein Active Transport Low to High ATP 11/21/2018

Diffusion V Osmosis Osmosis Special type of diffusion The movement of a liquid solvent from an area of high concentration to an area of low concentration through a semi-permeable membrane. The membrane does not allow solutes to pass through. 11/21/2018

Osmosis Hypertonic vs. Hypotonic Hypertonic Solution High concentration of solute Low concentration of solvent Solvent wants to enter Hypotonic Solution Low concentration of solute High concentration of solvent Solvent wants to leave 11/21/2018
