While You Are Waiting 12/8/16 What do you see? What do you think? What do you wonder?
Agenda for Thursday, December 8, 2016 While You Are Waiting - #4 Video Clip - Lysosomes Notes: Organelles that Store, Clean up, and Support Homework: Study the organelles and their functions
Lysosome Video Clip
Content Objective: I will be able to compare cellular structures and their functions in eukaryotic cells
Organelles that Store, Clean up, and Support
Organelles that store, clean up, and support Vacuoles, Vesicles, Lysosomes, and the Cytoskeleton Vacuoles are large saclike structures that store materials like water, salts, proteins, and carbohydrates Plants cells contain a large central vacuole that helps support heavy structures such as leaves Some single celled organisms such as paramecia have contractile vacuoles that help pump out excess water
Paramecium
As compared to vacuoles, vesicles are smaller structures which store and move materials between cell organelles
As compared to vacuoles, vesicles are smaller structures which store and move materials between cell organelles vesicle vesicle
Lysosomes are small organelles filled with enzymes that break down lipids, carbohydrates, and proteins into small molecules that the cell can use They also break down old organelles lysosome
Please remain in your seat until the bell rings
While You Are Waiting 12/9/16 Which organelle is involved in photosynthesis? How might available sunlight, water or temperature affect the rate of photosynthesis? 1 2 3
Agenda for Friday, December 9, 2016 While You Are Waiting - #5 (I am collecting today) Cytoskeleton Video Clip Notes: Organelles that Support Homework: Organelles in Eukaryotic Cells Sheet
Content Objective: I will be able to compare cellular structures and their functions in eukaryotic cells
The cytoskeleton is a network of fibers and tubes that help the cell maintain its shape and allows certain organelles to move as well as certain cells to move cytoskeleton cytoskeleton
The cytoskeleton is a network of fibers and tubes that help the cell maintain its shape and allows certain organelles to move as well as certain cells to move Cytoskeleton consists of microtubules- hollow protein structures Cytoskeleton consists of microfilaments- threadlike structures made of proteins called actin
Microtubules help many cells maintain their shape, form centrioles which aid in cell reproduction, and form cilia and flagella which allow some single celled organisms to move Microfilaments provide a flexible support for some cells and help other cells such as amoebas to move centrioles Cytoskeleton consists of microfilaments- threadlike structures made of proteins called actin
Cilia and Flagella bacteria paramecium flagella
