Wake-up 1.What did you notice about the “e” when viewed under the microscope? Draw it. 2.What do you notice when you move the slide to the right while viewing through the eyepiece?
Wake-up 1.Identify the following structures: A, B, C, D 2.Explain the function of D. A D C B
Eukaryotic Cells - Honors Christopherson
Recall: Robert Hooke examined cork and named the tiny boxes a “cell”
What is a cell? The cell is the basic unit of life within living organisms
Where is a cell in you? Organism That’s you
Where is a cell in you? Organ systems
Where is a cell in you? Organs
Where is a cell in you? Tissue
Where is a cell in you? Cell
What does this have to do with Biology???
Inside the cell are ORGANELLES(structures inside the cell that perform specific function)
Eukaryotic Cell Definition Complex cells that have “membrane- bound” organelles. “Membrane-bound” means that they have an outer layer.
Two main types of Eukaryotic Cells 1. Animal Cell 2. Plant Cell
What are some organelles in animal and plant cells?
Nucleus Location: Large circle typically in the middle of the cell Function: Control center of the cell; location of DNA
Nucleolus Location: Small circle inside of the nucleus Function: Makes ribosomes
Ribosomes Location: Small dots all over the cell Function: Location of protein synthesis; where proteins are made
Rough Endoplasmic Reticulum Location: On the nucleus
Rough Endoplasmic Reticulum Function: Perform the synthesis and transport of proteins. Made up of a system of tubes, vesicles, and covered with ribosomes
Golgi apparatus Location: Within cell; stack of tubes
Golgi apparatus Function: Processes and packages proteins and lipids that are made; Similar to a post office
Wake-up 1.How can you tell the difference between a nucleolus and nucleus? 2.What three organelles function that relates to proteins? What is their difference?
Mitochondria Function: Breaks down sugar into ATP (usable form of energy); Powerhouse of the cell Location: Throughout the cell
Chloroplast Location: Green “beans” throughout a plant cell Function: Location of photosynthesis; process by which plants make food
Vacuole Location: Throughout an animal cell; makes up the majority of a plant cell Function: Stores water, food, waste, etc.
Lysosome Location: Throughout a cell Function: Gets rid of waste within the cell
Lysosome
Smooth Endoplasmic Reticulum Location: On the nucleus and near the Rough ER
Smooth Endoplasmic Reticulum Function: Produces lipids such as steroids, phospholipids
Location: Outer layer of the cell Function: Control what comes in and out of the cell; gatekeeper Cell/Plasma Membrane
Location: Outermost layer in plant cellsFunction: Provide structure and support Cell Wall
Cytoplasm Location: Inside of the cell Function: Provides a liquid environment for the various dissolved substances and some structure
Location: Throughout an animal cell Function: Provide structure and support Cytoskeleton
Chloroplast Mitochondria Cell Membrane Vacuole Cell Wall Ribosomes Nucleus Cytoplasm Nucleolus Lysosome
What are the difference between an animal and plant cell?
