Pre-AP Grade-Level HW due Friday STAAR Test next Wednesday Vocabulary Essential Question 8th Grade Science Today we will Monday, April 15, 2013 7.12 (C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms; 7.12 (D)differentiate between structure and function in plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole; 7.12 (F)recognize that according to cell theory all organisms are composed of cells and cells carry on similar functions such as extracting energy from food to sustain life. Two Classifications* of Cells
Prokaryotic Cells 1st form of life Have NO nucleus DNA is free (called the nucleloid) ONLY form Unicellular organisms (one-celled) Example: Bacteria (e. coli, staph, salmonella) Eukaryotic Cells Evolved from prokaryotes Have a nucleus with bundled DNA Can form unicellular or multi-cellular organisms. Example: Amoebas, plants animals, fungi, protists *Note: There many TYPES of cells (skin, muscle, hair, sex, etc.,); these are the two categories that ALL cells fall under! It is the DNA within cells that controls what type of cell they will be. Cell Organelles Organelle & Function
*Cell Membrane: Outer cell lining for protection *Cytoplasm: Jelly-like liquid that organelles float in *Nucleus: Control center that contains organisms DNA *DNA: The hereditary material of organisms *Vacuoles: Store nutrients and waste *Mitochondria: Jelly-bean shaped producers of energy (ATP) for cell Plant Organelles PLANT-SPECIFIC organelles: *Cell Wall: Gives plant cells shape and structure (rigidity), made of cellulose *Chloroplast: Site where photosynthesis in plant cells occurs *Large central vacuole: Stores waste and water EVALUATE: What are some similarities between plant and animal cells? What do you notice about the vacuole of the plant cell? Why do you think plants evolved to have cell walls and animals did not? Parts of a Cell 8th Grade Science Monday, April 15, 2013 A cell is like a 8th Grade Science Monday, April 15, 2013 Draw and label an analogy of the cell to something you are familiar with. Possibilities: a school, an airport, a factory, a mall, the solar system, etc. Example: In a grocery store, the sliding doors are like the cell membrane because it decides what goes in and out of the store. The shelves are like the vacuoles because they store materials. The workers are like the mitochondria because they are the energy of the cell, and the store manager is like the nucleus because they tell the store and the people in it what to do.
