Each part of the cell performs a specific function that is vital for the cell's survival. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Students should be able to describe the major components of a cell, including the cell membrane, cytoplasm, nucleus, ribosome, endoplasmic reticulum etc.On this page you can read or download gina wilson all things algebra 2012 unit 5 systems of equations inequalities homework 1 solving systems by graphing answer.Students use the hands on associated activity to look at the components of cells and their functions. Goals: Students should be able to explain and apply cell theory. Lab activity - observing cells using the light microscope. Introduction to DNA, cell division and mitosis.

Cells are the building blocks of living things. Eliminating most of the answer sheet bubbling that has added to testing time and fatigue.This engineering curriculum aligns to Next Generation Science Standards ( NGSS).2. 43 UNIT 2: Cell Structure and Function. Text book section 1.2, questions on page 28 1, 2, 3, 6, 8: 24-Oct: Karyotype Activity: handout: 28-Oct: Diffusion and Osmosis. DNA, genes and chromosomes: see google classroom for note 2. Engineers use bacteria to break down toxic materials in a process called bioremediation, and they also disable or kill harmful bacteria through disinfection.Lab Activity viewing animal and plant cells: 22-Oct: Complete Lab Activity: lab questions due Thurs Oct 24: 23-Oct: Quiz cells parts and microscopes.

Diffusion across a biological membrane. Sss 6.more than one answer. Cells are extremely small. Microscopes are tools that allow the observation and study of very small objects such as cells.

List examples of how engineers use cells to keep people and the environment safe and healthy.Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.Click to view other curriculum aligned to this Performance ExpectationThis lesson focuses on the following Three Dimensional Learning aspects of NGSS:Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell.Alignment agreement: Thanks for your feedback!Complex and microscopic structures and systems can be visualized, modeled, and used to describe how their function depends on the relationships among its parts, therefore complex natural structures/systems can be analyzed to determine how they function.International Technology and Engineering Educators Association - TechnologyToday, we are going to talk about cells and how important they are. Compare and contrast prokaryotic and eukaryotic cells. Thus, soap is an engineered product that was made for a specific purpose (solving the problem of dirty, contaminated 'things'), but is widely used for a multitude of applications.After this lesson, students should be able to:

Engineers have learned to use bacteria that 'eat' oil as a way to speed up oil spill clean-up. Although we can clean up a lot of the oil, it is usually impossible to clean up all of the oil right away since the spills often cover a large area and spread quickly. Have any of you seen pictures of oil spills? (Note: If available, show students pictures from the Deepwater Horizon oil spill in the Gulf of Mexico in 2010 or the Exxon Valdez oil spill off the coast of Alaska in 1989.) They are very damaging to the environment. Refer to the Sudsy Cells activity to have students engineer their own investigation of bacteria gowth and applications to help prevent those that are unwanted!Not only is it important to have good bacteria living in our bodies, but it is also beneficial to have organisms in the environment that 'eat' pollution. Can anyone think of a way that we might protect ourselves from cells that might make us sick? (Possible examples include: washing your hands and covering your mouth when you cough the sterilization of surgical tools the treatment of drinking water before it comes out of the tap.) Now, can anyone name one way to make sure that helpful bacteria stay alive? (Discuss how doctors recommend that we eat unpasturized yogurt to keep good bacteria in our digestive tract).

While the science behind cells is important to know, the engineering behind cells is fascinating. In order to be alive, a cell must have a metabolism, respond to stimuli and reproduce. Even though the two types of cells are very different, they are both able to eat, breathe, grow and reproduce.Lesson Background and Concepts for TeachersCells are living organisms. Prokaryotes are cells that are found in bacteria, and they do not have organelles. Eukaryotes are the cells that make up our body, and they have many parts called organelles. Today we are going to learn about the two major types of cells: eukaryotes and prokaryotes.

The difference between bacteria and archaea is their type of cell wall: archaea have a thicker cell wall that is very strong and protects it from the heat and chemicals found in harsh environments, and bacteria have a more permeable cell wall that provides less protection from high temperatures or extreme pH, but takes less energy to build. In additon, archaea are found in extreme environments such as hot springs or near volcanoes. Bacteria make up most of the prokaryotes. Even with a minimal number of parts, these cells are able to eat, breathe and reproduce.Two kingdoms of organisms comprise prokaryotes: bacteria and archaea. The major parts of a prokaryotic cell include: cell wall, cell membrane, ribosomes, and a nucleoid (see Vocabulary section).

There are both unicellular and multicellular eukaryotes. The major organelles found in a eukaryotic cell are: cell membrane, cell wall, ribosomes, nucleus, mitochondria, endoplasmic reticulum and lysosomes (see Vocabulary section). Although they sometimes live in colonies, each cell could survive on its own and reproduce without the others.Copyright В© Surveillance, Epidemilogy and End Results (SEER) Program, National Cancer Institute Eukaryotes are complex cells with many organelles.

Protists are single celled motile organisms that can be either photosynthetic or heterotrophic.Some similarities between prokaryotes and eukaryotes exist. Plants, animals and fungi are all multicellular organisms. Fungi digest their food externally and then absorb it through their cell walls. Animals are organisms that lack cell walls, but are capable of locomotion and have a digestive tract. Plants are photosynthetic organisms containing cell walls and specialized reproductive tissue.

Engineers must understand cell structure in order to design strategies to destroy harmful cells so that we can lead healthy lives. Can anyone tell me one difference between the two kinds of cells? (Answer: Prokaryotes do not have a nucleus or other membrane bound organelles while eukaryotes do.) Can anyone name one example of a prokaryote? (Answer: Bacteria that can make us sick or the beneficial bacteria used in bioremediation and in our digestive tract.) Can anyone give an example of a eukaryote? (Possible answers: Plants, animals, mushrooms, algae, not all eukaryotic organisms are multicellular.) The differences and similarities between the two types of cells are important to engineers because they use this information when trying to control cell growth in the environment, which is important to plans, animals and especially humans.
