BIOLOGY LESSON PLAN

**Title: Lesson Plan for 9th Grade Cell Biology **
===**Objective: **Upon completion of this lesson, the student will to tell the differences between plant and animal cells and describe the components of each type of cell and be able to determine the differences between pland cells and animal cells. The student will also receive information on origins of information. The student will observe cells under a microscope. All students will receive a copy of the lesson and diagrams that I will use as a PowerPoint presentation if equipment is available, so no one will feel left out. All students will be encouraged to make the handout part of their notes. Questions will be answered to insure complete understanding as this is an item for the NJ state Biology Proficiency Test. ===

===**Materials needed: **Biology Department Microscopes, 1 microscope per 4 students ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Pre-assessment: ** I will first ask the class if there are any students that need the class diagrams in another subject. <span style="font-family: Arial,sans-serif; font-size: 12pt;">Oral quiz to determine levels of critical thinking. Teacher introduces himself and describes cultural and family background. Students individually introduce themselves and describe their cultural background. Encourage students to bring in photos, cultural artifacts, bring in clothing, etc to show off your heritage. ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Critical thinking: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">Questions to be used to assess levels of understanding: ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Knowledge: ** Let us consider becoming a Biologist and doing research to answer the following questions: What do Biologists do? (Investigate). What role do they play in science? (Look for answers to problems.). Are there other fields where knowing Biology could be important? (Yes.). Do Biologists have any impact on medicine? (Very much, research, new drugs, new illnesses, etc.). Who can be a Biologist? (Anyone.). Do they have to go to college? (Yes). Where do they work? (In a laboratory, around animals, in a crime laboratory, etc.). <span style="font-family: Arial,sans-serif; font-size: 12pt;">Who is the father of Biology? (Aristotle {384 BC to 322 BC} – Greek philosopher - investigated the differences between animal and plant cells). What is a cell? (Smallest part of plants or animals). Why are they important? (Everything living is made of cells.). Are plants and animal cells the same? (Yes.). How are they different? (they are constructed differently.). What do they do? (reproduce so the plant or animal grow.) Are they are alive? (Yes.) What purpose do they serve? (They give the plant or animal structure.). What is a microscope? (A tool.). Who invented the microscope? (Galileo, Anthony Leeuwenhoek of Holland, <span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">Robert Hooke, an Englishman (who is sometimes called the “English Father of Microscopy”, all experimented with lenses and made various improvements to make microscopes the fine optical devices they are today). ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Comprehension: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">Do you understand why there are differences between animal and plant cells? Why do plant cells need a cell wall and animal cells do not? Why are plants green? What would happen if animal cells had cell walls? Name some different types of animal cells and their functions? Can you see cells with the naked eye? Can you see cells with a telescope? ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Application: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">Draw a multi-celled plant and describe what it needs to grow? Describe the functions of plant and animal cells. Describe the different types of cells in an animal’s body and describe their use. What do plants need to grow? Describe how a microscope works. Demonstrate the proper use of a microscope. ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Analysis: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">Explain how the functional differences between plants cells and animal cells are necessary for the plant or the animal. Can plant and animal cells be mixed into one organism and why? ===

===**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Synthesis: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">How do think this information in the future? Is this the end of the my need to study cellular biology? How will studying animal and plant cells help you understand the cycles of life? What part do cells plan in our life functions? ===

**<span style="font-family: Arial,sans-serif; font-size: 12pt;">Evaluation: **<span style="font-family: Arial,sans-serif; font-size: 12pt;">Written exam upon completion of lesson and review.

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">cell membrane __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - the thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">centrosome __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - (also called the "microtubule organizing center") a small body located near the nucleus - it has a dense center and radiating tubules. The centrosomes is where microtubules are made. During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">cytoplasm __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - the jellylike material outside the cell nucleus in which the organelles are located. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">Golgi body __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - (also called the Golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for "export" from the cell. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">lysosome __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - (also called cell vesicles) round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">mitochondrion __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">nuclear membrane __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - the membrane that surrounds the nucleus. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">nucleolus __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - an organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">nucleus __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">ribosome __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis. ===

===**__<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;">rough endoplasmic reticulum __**<span style="background-color: white; font-family: Arial,sans-serif; font-size: 12pt;"> - (rough ER) a vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transports materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane). ===

===<span style="font-family: Arial,sans-serif; font-size: 12pt;">**__smooth endoplasmic reticulum__** - (smooth ER) a vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell's cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body, lysosomes, and membranes. ===

===<span style="font-family: Arial,sans-serif; font-size: 12pt;">**__vacuole__** - fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell. ===
