The lecturer starts by emphasizing that the mitotic process is a separate mechanism to cytokinesis - the cytoplasm splitting to become 2 cells. The video continues explaining the stages of mitosis in great detail. Each stage is diagrammed and the relevant structures are labeled and explained. Your students will find this to be a valuable supplemental study tool.
It is fascinating to learn about apoptosis and the fact that cells are able to destroy themselves without any external influence. Sal creates interest in the huge number of cells and the complexity of the human body. The likelihood of a mutation causing a problem is small, and that mutation would have to be within the genes controlling self-destruction and replication. The lecture continues with details of tumor growth and the differences between malignant, benign, invasive, and metastases.
High schoolers are able to identify the different stages of mitosis and what occurs in each stage. They can identify the importance of the cell cycle control in maintaining homeostasis. Students are able to match the correct stage of mitosis with actual microscope images of the cell cycle.
High schoolers are able to see onion root cells undergoing mitosis underneath a light microscope and determine the phase of mitosis the cells are in. They draw a sketch of the mitotic cells. Students explore the phases of mitosis and the cell cycle. They explore why cells undergo mitosis and how uncontrolled cell division leads to cancer.
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a graph. The procedure is clear and the questions are relevant, but the appearance of the lab sheet is quite boring. If this is not of importance to you, then this is a terrific resource for your biology class when learning about osmosis and the cell membrane.
Like a fresh canvas, stem cells can turn into almost anything. In a comprehensive lesson, high school biologists use clay to build a 3-D model of cell division and the processes that occur during the first 14 days of development. Also included is a detailed graphic organizer for taking notes about the important concepts and vocabulary related to stem cells. The procedure is very clear and easy to follow; your pupils will enjoy getting their hands dirty while learning about how they all came to be.
Stimulate critical thinking about the proteins that are active within eukaryotic cells. Biology masters explain where DNA is found, its relationship to RNA, how the endoplasmic reticulum and Golgi bodies interact, and more. They also diagram the process of protein formation. After answering 15 questions, learners also review the foundational concepts of cell structure and theory. This makes a practical review assignment during your cell structure and function unit.
Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated and deoxygenated blood throughout the system, and through arteries and veins.
Students use Internet activities and videos to understand the types of cells, their membranes, and the way that they reproduce. In this cellular biology lesson, students use the Internet to view videos and complete activities. They investigate single-celled organisms, the cell membrane, and mitosis.
Students distinguish the differences between Prokaryotic and Eukaryotic cells. Using microscopes, they examine a variety of plant and animal cells. Working in groups, they draw and label plant and animal cells and show the mathematical formula used to determine the cells' magnification.
Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for students who are familiar with the basic principles of plant cell structure, tissue culture, sterile technique, and cell transformation (bacterial infection, plasmid vectors, marker genes, selection medium, and enzyme activity assays).
