Videos and experiments that are suitable for Biology.
Here we look at the major phases of meiosis, how cells are selectively permeable with the help of their cell membrane, Phases of Meiosis and Cell Membranes.
Phases of Meiosis
This video explains the major phases of meiosis including: interphase, prophase I, metaphase I, anaphase I, telophase I, cytokinesis, interphase II, metaphase II, anaphase II, and telophase II. It explains how variation is created in the next generation through meiosis and sexual reproduction.
The Cell Membrane
This video gives you a brief introduction to the cell membrane. It starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. It gives an overview of the fluid mosaic model inside cells. It also discusses the movement of material across a membrane and the role of proteins in movement and function.
This video explains how cells are selectively permeable with the help of their cell membrane. The main constituents of the cell membrane, including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins are included. The fluid mosaic model is also illustrated. The cell wall in plants, bacteria, and fungi is also discussed.
