Cells

In this lesson, we will be exploring the fundamental unit of life, the cell. We will start by discussing the two main types of cells, prokaryotic and eukaryotic, and their differences. We will then delve into the cell membraneA thin, partially permeable barrier surrounding the cell that controls movement of substances in and out. and its functions, including the movement of materials across the membrane. After that, we will explore the cell wallA rigid outer layer that strengthens and supports the cell; made of cellulose in plants and peptidoglycan in bacteria. and its role in providing structural support and protection. We will also discuss the cytoskeleton and its role in maintaining the shape and movement of the cell. Lastly, we will delve into the different cell organelles and their functions, including the mitochondriaAn organelle where aerobic respiration occurs and energy is released., the endoplasmic reticulum, and the ribosomes.
