- The cytoskeleton (article) | Khan Academy
The cytoskeleton Microtubules, microfilaments (actin filaments), and intermediate filaments Centrioles, centrosomes, flagella and cilia
- The cytoskeleton (article) | Cytoskeleton | Khan Academy
The cytoskeleton Microtubules, microfilaments (actin filaments), and intermediate filaments Centrioles, centrosomes, flagella and cilia
- Structure of the plasma membrane (article) | Khan Academy
The fluid mosaic model of the plasma membrane Protein, lipid, and carbohydrate components of the membrane
- The endomembrane system (article) | Khan Academy
The endomembrane system (endo - = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus, which we will cover shortly
- Phases of mitosis | Mitosis | Biology (article) | Khan Academy
The great majority of the cell divisions that happen in your body involve mitosis During development and growth, mitosis populates an organism’s body with cells, and throughout an organism’s life, it replaces old, worn-out cells with new ones For single-celled eukaryotes like yeast, mitotic divisions are actually a form of reproduction, adding new individuals to the population
- The extracellular matrix and cell wall (article) | Khan Academy
On the inner side of the membrane, the integrins are linked to the cytoskeleton Integrins anchor the cell to the extracellular matrix In addition, they help it sense its environment They can detect both chemical and mechanical cues from the extracellular matrix and trigger signaling pathways in response 4, 5
- Cell parts and functions (article) | Khan Academy
All cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts
- Cellular organelles and structure (article) | Khan Academy
Cytoskeleton Within the cytoplasm there is network of protein fibers known as the cytoskeleton This structure is responsible for both cell movement and stability The major components of the cytoskeleton are microtubules, intermediate filaments, and microfilaments
- Plasma membrane and cytoplasm (article) | Khan Academy
Similarly, the cytoplasm of a eukaryotic cell consists not only of cytosol—a gel-like substance made up of water, ions, and macromolecules—but also of organelles and the structural proteins that make up the cytoskeleton, or "skeleton of the cell " In this article, we’ll take a closer look at the plasma membrane and cytoplasm
- Cell structure and function | AP®︎ College Biology - Khan Academy
Take your cellular knowledge to the next level! From organelles to membrane transport, this unit covers the facts you need to know about cells - the tiny building blocks of life
