  Cilia vs Flagella: Easy NEET Biology Notes with Diagram & Mind Map  Structure of cilia and flagella showing the 9+2 microtubule arrangement and basal body in a eukaryotic cell. - Dr. Sanjay Kumar Pawar  Cilia and Flagella – Basic Idea Cilia and flagella are hair-like structures present on the surface of the cell. They are extensions of the cell membrane . Cilia Cilia are short and numerous hair-like structures . They move in a coordinated, oar-like motion (like rowing a boat). Function: Help in movement of the cell (e.g., Paramecium). Or move fluid/particles around the cell (e.g., in respiratory tract). Flagella Flagella are long, whip-like structures . Usually present in fewer numbers (1 or 2 per cell) . Function: Responsible for movement of the whole cell (e.g., sperm cell). Difference between Prokaryotic and Eukaryotic Flagella Prokaryotic flagella (bacteria) : Structurally different from eukaryotic flagella. Eukaryotic fla...

 Endomembrane System NEET Notes: ER, Golgi Apparatus & Functions (Class 11) Endomembrane System  Endomembrane System in a Eukaryotic Cell: ER and Golgi working together for protein processing and transport. - Dr.Sanjaykumar pawar Endomembrane System Definition The endomembrane system is a group of cell organelles that work together in a coordinated way. These organelles help in the synthesis, modification, packaging, transport, and digestion of materials inside the cell. Components of Endomembrane System Endoplasmic Reticulum (ER) Golgi Apparatus (Golgi Complex) Lysosomes Vacuoles Important NEET Point These organelles are considered together because their functions are interconnected. Mitochondria, chloroplasts, and peroxisomes are NOT part of the endomembrane system because their functions are independent and not coordinated with the above organelles. 1. Endoplasmic Reticulum (ER) Discovery and Structure Under an electron microscope, ER appears as...

  Cell Theory Explained: Schleiden, Schwann and Virchow Notes for NEET Cell Theory and Overview of Cell showing plant cell, animal cell, nucleus, cytoplasm and membrane-bound organelles. Cell Theory & Overview of Cell (NEET Notes for Beginners) 1. Development of Cell Theory 🧑‍🔬 Matthias Schleiden (1838) German botanist. Studied plant tissues. Concluded that all plants are made up of cells . 🧑‍🔬 Theodor Schwann (1839) German zoologist. Studied animal cells. Observed a thin outer boundary in animal cells, now called the plasma membrane (cell membrane) . Found that cell wall is present only in plant cells . Concluded that animals and plants are composed of cells and cell products . 📖 Cell Theory by Schleiden and Schwann They proposed that: All living organisms are made up of cells. Cells are the basic structural units of life. 🧑‍🔬 Rudolf Virchow (1855) Explained how new cells are formed. Proposed: "Omnis Cellula e Cellula" → All cells arise...
