  • Microvilli

    Microvilli are membrane specializations that increase the surface area of a cell for absorption.

  • Cilia

    Cilia are hair-like projections on the cell surface that help move substances across the cell membrane.

  • Flagella

    Flagella are long, whip-like structures that enable cell movement.

  • Secondary active transport

    Secondary active transport uses the energy from an ion gradient created by primary active transport to move other substances against their gradient.

  • Vesicular transport

    Vesicular transport moves large molecules or particles across the membrane using vesicles, including endocytosis and exocytosis.

  • Phases of protein synthesis

    Protein synthesis includes transcription in the nucleus and translation in the cytoplasm involving ribosomes.

  • Transcription

    Transcription is the process of copying DNA into mRNA inside the nucleus.

  • Translation

    Translation is the process where ribosomes read mRNA to assemble amino acids into a protein in the cytoplasm.

  • Role of ribosomes in protein synthesis

    Ribosomes facilitate the assembly of amino acids into proteins during translation.

  • Endocytosis

    Endocytosis is a vesicular transport process where the cell engulfs substances by forming vesicles from the plasma membrane.

  • Exocytosis

    Exocytosis is the process of vesicles fusing with the plasma membrane to release contents outside the cell.

  • Cell death

    Cell death refers to the process by which cells cease to function and are removed, including apoptosis and necrosis.
