1. Basic Cell Structure and Organelles

Key Concepts & Definitions

  • Cell : The basic structural and functional unit of the body, consisting of a cell membrane, cytoplasm, nucleus, and major organelles.

★ Must-know

  • The major cell organelles are:
    • mitochondria
    • ribosomes
    • endoplasmic reticulum
    • Golgi apparatus
    • lysosomes

Further detail

  • The nucleus is a major cell component, while the cytoplasm occupies the region between the nucleus and cell membrane.

2. Cell Membrane and Its Proteins

Key Concepts & Definitions

  • Cell Membrane : A very thin, flexible structure that encloses each cell, supports its internal structure, and selectively controls the entry and exit of substances.

📌 Integral proteins are embedded within the lipid bilayer, whereas peripheral proteins are attached to the membrane surface without penetrating it.
