“In CQ, if they ask about 'Cell' – always draw a diagram and label at least 6 organelles. For 'Tissue' questions – mention location and function with real-life examples (e.g., Blood connects the whole body).” ssc biology chapter 2 hand note exclusive

  • Structure: Contains two cylindrical structures called centrioles.
  • Function: Helps in cell division (spindle formation). Found in animal cells; absent in higher plant cells.

Often called the "brain" of the cell; it contains chromatin which condenses into chromosomes during division. Cell Wall: Nervous Tissue: Conducts nerve impulses

Covers body surfaces and lines organs (Squamous, Columnar, Cuboidal). Connective: Connects and supports (Blood, Bone, Cartilage). Voluntary (Skeletal): Striped, under our control. Involuntary (Smooth): Unstriped, automatic (e.g., stomach). Found only in the heart; rhythmic and tireless. Transmits impulses via Quick Revision Tips for Exams:

  • Chloroplast: Contains chlorophyll; site of Photosynthesis. Double membrane structure with stacks called Grana.
  • Chromoplast: Imparts color (yellow, orange) to fruits/flowers.
  • Leucoplast: Colorless; stores starch, oil, or protein.
  • Day 1: Copy the cell diagrams & organelle table into a dedicated notebook (use colorful pens).
  • Day 2: Practice the Mitosis vs. Meiosis table and the tissue classification flowchart.
  • Day 3: Try to answer the FAQ questions without looking at the notes. Circle what you missed.
