Be ready to explain why the Mitochondria is called the "Powerhouse" or why the Nucleus is the "Brain" of the cell.
Make sure to draw and label diagrams of:
Dead, thick-walled cells heavily lignified. Divided into fibers and sclereids. Provides structural rigidity and mechanical support. Complex Permanent Tissues ssc biology chapter 2 hand note exclusive
The "Powerhouse of the cell." Site of cellular respiration and ATP production. Ribosome (রাইবোজোম): Protein factory.
Long, tube-like dead structures placed end-to-end with open perforations. Xylem Parenchyma: Living cells that store food. Be ready to explain why the Mitochondria is
Sclerenchymatous dead cells providing mechanical support. 2. Phloem (Food Conduction)
Present in animal cells (for division); usually absent in higher plants. 2. Key Organelles and Their Functions Provides structural rigidity and mechanical support
Animal tissues are categorized into four fundamental types based on structure, location, and functional differentiation. 1. Epithelial Tissue
