Ssc Biology Chapter 2 Hand Note Exclusive Repack

SSC Biology Chapter 2: Cells and Tissues of Organisms

For , an "exclusive" hand note should prioritize the structural differences between plant and animal components and the specialized functions of various tissues. 1. Cell Structure & Organelles

• Occurrence: Somatic cells (body cells).
• Process: One cell divides into two identical daughter cells.
• Chromosome Number: Remains the same (Diploid or 2n).
• Significance: Growth, tissue repair, asexual reproduction.

Epithelial

| Tissue | Function | Example Location | | :--- | :--- | :--- | | | Protection, secretion, absorption | Skin, inner lining of mouth | | Connective | Connects & supports organs | Blood, Bone, Cartilage, Ligament | | Muscular | Movement & locomotion | Heart (cardiac), Arms (skeletal), Stomach (smooth) | | Nervous | Conducts nerve impulses | Brain, Spinal cord, Nerves | ssc biology chapter 2 hand note exclusive

• Occurs in Somatic cells (Body cells).
• Result: One parent cell produces two identical daughter cells with the same chromosome number (Diploid, 2n).
• Significance: Growth, repair, and asexual reproduction.

Discovery:

The cell is the basic structural and functional unit of life. First seen by Robert Hooke in 1665. Prokaryotic vs. Eukaryotic: SSC Biology Chapter 2: Cells and Tissues of
