2. Definition – Structural and functional unit of living organism. (Basic Unit of life). Discover by – Robert Hooke Cell Theory – M.J. Schleiden and J.S. Schewann It is typically microscopic and consists of cytoplasm and a nucleus enclosed in a membrane . Karyokinesis – Division of Nucleus. Cytokinesis – Division of Cytoplasm. Cell

3. Cell Fusion – Fusion of two cell. Chromatin – Inside the nucleoplasm. Made up of - DNA + Protein + RNA . 2. Histones - 80 % total chlorophyll Protein. 3. Protoplast – 1. Dis- J.E. Purkinje and Mohi. 2. Def.- Cell without cell wall. 4. Mitochondria - name given by C. Benda and Discover by Hemming. Function – Respiration (ATP required at Aerobic Respiration). 5. Ribosome – Disc. By Hageman (RNA + Protein = Ribosome). Function – Synthesis of Protein. No lipid Content. 6. Endoplasmic reticulum (ER) – Porter (1948). 7. Golgi Complex – C. Golgi
