Cell Structure Concept Map FUNDAMENTAL UNITOF LIFE that serve as FUNCTIONS STRUCTURES variety of protein pi replication, RNA synthesi cellular respiration photosynthesis separates contents of nucleus from the cytosol synthesis of steroids, secretory proteins, detoxification of poisons modifies, stores and routes products of the ER moving products into, out of and within a cell contains digestive enzymes which break downsubstances storage of food, water, nutrients; osmoregulation. regulates traffic ofchemicals (plants, bact, fungi) between the cell and its surroundings l (plants) structural support (phnts (animals) support, communication, connection and junctions (animals) allows passage of material or current between cells (animals) prevents leakage of material animals) between cels 25mm, tubulin, organelle movement, separate chromosomes, cell motility cytoskeleton 7nm, actin, cell contraction, cytoplasmic streaming, cel cleavage keratin, 8-12 mm, organelle anchor, formation of nuclear lamina Solution Cell biology: 1. Rough endoplasmic reticulum. 2. Membrane bound organelles: Nucleus Mitochondria Chloroplast 3. End membrane system: Nuclear envelope Rough endoplasmic reticulum (making secretory proteins) Smooth endoplasmic reticulum (steroids production and detoxification reaction) Golgi apparatus Vesiclese(Transport endoplasmic reticulum to the Golgi apparatus). Lysosome Vacuoles Plasma membrane 4. Cell surface and junction: Cell wall Plasmodesmata (In plants it helps in communication between adjacent plants) Gap junction (animal communication) Tight junction (In animal it connects plasma membrane of adjacent cells) Gap junction (current passing through the gap junction do not leak into the intercellular space)
- 2. Tight junction (In animals prevent the contents of these organs from leaking into the surrounding tissues) 5. Cytoskeleton: Microtubules 25 nm Microfilament 7 nm Intermediate filaments 8-12 nm
