Plasmodesmata • Small Channels that directly connect the cytoplasm of neighboring plant cells • Establishing living bridges • Allows for direct transport between cells • Forms Synctium—multinucleate mass with cytoplasmic continuity
Cell Wall • Structural & Mechanical Support • Maintains cell shape • Resists internal turgor pressure of cell • Control rate & direction of growth • Regulate diffusion of material • Carbohydrate Storage • Protection against outside source
Nucleus • Highly specialized organelle served as the information hub and administrative center • Controls regulatory factors • Organizes the uncoiling of DNA to replicate key genes • Coordinates innumerable metabolic pathways • Growth, Division, Differentiation of the cell
Nucleolus • Contains densest region of Chromatin • Responsible for Synthesis of Ribosomes • Separated into 3 distinct Components • FibrillarCentres (FC) • Containing hundreds of rRNA genes • Dense Fibrillar Component (DFC) • Contains transcribing rRNA • Granular Component • Late processing site
Nuclear Envelope • Contains the contents of the nucleus • The space between layers connects with Rough Endoplasmic Reticulum • Allows for exchange of Macromolecules
