Cellular Showdown: Eukaryotes vs Prokaryotes PDF

Summary

This presentation provides a comparison of eukaryotic and prokaryotic cells, covering cell structures, functions, characteristics, and modifications. It also introduces cell types, such as epithelial, connective, muscle, and nerve cells, and discusses their functions and components.

CELLULAR SHOWDOWN: EUKARYOTES VS. PROKARYOTES—T HE ULTIMATE JARI ISOBEL D. MANGONON, CELLULARLPT AT THE END OF THE LESSONS, THE STUDENTS ARE A: Distinguish ABLE TO: M :Analyze some cell modifications that lead to prokaryotic and adaptation to carry out eukaryotic cells specialized functions (e.g., according to their microvilli, root hair). distinguishing features. T: Apply their understanding of the A: Classify different cell differences between prokaryotic and eukaryotic cells, various cell types, and types (of plant/animal cell modifications to real-world tissues) and specify the scenarios and advanced biological function(s) of each. studies.

Have you ever wondered how your heart cells never get tired, while your skin cells constantly renew themselves? ORGANIZATION OF LIFE 4 MAIN TYPES OF CELL EPITHELIAL CELL - coverings/ linings of organs and cavities - Closely-joined cells with tight junctions - Barrier for pathogens, mechanical injuries and fluid loss. EPITHELIAL CELL Cuboidal Epithelium - For secretion EPITHELIAL CELL Simple columnar epithelium - Brick shaped cells - For secretion and absorption EPITHELIAL CELL Simple squamous epithelium - plate-like cells - Exchange of materials. EPITHELIAL CELL Stratified Squamous Epithelium - Multi-layered - protection EPITHELIAL CELL Pseudo- stratified columnar epithelium - Single layer of cell - Lining of respiratory tract (lined with cilia) CONNECTIVE TISSUE - Bind structures together - Framework and support for organs and body - Store fat, transport, protection, repair. BLOOD - Made up of plasma - Water, salt &dissolved proteins - Erythrocytes (Oxygen) - Leukocytes (defense) - Platelets CONNECTIVE TISSUE PROPER (CTP) - Loose connective tissue (skin & connective fibrous tissue) - Collagenous fibers - Adipose Tissues (fats) CARTILAGE - Collagenous fibers (chondroitin sulfates) - Chondrocytes (collagen and chondroitin sulfates) - Cushion BONE - mineralized connective tissue made by osteoblasts (deposit collagen). - Combined with calcium, magnesium, and phosphate ions. MUSCLE TISSUES - Muscle fibers - Voluntarily / Involuntarily - Coming from nerve cells MUSCLE CELLS/ TISSUES SKELETAL MUSCLE - Striated & Voluntary - Move and perform activities - Respiratory mechanics; posture and balance - Protection CARDIAC MUSCLE - Contractility of the heart - Involuntary - Enough force and blood (metabolic demands) SMOOTH MUSCLE - Not striated - Stomach and Intestines - Urinary System NERVOUS TISSUES - Nerve cells (Neurons) - Glial Cells (Support) - Transmit electrical signals - Dendrite (receives impulses) - Axon (impulse transmitted to other neurons) CELL MODIFICATIONS FLAGELLA - Whip-like structure - Pushes the cell - Axoneme - Basal body - Dynein Arms (ATP) CILIA - Hair-like protrusions - Vibratory style - Axoneme and Basal Body - Dynein Arms MICROVILLI - Finger-like structures - Single-layer of epithelial cells - Supplied with blood - Assimilation, Adhesion, and aids in secretion - Increasing the surface area of the cell (minute folds) PSEUDOPODIA - Temporary extensions of the cytoplasm - “False feet” - Microfilaments NEXT MEETING: MODULE 3 LONG QUIZ
