Il VACUOLO e la PARETE CELLULARE

🧬 LECTURE 33 of Giulia's Biology course Vacuoles are characteristic organelles of plant cells: large membranous sacs that contain various materials, such as water and waste products. The cell wall is the compartment outside the plasma membrane of plant cells. 🔎 LET'S DISCOVER THEM TOGETHER 📌 TIMESTAMPS ▶ 0:00 Introduction ▶ 0:31 Vacuoles ▶ 1:18 Maintenance of intracellular pH ▶ 2:38 One large vacuole or many small vacuoles? ▶ 3:30 Hydrostatic (or Turgor) Pressure ▶ 4:04 Plasmolysis ▶ 4:40 Plant Cells in Hypertonic Solution ▶ 5:15 Plant Cells in Hypotonic Solution ▶ 5:50 Cell Wall ▶ 7:02 Cellulose Fibrils ▶ 7:36 The Three Layers of the Cell Wall: Middle Lamella, Primary Wall, and Secondary Wall ▶ 9:28 Economic Value of the Cell Wall 🧲 RECOVER USEFUL LESSONS ▶ Carbohydrates - Polysaccharides:    • I CARBOIDRATI - i polisaccaridi   ▶ Introduction to the Cell:    • INTRODUZIONE alla CELLULA   ▶ Cells - Prokaryotic and Eukaryotic:    • LE CELLULE - procariotiche ed eucariotiche   ▶ The Golgi apparatus, lysosomes, and peroxisomes:    • L'APPARATO di GOLGI, i LISOSOMI e i PEROSS...   ▶ Mitochondria and chloroplasts:    • I MITOCONDRI e i CLOROPLASTI   ▶ The cytoskeleton:    • Il CITOSCHELETRO   📷 PHOTO SOURCE ▶ The video features parts of the "Animal Cell" and "Plant Cell" models from the "4D Science Model" series by the company "4D Master." ▶ Healthy basil: Photo by Ilaria from Pexels ▶ Wilted basil: Photo by Ron Lach from Pexels 📱 FOLLOW ME ON SOCIAL MEDIA ▶ Youtube: https://www.youtube.com/channel/UCsvK... ▶ Instagram:   / biologiacon.  . ▶ Facebook:   / biologia-con.  . ✉ CONTACT ME ▶ Email: [email protected]
