🔬 Mechanisms of Transport in Cells | Diffusion & Facilitated Diffusion | Class XI Biology (FBISE)

Описание: Understanding how substances move across the cell membrane is a core concept in Class 11 Biology (FBISE)—and this video makes it simple, clear, and exam-focused! 📘

In this lecture, you’ll explore mechanisms of transport in cells, with special emphasis on diffusion and facilitated diffusion. Using easy explanations, real-life examples, and clear diagrams, this video helps you grasp how molecules move without energy (passive transport) and why these processes are vital for cell survival.

🎯 What you’ll learn in this video:

What is diffusion and how it works in cells

Concept of concentration gradient

Facilitated diffusion and the role of carrier and channel proteins

Differences between diffusion and facilitated diffusion

Importance of passive transport in biological systems

FBISE exam-oriented points, definitions, and keywords

This video is perfect for XI Biology students, FBISE board preparation, quick revision, and building strong conceptual foundations for future topics like osmosis and active transport.
