Leaf structure
Narrated lesson · press play
The leaf is a food factory. Learn autotrophic vs heterotrophic feeding, the layers you see inside a leaf, and how each part is beautifully adapted to make food by photosynthesis.
What you'll learn in this lesson
By the end you should be able to (NSSCO Biology 3.6.1.1):
- Distinguish between autotrophic and heterotrophic nutrition
- Identify the cellular and tissue structure of a dicotyledonous leaf in cross-section
- Relate leaf structures to function: chloroplasts (photosynthesis), stomata and mesophyll (gas exchange), xylem and phloem (transport)
- Explain how the internal structure of a leaf is adapted for photosynthesis
