Photosynthesis and Plant Responses: Leaves and Photosynthesis

The video explores the structure and function of leaves in photosynthesis. It begins with an introduction to leaves as the primary photosynthetic structures in plants. The outer layer, known as the epidermis, is covered by a waxy cuticle to prevent water loss. The palisade layer beneath the epidermis is where most photosynthesis occurs. The spongy mesophyll, located below the palisade layer, facilitates gas exchange. Stomata, tiny openings on leaves, regulate water vapor and gas exchange, playing a crucial role in transpiration.

What are stomata and what role do they play in leaves?
