Definition: Biomass is defined as the mass of living material.

Example: Glucose produced during photosynthesis is used to create larger molecules like sucrose, cellulose, and starch.

Highlight: Leaves are specifically adapted for photosynthesis with chloroplasts containing chlorophyll and large surface areas.

Vocabulary: Translocation refers to the movement of food substances through phloem.

Definition: Transpiration is the evaporation and diffusion of water from a plant's surface.

Highlight: Xylem vessels are strengthened with lignin to prevent bursting under water pressure.

Example: The palisade layer contains numerous chloroplasts positioned near the leaf's surface for maximum light absorption.

Highlight: Waxy cuticle helps reduce water loss through evaporation.

Definition: Stomata are specialized pores in the lower epidermis that facilitate gas exchange.
