Leaf Structure
Plants faced dehydration when transitioning to land. Photosynthesis requires light and CO2. Leaf structure adapted to solve this. Angiosperm leaves have architectural adaptations to avoid desiccation. Upper and lower surfaces are covered with transparent epidermal cells coated with a waxy cuticle, reducing water loss. Between is the mesophyll, including palisade cells (columnar, below upper epidermis) for photosynthesis. Lacunar mesophyll (loosely arranged cells with spaces) also aids

Auditory System
The ear consists of three parts: the outer ear, middle ear, and inner ear.
Outer Ear
Composed of the pinna, ear canal, and eardrum, the outer ear collects and transmits sound waves to the middle ear. The ear canal contains small hairs and wax-producing glands for protection. The eardrum is a membrane separating the outer and middle ear.
Middle Ear
This section contains the tympanic cavity with three openings: one closed by the eardrum, and two inward openings called the oval window
