Final answer:
Epithelial cells and Vallisneria species differ in structure and function. Epithelial cells are taller and have a single layer with polarized organelles, while Vallisneria species have an elongated shape and multiple layers. Epithelial cells perform various body functions, while Vallisneria species have adaptations for photosynthesis and nutrient absorption.
Step-by-step explanation:
Epithelial cells and Vallisneria species differ in two main ways:
- Structure: Epithelial cells are taller than they are wide, while Vallisneria species have a more elongated shape. Epithelial cells have a single layer of cells, while Vallisneria species have multiple layers. Epithelial cells have a polarized distribution of organelles between their basal and apical surfaces, whereas Vallisneria species lack this polarity.
- Function: Epithelial cells are found in various parts of the body, performing functions such as absorption, secretion, and protection. Vallisneria species are aquatic plants, and their cells have adaptations for photosynthesis and nutrient absorption from the water.
