Here's why:
* Parenchyma cells are the most common type of plant cell and are found throughout the plant body.
* They are thin-walled and flexible, allowing them to store various substances.
* Storage parenchyma is a specialized type of parenchyma tissue specifically adapted for nutrient storage.
* These cells can store carbohydrates (like starch), proteins, fats, water, and even pigments.
Examples of storage parenchyma:
* Roots: Store carbohydrates and water for the plant.
* Stems: Store carbohydrates for future growth.
* Fruits: Store sugars and other nutrients for seed development and dispersal.
* Seeds: Store food reserves for the developing embryo.
While other tissues like xylem and phloem are essential for transport, they are not primarily involved in nutrient storage.
