Sclerenchyma Fibers

Thick-walled, rigid cells that provide structural support to plants, often found in stems, leaves, and roots.

Root Hairs

Small hair-like structures extending from a plant's root, increasing surface area for water and nutrient absorption.

Epidermis

The outermost layer of cells covering an organism, particularly in plants and animals, serving as a protective barrier against the environment.

Sclereid Cells

Specialized thick-walled plant cells that contribute to the hardness of nuts, seeds, and certain fruits.
