Parenchyma cells

Definition

Parenchyma cells are the most common and versatile cells in plants, involved in photosynthesis, storage, and tissue repair. They have thin cell walls and can divide to replace damaged cells.

5 Must Know Facts For Your Next Test

1. Parenchyma cells are found in the soft tissues of leaves, stems, roots, and fruits.
2. They play a crucial role in photosynthesis as they contain chloroplasts when located in green tissues.
3. These cells are capable of storing nutrients like starch, oils, and water.
4. Parenchyma cells have thin primary cell walls made of cellulose.
5. They can differentiate into other types of plant cells if needed for regeneration or healing.
