How do plant cells differ from animal cells?

Plant cells and animal cells are both eukaryotic, meaning they possess a membrane-bound nucleus and organelles. However, they differ in several fundamental ways that support their distinct biological roles:1

• Cell Wall: Plant cells are surrounded by a rigid cell wall composed of cellulose. This structure provides mechanical protection and structural support, a feature absent in animal cells.21
• Chloroplasts: Plant cells contain chloroplasts, the organelles responsible for photosynthesis. These allow plants to convert light energy into chemical energy, a process animal cells cannot perform.21
• Vacuoles: While animal cells may have small vacuoles, plant cells typically contain one or more large vacuoles. These organelles store nutrients and maintain turgor pressure, which provides rigidity to plant tissues.21
• Intercellular Communication: Plant cells utilize plasmodesmata—microscopic channels that pass through cell walls—to allow direct communication between adjacent cells, a function analogous to gap junctions in animal cells.34
