Identifying Plant vs. Animal Cells

Key Differences

Animal Cells:

• Shape: Lacks a rigid and defined shape, displaying more flexibility.

• Chloroplasts: Absent; therefore, cannot carry out photosynthesis.

• Vacuole Size: Generally lack a large central vacuole, if present, it is smaller and numerous.

• Cell Wall: Do not possess a cell wall, instead have a flexible cell membrane.

• Lysosomes: Present, which contain enzymes for digestion and waste processing.

Plant Cells:

• Shape: Characteristically have a fixed, rigid shape due to the presence of a cell wall.

• Chloroplasts: Present, enabling them to perform photosynthesis and convert light energy into chemical energy.

• Vacuole Size: Contain a large central vacuole that stores water, nutrients, and waste, contributing to turgor pressure for structural support.

• Cell Wall: Composed of cellulose, providing structural integrity and protection.

• Lysosomes: Absent; instead, plant cells use the vacuole for waste degradation and storage.
