💡 Analysis & Explanation
Structural Boundary Distinction ▼
Plant cells are physically supported and protected by a rigid outer boundary called a cell wall, composed primarily of cellulose. This feature is completely absent in animal cells. Thus, statement 1 is correct.
Universal Cell Membrane ▼
The plasma membrane (cell membrane) is a universal structural component of all living cells. Therefore, plant cells definitely possess a plasma membrane, positioned just beneath their cell wall, making statement 2 entirely false.
Vacuole Configuration ▼
A defining characteristic of a mature plant cell is the presence of a single, massive central vacuole that maintains turgor pressure and stores nutrients. In contrast, animal cells, if they contain vacuoles at all, possess multiple smaller ones. Statement 3 is correct.
Conclusion ▼
Statements 1 and 3 correctly identify the biological differences.
