Identifying the False Statement: Plant vs. Animal Cells

This question requires identifying the incorrect statement comparing plant and animal cells. Let's analyze each option:

• Statement 1: Plant cells are generally larger than animal cells.

  This statement is generally TRUE. Plant cells often possess a rigid cell wall and a large central vacuole, which contributes to their typically larger size compared to animal cells.

• Statement 2: Animal cells do not have plastids.

  This statement is TRUE. Plastids, such as chloroplasts (involved in photosynthesis), are characteristic of plant cells and some protists, but are absent in animal cells.

• Statement 3: Plant cells have smaller vacuoles than those of animal cells.

  This statement is FALSE. Mature plant cells typically feature a large, central vacuole that can occupy up to 90% of the cell volume. In contrast, animal cells usually have smaller vacuoles that are more numerous and temporary, if present at all.

• Statement 4: Plant cells have cell walls, whereas animal cells do not.

  This statement is TRUE. The presence of a rigid cell wall outside the plasma membrane is a defining feature of plant cells, providing structural support and protection. Animal cells lack this cell wall.

Therefore, the false statement is that plant cells have smaller vacuoles than animal cells. The reality is the opposite.
