The diagram shows a typical plant cell. The outermost layer (1) of a plant cell is the rigid cell wall. Just inside the cell wall is the cell membrane (2). Plant cells usually have a large central vacuole (3) that occupies a significant portion of the cell volume, pushing the cytoplasm and other organelles towards the periphery. Within the cytoplasm is a network of membranes known as the endoplasmic reticulum (4). The nucleus (5) is a prominent, usually somewhat spherical, organelle containing the genetic material, often located near the periphery due to the large central vacuole.
Identifying key features of plant cells, such as the presence of a cell wall outside the cell membrane and a large central vacuole, is crucial for interpreting such diagrams. The relative position and appearance of organelles like the nucleus and endoplasmic reticulum within the cytoplasm should also be considered.
Option D correctly labels the parts as identified: 1 – cell wall, 2 – cell membrane, 3 – vacuole, 4 – endoplasmic reticulum, and 5 – nucleus. This arrangement is consistent with the structure of a plant cell, particularly the position of the large central vacuole. Options A, B, and C mislabel one or more of the indicated parts or their positions relative to each other.
